Megjegyzések:Series of laboratory and green house experiments were conducted at the Environment, Natural Recourses and Desertification Research Institute (ENDRRI), NCR, Khartoum, Sudan. Thirteen salts (sodium acetate trihydrate, sodium phosphate dihydrate, magnesium sulfate heptahydrate, sodium sulfate, potassium chloride, calcium chloride, potassium bicarbonate, sodium phosphate monohydrate, magnesium chloride, sodium pyrophosphate trihydrate, trisodium acetate, ammonium acetate and potassium phosphate dihydrate) and citric acid were evaluated on Striga hermonthica germination and haustorium initiation in response to the germination stimulants (GR24) under laboratory condition. In green house experiment, growth of sorghum cultivars (WadAhmed, AbuSabeen and Tabbat) infested with Striga seeds primed in sodium acetate trihydrate and potassium phosphate dehydrate (selected based on laboratory experiments results) were examined. Laboratory experiments results showed that germination of Striga significantly decreased with increasing salts concentrations.Sodium acetate trihydrate displayed highly suppressive (52-100%) effects on Striga germination. Striga seeds previously conditioned in 13 salts irrespective to their concentrations reduced haustoria. Greenhouse results displayed that sodium acetate trihydrate and potassium phosphate dehydrate sustained the lowest and highest Striga emergence, respectively as compared to the corresponding controls. Sorghum varaiety Wad Ahmed displayed the lowest Striga emergence, irrespective to salts type and concentrations. Treatment of sorghum Wad Ahmed with sodium acetate trihydrate reduced Striga height and dry weight. Potassium phosphate dihydrate enhanced Striga height and dry weight. Sodium acetate trihydrate gave the highest sorghum growth, irrespective to cultivars. Sorghum Wad Ahmed and Abu Sabeen cultivars treated with potassium phosphate dihydrate or sodium acetate trihydrate, respectively, sustained the highest growth. Sodium acetate trihydrate and potassium phosphate dihydrate increased sorghum dry weight as compared to corresponding control.

Cím:Fungal elicitor effected growth of Striga in-vitro co-cultured with sorghum / Magda, M. M. Ahmed, Hussien M. Daffalla, Magdoleen G. Osman, Magdoline Mustafa Ahmed, Mohammed Mahgoub Hassan, Migdam E. Abdel Gani
Dátum:2016
Megjegyzések:In the present investigation fungal elicitors (0.0, 1.0, 5.0, 10, 20 and 50 mL/L) were evaluated for ability to induce germination of Striga hermonthica and sorghum growth. Fungal elicitors induced Striga germination in a concentration dependent manner. In presence of sorghum, the germination inducing activity of fungal elicitors was lowest at the lower elicitor concentrations. The activity, invariably, increased on increasing concentrations level (10-50 mL/L). At 50 mL/L elicitor, germination was increased to 63% and 75% irrespective to time interval. In absence of sorghum, fungal elicitors at 10 mL/L sustained the highest Striga germination then declined with increasing elicitor concentrations. In absence of the sorghum, fungal elicitors at 5-10 mL/L induced Striga germination. However, 50 mL/L of the fungal elicitor induced maximum germination in presence of the sorghum. In terms of Striga length, the maximum height was recorded at 5 and 50 mL/L elicitor in presence and absence of the sorghum, respectively. Sorghum height, in presence or absence of Striga, was considerably affected by fungal elicitor compared to the control. Among the fungal elicitor concentrations, irrespective to presence of Striga, 5 mL/L proved to be more ability to stimulate the growth of sorghum. Furthermore, fungal elicitor at 1.0 mL/L sustained the maximum root and root/shoot ratio in presence or absence of Striga. The improvement of root growth over the control was occurred only at the least fungal extract concentration and significantly decreased with increasing doses. The differential germination displayed by S. hermonthica in response to fungal elicitor merit further research and has to be taken into account in designing management strategies.

Megjegyzések:Laboratory experiments were conducted to assess the effects of some fungal isolates (supernatant and pellet) on germination of Striga seeds. Five fungal isolates were isolated from soil samples of Striga-infested or non infested sorghum fields in Sudan. Isolates differed in their effect on Striga seeds germination. Treatment with isolate Ai 41 resulted in seeds germination rates of 0.00 to 4.19% for pellet and culture filtrates, respectively. In comparison, seed germination rates were 44% and 51.96% for water and culture medium controls, respectively. The study further included investigation of the effect of isolate Ai 41 on germination of Striga seeds in the presence of two growth regulators, the auxin Indole-3-Butyric Acid (IBA) and the cytokinine Benzyle Amino Purine (BAP). High concentrations of IBA and BAP, reduced germination of Striga seeds conditioned in water significantly, in response to GR24 as compared to media control. The suppressive effects of isolate Ai 41 consistently increased with increasing both BAP and IBA concentration. In among all treatments, results indicated that IBA alone or in combination with fungal isolate Ai 41 completely inhibited Striga seed germination in response to GR24. This study indicates that some microorganisms could be employed as antagonistic to Striga. Their use as potential bioherbicides to control Striga appears promising

Cím:Effects of some fungal isolates on germination and haustorium initiation of striga hermonthica (del.) benth / Magdoline M. Ahmed, Mohammed M. Hassan, Ahmed M. E. Rughium, Awad G. Osman, Migdam E. Abdelgani, Abdelgabar E. Babiker
Dátum:2013
Megjegyzések:Two laboratory experiments were conducted to assess the effects of fungal isolates on germination and haustorium initiation of Striga hermonthica. Forty three fungal isolates were isolated from infested and un-infested sorghum fields with Striga hermonthica. A preliminary screening was conducted to assess the effect of these isolates on germination of preconditioned Striga seeds. Sixteen fungal isolates in addition to a standard strain Trichoderma viride were selected according to their effects on Striga seeds germination and haustorium initiation. In the first experiment isolates and strain were assessed for their effect on germination of Striga seeds during conditioning in response to GR24. The second experiment was conducted to study the effects of fungal isolates and T. viride on Striga haustorium initiation. The results revealed that six fungal isolates had no effects; six isolates reduced germination (34- 93%) significantly while other isolates significantly enhanced germination (15?59%) of Striga seeds. Moreover, isolate Ai 41 reduced germination over 90% as compared to the corresponding control. Similarly, few fungal isolates inhibited haustorium initiation while some had no effect. Isolate Ai 50 was the only isolate that completely (100%) inhibited haustorium in response to DMBQ. The study concluded that some fungi can be used as control agents against Striga and suggested that further studies had to be conducted in the green house and field to verify theses results and develop a strategy for the use of fungi as mycoherbicides against Striga.

Megjegyzések:A series of laboratory and green house experiments were conducted to investigate the efficacy of Trichoderma harzianum fungi, bacteria (Flavobacterium, Bacillus megatherium var. phosphaticum (BMP) and Azomonas) on Striga hermonthica early developmental stages, incidence and sorghum growth under laboratory and greenhouse conditions. The first laboratory experiment results showed that application of BMP + Flavobacterium significantly inhibited S. hermonthica seeds germination during and after conditioning in response to GR24 concentrations as compared to medium control. In the second laboratory experiment, application of the filtrate of T. harzianum alone or in combinations with bacteria significantly inhibited S. hermonthica germination and haustorium initiation as compared to the corresponding control. From greenhouse experiment results, S. hermonthica emergence significantly reduced by T. harzianum and insignificantly by the combination of Flavobacterium + BMP + T. harzianum. T. harzianum followed by the combination of Flavobacterium + BMP gave the highest increment in plant height. T. harzianum significantly increased sorghum number of leaves as compared to the infested control. The combination of Flavobacterium + BMP + T. harzianum gave the highest number of leaves. The combination Flavobacterium + BMP gave the highest sorghum shoot dry weight, followed by T. harzianum. While the highest sorghum root dry weight was obtained from the combination of Flavobacterium + BMP + T. harzianum. Generally, the combination of T. harzianum + Flavobacterium + BMP reduced S. hermonthica infestation and enhanced sorghum growth in comparison to the infested control.

Megjegyzések:BACKGROUND: Orobanche crenata is a holoparasitic weed that seriously attacks legumes and depend entirely on their hosts for all nutritional requirements. A wide variety of approaches physical, cultural, chemical and biological have been explored against root parasite. Current means for controlling parasitic weeds are focusing on reducing soil seed bank and inhibiting early developmental stages. OBJECTIVE: Laboratory and greenhouse experiments were conducted to investigate the effects of bacterial strains and isolates cultures and filtrates, on early developmental stages of Orobanche crenata and to explore their potential in O. crenata control. RESULTS: Results of in vitro experiments revealed that germination of O. crenata significantly decreased after inoculation with bacterial cultures or filtrates. Bacterial isolates (ISO43 and ISO44) and strains of Bacillus circulans, B. megatherium var. phosphaticum (BMP) and the combination of BMP plus Rhizobium leguminosarum bv. viceae (TAL1399) significantly reduced germination as compared to other microbes and controls. With respect to the effects of bacterial cultures or filtrates on haustorium initiation, results displayed that B. circulans, BMP, BMP+R. leguminosarum bv. viceae (USDA 2478) and ISO44 significantly suppressed O. crenata haustoria factor as compared to the corresponding control. In the in vivo experiment, irrespective of faba bean cultivars and bacterial inoculation, O. crenata emergence progressively increased with seed bank size. Faba been inoculated with bacterial combinations of BMP+TAL1399 and BMP+USDA2478 significantly reduced O. crenata emergence and dry weight. In general, Basabeer cultivar invariably displayed better growth than Selaim. Faba bean height and dry weight invariably decreased with increasing seed bank size. The increase in faba bean growth parameters is consistent with the observed delay and decrease in O. crenata emergence in response to treatments. CONCLUSION: Improving soil fertility by using beneficial microorganisms appeared to decrease O. crenata infestation and its suppressiveness effects on host growth. Use of potential bacterial strains and isolates could be incorporated into existing Orobanche crenata management practices.

Megjegyzések:Striga hermonthica (Del.) Benth is an obligate, root-parasitic flowering plant that limits cereal production in sub-Saharan Africa. In this study, two greenhouse experiments were carried out to screen the optimum intercropping ratio (2:1, 2:3 and 2:6) of sorghum and groundnut and to evaluate the effect of intercropping, bacterial strains (Bradyrhizobium spp. and Bacillus megatherium var. phosphaticum BMP) and inorganic fertilizers (nitrogen and phosphorus) on S. hermonthica incidence and sorghum growth. The sorghum Wad Ahmed cultivar and groundnut Sodari cultivar were used for both experiments. All experiments were laid out in a randomized complete block design (RCBD) with four replicates. In the first experiment, results showed that intercropped sorghum with groundnut at the ratios of 2:1 and 2:3 performed the best in terms of both reducing S. hermonthica emergence (by 44% and 41%) and increasing sorghum growth (by 24% and 52%), respectively compared to the sole sorghum crop. S. hermonthica numbers were decreased as the proportion of groundnut increased in the intercrop. In the second experiment, results revealed that S. hermonthica emergence in sole sorghum crop showed significantly higher number than the intercropping. Overall means showed that S. hermonthica emergence was reduced by 48% in groundnut intercrop, 78% in intercrop treated with nitrogen and92% when inoculated with Bradyrhizobium + BMP + nitrogen. Furthermore, sorghum/groundnut intercropping inoculated with the bacterial combination, invariably achieved the highest reductions in S. hermonthica emergence and the highest increase in the measured sorghum growth parameters

Megjegyzések:A series of laboratory and greenhouse experiments were conducted at the Environment, Natural Resources and Desertification Research Institute (ENDRI), National Centre for Research (NCR) and College of Agricultural Studies, Sudan University of Science and Technology (SUST), Sudan, to examine the efficacy of the fungus Trichoderma harzianum, culture age, inoculum type, application time, fungal extract, compost and bacterial strain on Striga hermonthica germination and sorghum infestation. The highest significant (P?0.05) inhibition on S. hermonthica germination was obtained at 10 days by T. harzianum culture as compared to both controls. Application of all T. harzianum aqueous and ethyl acetate extracts concentrations significantly (P?0.05) reduced S. hermonthica seed germination as compared to the corresponding control. T. harzianum inoculum extracted by ethyl acetate reduced germination by 97%. T. harzianum aqueous 100% induced germination during conditioning by 64 % in response to GR24 (0.1ppm). All types of T. harzianum inoculum (Autoclaved, culture and filtrate) significantly (P?0.05) reduced germination, with application of T. harzianum culture filtrate gave the highest reduction on germination as compared to control and other inoculums. Application of the 3 inoculums at 2 hours reduced germination percentage more than at 4 hours. Filtrate and culture inoculums at 2 hours reduced germination by 79 and 68%, respectively. The combination of compost 100%+ T. harzianum + BMP+Flavobacterium reduced germination by 68%. The greenhouse results showed that the combination of compost plus BMP+ Flavobacterium gave lowest number of S. hermonthica emergence and the highest sorghum plant height. The combinations of compost with T. harzianum and with BMP+ Flavobacterium significantly reduced S. hermonthica dry weight, increased sorghum shoot and root dry weight insignificantly as compared to the control.

Megjegyzések:Two sets of greenhouse experiments were conducted to investigate the effects of i) sorghum intercropping with cowpea genotypes and seeds level of Striga on Striga incidence on sorghum Wad Ahmed, ii) intercropping of cowpea, bacterial strains and inorganic phosphorus on Striga hermonthica parasitism and sorghum growth. Treatments were arranged in a randomized complete block design with four replications. In the first greenhouse experiment, irrespective of intercropping, Striga emergence progressively increased with seed bank size. Intercropping, significantly, reduced Striga emergence and dry weight. Base on the overall means of Striga emergence, intercropping of B301 and T100K-901-6 cowpea genotypes with sorghum reduced Striga emergence by 95- 45% and 96-52% at 1 ? 16mg/pot of Striga seed bank, respectively as compared to control. A consistent progressive decline in sorghum height, leaf area and dry weight was evident in sole sorghum crop with increasing Striga seed bank size. , Intercropped sorghum, invariably, improved sorghum growth than sole sorghum. In the second experiment, intercropping with cowpea, inoculated with Rhizobium leguminosarum alone or in combination with phosphorus, delayed and repressed Striga emergence, significantly in comparison to sole sorghumwith a reduction ranging between 98 and 92%, respectively. However, significant increments of leaf area were only attained when sorghum intercropped with Rhizobium inoculated cowpea, alone or in combination with phosphorus at 92 kg ha-1 by 56 and 50%, respectively. Intercropping with cowpea inoculated with Rhizobium alone or in combination with phosphorus at46 kg ha-1 increased sorghum dry weight significantly as compared with the corresponding control. In conclusion, cowpea genotypes inoculated with the bacterial combination, invariably achieved the highest reductions in Striga emergence as well as the highest increase in the measured sorghum growth attributes

Megjegyzések:A field experiment was conducted at two experimental sites at Khartoum, Sudan, season 2016- 2017, to study the effects of Trichoderma harzianum, Bacillus megatherium var. phosphaticum (BMP), Rhizobium leguminosarum biovar viceae strain (TAL1399), Nitrogen and Phosphorus fertilizer (two levels each) on Orobanche crenata incidence and faba bean growth and yield. Nitrogen was applied as urea 95.2kg/hectare (N1) or 190.4kg/hectare (N2) and phosphorus as triple super phosphate 95.2kg/hectare (P1) or 190.4kg/hectare (P2), Treatments were laid out in a Randomized Complete Block Design (RCBD) with four replicates. Results showed that O. crenata displayed maximum emergence (76.50 plants/m2 ) in the untreated control at 100 days after sowing, the combination of T. harzianum + BMP+TAL1399 + fertilizers both levels significantly (P?0.05) reduced O. crenata emergence as compared to the control at both sites. Application of T. harzianum alone or in combination with BMP+TAL1399 + N2P2 significantly (P?0.05) reduced O. crenata dry weight as compared to the control, irrespective to the site. T. harzianum alone or in combination with N1P1 or BMP+TAL1399+N2P2 and the combination with BMP+TAL1399+N2P2 significantly (P?0.05) increased plant height as compared to the infested control.

Megjegyzések:Striga hermonthicais a serious parasitic weed on cereal crops which causes severe damage to its host. Three endophytic bacterial isolates (isolated from sugarcane crop) and two carbohydrates, glucose and sucrose, were evaluated in a laboratory, for effects on the parasite germination and haustorium initiation. The results indicated that bacterial isolates ISO20, ISO29 and ISO30,significantly inhibited germination as compared to the controls, irrespective of conditioning status of Striga seed. The two carbohydrates, alone or in combination with bacterial isolates, were evaluated on Striga germination. Results revealed that each of the two carbohydrates, irrespective of the concentration, reduced germination significantly by 29 - 100 %,as compared to the control. The depressive effects of the carbohydrates on Striga germination increased with increasing concentrations, in response to GR24. Furthermore, glucose was more suppressive to Striga germination than sucrose. The combination of glucose and sucrose sustained the highest inhibitory effects (63 - 67 %) as compared to each carbohydrate alone and the controls. However, the combination between bacterial isolates plus glucose or sucrose was the most inhibitory than each bacteria or carbohydrate alone. They reduced germination by 79 and 100 % in response to GR24 as compared to conditioning media. Moreover, both carbohydrates reduced haustorium initiation, significantly in response to DMBQ. Furthermore, seeds conditioned in sucrose or glucose at the highest concentration (10 g/100 ml) and similarly treated with DMBQ did not form haustoria. Bacterial isolates were identified using morphological and biochemical tests. The establishment of the inhibitory effect of the most promising bacterial isolateISO20(Gluconacetoacter spp.)on early developmental stages of Striga is a step towards utilizing such bacteria as biocontrol agents against S. hermonthica. In conclusion: carbohydrates enhanced the efficacy of the bacteria as a suppressor of the parasite and reducer of the parasite debilitating effects
