Cím:	Effects of fungal liquid culture aqueous extract and phytohormones Striga hermonthica (Del.) Benth.germination / Magdoline Mustafa Ahmed, Mohammed Mahgoub Hassan, Migdam Elsheikh Abdelgani
Dátum:	2014
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:	Impact of Trichoderma harzianum and bacterial strains against Striga hermonthica in Sorghum / Mona A. Azarig, Mohammed M. Hassan, Ahmed M. E. Rugheim, Magdoline M. Ahmed, Rania A. Abakeer, Rashida M. A. Abusin, Migdam E. Abdelgani

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.
