Megjegyzések:	The valorization of by-products from green biorefineries is critical for environmental sustainability and economic viability. During the extraction of leaf proteins from alfalfa green biomass, significant volumes of brown juice (BJ) are generated. This study assessed the phytohormonal profile and antinutritional elements in BJ post-lacto-fermentation, examining its potential as a plant biostimulant. Fresh BJ was lacto-fermented using Pediococcus acidilactici, Lactobacillus paracasei, and Lactobacillus plantarum at 35 °C for 48 h. Phytochemical analysis via HPLC-MS/MS identified 18 saponins in BJ, with only medicagenic acid remaining post-fermentation, whose concentration increased 39-fold. Additionally, 23 plant hormone derivatives were quantified, with significant increases observed in indole-3-acetic acid, gibberellin GA1, jasmonic acid, and abscisic acid, while others like p-coumaric acid, caffeic acid, and ferulic acid decreased. These results demonstrate lacto-fermentation`s ability to stabilize BJ, reduce haemolytic saponins, and enhance phytohormone concentrations, supporting its utility as a sustainable plant growth enhancer.

Cím:	Elevated tolerance of both short-term and continuous drought stress during reproductive stages by exogenous application of hydrogen peroxide on soybean / Oqba Basal, Tahoora Batool Zargar, Szilvia Veres

Megjegyzések:	The global production of soybean, among other drought-susceptible crops, is reportedly afected by drought periods, putting more pressure on food production worldwide. Drought alters plants` morphology, physiology and biochemistry. As a response to drought, reactive oxygen species (ROS) concentrations are elevated, causing cellular damage. However, lower concentrations of ROS were reported to have an alleviating role through up-regulating various defensive mechanisms on diferent levels in drought-stressed plants. This experiment was set up in a controlled environment to monitor the efects of exogenous spray of diferent (0, 1, 5 and 10 mM) concentrations of H2O2 on two soybean genotypes, i.e., Speeda (drought-tolerant), and Coraline (drought-susceptible) under severe drought stress conditions (induced by polyethylene glycol) during fowering stage. Furthermore, each treatment was further divided into two groups, the frst group was kept under drought, whereas drought was terminated in the second group at the end of the fowering stage, and the plants were allowed to recover. After 3 days of application, drought stress signifcantly decreased chlorophyll-a and chlorophyll-b, total carotenoids, stomatal conductance, both optimal and actual photochemical efciency of PSII (Fv/Fm and Df/Fm, respectively), relative water content, specifc leaf area, shoot length and dry weight, and pod number and fresh weight, but signifcantly increased the leaf concentration of both proline and total soluble sugars, the root length, volume and dry weight of both genotypes. The foliar application of 1 mM and 5 mM H2O2 on Speeda and Coraline, respectively enhanced most of the decreased traits measurably, whereas the 10 mM concentration did not. The group of treatments where drought was maintained after fowering failed to produce pods, regardless of H2O2 application and concentration, and gradually deteriorated and died 16 and 19 days after drought application on Coraline and Speeda, respectively. Overall, Speeda showed better performance under drought conditions. Low concentrations of foliar H2O2 could help the experimented soybean genotypes better overcome the infuence of severe drought during even sensitive stages, such as fowering. Furthermore, our fndings suggest that chlorophyll fuorescence and the cellular content of proline and soluble sugars in the leaves can provide clear information on the infuence of both drought imposition and H2O2 application on soybean plants.

Cím:	Living mulch enhances soil enzyme activities, nitrogen pools and water retention in giant reed (Arundo donax L.) plantations / Nevien Elhawat, Andrea Balla Kovács, Gabriella Antal, Erika Kurucz, Éva Domokos-Szabolcsy, Miklós Gábor Fári, Tarek Alshaal

Megjegyzések:	Giant reed (Arundo donax L.) is one of the most well-studied perennial biomass crops because of its high productivity and potential to store carbon. Yet, little information on controlling weeds in giant reed plantations and their influences on the soil ecosystem is available. In the present study, three different weed control methods, i.e., intercropping (living mulch) with sweet clover (Melilotus officinalis L.), herbicide (glyphosate), and hoeing, were investigated in a 2-year giant reed farm. The intercropping presented significantly higher values (on average) of all the tested soil properties than herbicide and hoeing, except for the catalase activity and pH. The dehydrogenase, phosphatase, and urease activities in the soil under intercropping were higher than the herbicide by 75%, 65%, and 80% (on average), respectively. Also, the soil under intercropping had higher soil organic matter (SOM) and soil respiration than the herbicide by 20% and 25%, respectively. Intercropping also increased the content of N pools, i.e., NO3--N, NH4+-N, Org-N, and Total-N by 517%, 356%, 38%, and 137%, respectively, compared to herbicide. These findings illustrated that controlling weeds in biomass plantations through legume intercropping brings benefits not only to soil properties but also to biomass productivity.
