Silicon vs. selenium: A comparative study in mitigating osmotic and drought stress in durum wheat (Triticum durum Desf.).

Silicon (Si) and selenium (Se) are recognized as beneficial elements that may significantly improve plant's tolerance to drought stress. However, their action and efficiency on germination, biometric and physiological attributes are rarely compared on durum wheat under water-deficit conditions. This study highlights the effect of Si (15 mg L) and Se (1 and 2 mg L) seed priming on germination kinetic of four durum wheat varieties ('Karim', 'Maali', 'INRAT100', and 'Dhahbi') under osmotic stress (150 g L PEG6000).

Induction of lytic Enzymes by Extracts from Resistant and Susceptible Cultivars of Pea ( L.).

Being pathogenic fungi, produce various extracellular cell wall-degrading enzymes (CWDEs) that degrade the polysaccharides in the plant cell wall. They also produce mycotoxins that contaminate grains, thereby posing a serious threat to animals and human beings. Exposure to mycotoxins occurs through ingestion of contaminated grains, inhalation and through skin absorption, thereby causing mycotoxicoses.
