e0“Alfalfa (Medicago sativa L. cv. Siwa 1) seeds were germinated in polyethylene glycol (PEG 4000) of different concentrations and with or without putrescine”
e4“In a pot experiment, drought stress was imposed by decreasing the soil moisture”
e5“Growth criteria, contents of proteins, chlorophyll a, b and carotenoids, as well as Hill reaction activity decreased while the hydrolytic enzyme activity and total soluble and reducing sugar contents increased under drought stress”
