چکیده

Fruit tree culture is at the brink of disaster in arid to semi-arid regions due low water availability. A pot experiment was carried out analyze whether foliar application salicylic acid (SA) can improve stress tolerance Syzygiumcumini. Saplings were subjected control (CK, 90% field capacity, FC), medium (MS, 60% FC) and high (HS, 30% along with 0.5 1.0 mM SA. Results showed that soil deficit significantly decreased leaf, stem total dry weight, leaf gas exchange attributes chlorophyll a, b. However, root weight root/shoot ratio increased under MS HS, respectively. Contrarily, SA improved b, attributes, production deficit. Concentration oxidants like hydrogen peroxide superoxide radicals, malondialdehyde electrolyte leakage deficit; however, plants sprayed increase concentration antioxidant enzymes dismutase, peroxidase, catalase ascorbate peroxidase. suggest help Syzygiumcumini saplings; validation results conditions necessary.

Physiological and biochemical responses involved in water deficit tolerance of nitrogen-fixing Vicia faba

Climate change is increasingly impacting the water deficit over the world. Because of drought and the high pressure of the rising human population, water is becoming a scarce and expensive commodity, especially in developing countries. The identification of crops presenting a higher acclimation to drought stress is thus an important objective in agriculture. The present investigation aimed to a...
