Linum usitatissimum L. is one of the economically important oilseed crops and salt stress is one of the major environmental challenges affecting several physiological processes in plants. The present investigation was carried out to study the effects of NaCl on some physiological and biochemical responses in two cultivars of L. usitatissimum. Twenty-one-day-old-plants were exposed to salt stres...

Using phosphate fertilizers and wastewater as a source of irrigation residuals from industries have considerably increased the level cadmium (Cd) in soil which severely reduced growth yield crop. L-glutamic acid (L-Glu), an amino acid, plays key roles plant stress tolerance. Hence, current study was conducted to determine potential role L-Glu pre-treatment alleviating Cd-induced toxicity lentil...

AP is involved in the destruction of harmful H202. In soybean (Glycine m a x [LI Merr.) root nodules, AP initiates a sequence of coupled redox reactions (ascorbate-GSH pathway) that results in peroxide scavenging (Dalton et al., 1986). The ascorbate-GSH pathway occurs in other plant tissues and has been extensively studied in chloroplasts where photoreducing conditions lead to the production of...

To evaluate the physiological responses of chrysanthemum to silicon spray in non-stress conditions, this study was performed in two separate experiments (at 4 to 5 and 8 to 12-leaf stages) as a factorial randomized completely design with two factors: silicon source (in two levels: sodium silicate and calcium silicate) and the concentration of silicate at five levels (0, 50, 100, 150 and 200 mg ...

Leaf spot disease caused by Alternaria pathogens seriously threatens peony production. The physiological mechanism of resistance to the pathogen is little reported. This study aimed reveal defensive peonies in response tenuissima. disease-resistant (R) variety ‘Zi Fengyu’ and susceptible (S) ‘Heihai Botao’ were employed, some parameters leaves analyzed after inoculation with A. tenuissima, main...

In order to evaluate the effects of seed priming with salicylic acid (SA) (0, 2, 10, and 20 mM) to increase salt tolerance (0, 50, 100, 150, and 200 mM NaCl) in medicinal plant Dracocephalum moldavica at seed germination, an experiment was conducted as factorial in a completely randomized design with four replicates. The assessed parameters included germination percentage and rate, len...
