Influence of salicylic acid pre-treatment on emergence and early seedling growth of cucumber (Cucumis sativus)under salt stress
Salicylic acid (SA) is a common, plant-produced signal molecule that is responsible for inducing tolerance to a number of biotic and abiotic stresses. An experiment was therefore conducted to test whether the application of SA at various concentrations (0, 0.25, 0.50 or 1.0 mM) through a seed-soaking method would protect cucumber (Cucumis sativus L.) seedlings subjected to salt stress. Aft...
متن کاملEffect of Water Stress on Seed Germination of Agropyron Elongatum, Agropyron Desertourm & Secale Montanum
Physiological effect of six levels of water stress (0, -0.1, -.03, -0.6, -0.9 and -1.2 MP) was studied on seed germination and plumule as well as radicule growth length in three species namely: Agropyron elongatum, Agropyron desertourm and Secale montanum. Polyethylene glycol (PEG) was used to provide appropriate water potentials. A total of 100 seeds in four replications (Petri dishes) were so...
متن کاملThe effect of salicylic acid and gibberellin on enzyme activity and germination characteristics of wheat seeds under salinity stress conditions
ABSTRACT: Seed priming was used in wheat seeds to increase germination characteristics and tolerance on stress exposure. Wheat seeds were treated with salicylic acid and gibberellin. After 8 days our results showed that, seed priming treatments significantly (p≤ 0.01) affected germination percentage, normality seedling percentage, germination index and seedling length. Seed priming with salicyl...
متن کاملEffects of priming with salicylic acid on germination traits of Dracocephalum moldavica L. under salinity stress
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...
متن کاملComparative Effects of Hydropriming and Halopriming on Germination Performance of Secale montanum Guss. under Salinity Stress
Salinity stress is one of the most important abiotic stress factors limiting the plants' growth. Seed priming is known as a method which improves the germination performance in seeds in stress conditions. The objective of this study was to compare the effectiveness of Hydropriming and Halopriming on germination performance of Secale montanum while growing under the NaCl-salinity stress. Hydropr...
