تأثیر سالیسیلیک اسید بر صفات جوانه‌زنی بذر گیاه عدس (توده محلی صفاشهر) تحت تنش شوری

Seed priming is a technique by which seeds before placing the substrates in terms of physiological and biochemical get ready for germination. Salicylic acid (SA) role in the regulation of various processes of plant growth, ion uptake and germination is playing. To evaluate the effect of lentil seeds pretreatment by SA in terms of salinity stress a factorial experiment was conducted in a completely randomized design with three replications. Treatments included SA in level of 1 and 3 mM, hydropriming as control and salinity levels (0, 50, 150 and 200 mM NaCl). The results showed that the interaction of salinity and SA on percentage, rate and uniformity of germination was very significant. The root and shoot length and dry weight and seed vigor is affected by salinity significantly and demonstrated a significant decrease with increasing salt concentration. The highest percentage and rate of germination was obtained at 1 mM SA and 50 mM salt. The lowest percentage of germination was obtained in 1 mM SA and 200 mM salt. The results showed that seed priming by 1 mM SA in semi-saline areas can increase germination rate and percentage of the lentils.
