The Effect of Priming on Germination and Seedling Growth of Alfalfa (Medicago sativa L.) under Salinity Stress
Journal Title: Журнал ÑтреÑÑ-физиологии и биохимии - Year 2012, Vol 8, Issue 3
Abstract
Salinity stress is an abiotic stress which has harmful effects on germination, growth and yield of alfalfa ([i]Medicago sativa[/i] L.) in many parts of the world. Seed priming is a way of increasing salt tolerance of plants. In this study, the effect of seed priming on germination and growth of alfalfa seedlings, Bami cultivar, under salinity condition was investigated. According to germination percentage of seeds under In vitro conditions, salicylic acid, Vitamin B[sub]12[/sub] and distilled water were selected as primes under salinities of 0, 5 and 10 ds.m[sup]-2[/sup] NaCl solution for further studies. These studies were carried out in a factorial experiment based on Completely Randomized Design (CRD) with three replications in greenhouse under controlled condition (25°C in day/night). Parameters like percentage and rate of germination, dry and fresh weight of seedling and leaf number were measured. Based on our research All of the treatments (priming, salinity and the interaction of priming with salinity) significantly (p<0.01) affected Hypocotyl length and radicle length and in low level of salt (0 ds.m[sup]2[/sup]) germination and seedling growth indexes enhanced and also with applying salicylic acid both hypocotyl and radicle lengths improved.
