Investigation of different pre-treatments effects on seed germination and seedling traits of various chickpea (Cicer arietinum L.) cultivars.

Effects of seed priming (soaking in water، osmopriming whit polyethylene glycol and potassium chloride، soaking in gibberalin and hydropriming) on germination rate (GR)، mean germination time (MGT)، time reach to 50% germination (T50)، root and stem length، seedling dry and fresh weight in three chickpea cultivars (Qazvin، ILC482 and ILC3279)، was investigated. Cultivars differed significantly for total trait. The results indicated soaking in water and GA3 had highest effect on the germination rate، and between them not observed significant difference. In this study، hydropriming، water and GA3 treatments had similarly reducing effect on MGT and T50. Osmopriming with PEG and KCL had the most and the less effect on root and stem length، seedling dry and fresh weight in ILC3279 than other cultivars، respectively. ILC3279 had the less seedling dry and fresh weight، but it had the most values mentioned in PEG treatment، that indicates the positive priming effects on low physiological quality cultivars.
