Effect of salinity stress on seed germination of two canola varieties
Journal Title: Scientia Agriculturae - Year 2013, Vol 2, Issue 2
Abstract
Seed germination of two varieties canola(Brassica napus L.). okapi and Regent×cobra was evaluated under four salinity levels(8-10-12) and with the control(0).we used NaCl in order to make salt solutions.germinated seeds were counted daily up to eight days. percentage and speed germination,length of shoot and root and fresh weight of shoot and root were measured. Increasing in salinity level lead to decreasing in percentage and speed germination.The highest and lowest germination were observed in Ec=0,Ec=12,with increasing salinity level,germination percentage,root and shoot length and fresh weight decreased,the Regent×cobra was superior cultivar in okapi.
