ABSTRACT
To evaluate the effects of priming on germination and morpho-physiological traits of the Coriandrum sativum, an experiment consisting of laboratory, green house and field tests was conducted in 2016. The purpose of this research was to improve and modify the uniformity in germination, growth rate and subsequently high performance and production of C. sativum. Coriander seeds, in comparison with control group, were pre-treated with water, folic acid, humic acid, ascorbic acid, P, K2SO4, zinc, GA3 and IAA. Analysis of variance in laboratory, green house and field tests of all traits had significant statistical difference in probability level of 1%. Extraction from primed seeds revealed that priming decreased harmful fatty-acids. Evaluation of stepwise regression analysis indicated the accession of seven traits entered into the predictive equation model with coefficient of determination value of 0.973. These were seven traits which explained 97.3% of changes associated with trait of total dry weight of root. According to the results of correlation analysis the secondary vigour, dry weight of root, fresh weight of root and root’s diameter were in model with total dry weight and it was significant in probability level of 1%.
Key words : Coriandrum sativum L, fatty acid, germination, morpho-physiological traits, pre-treatment
