Abstract:
Objective
In order to investigate effects of different concentrations of poly amines Sprimidin and Putrescine on germination of Arg cultivar under salinity stress. Methods
This experiment was conducted as factorial based on completely randomized design with four replicates in agronomy and plant breeding laboratory, Agricultural department, Islamic Azad University, Varamin-Pishva Branch in spring of 2014. First factor was four levels of salinity including S1: 3.87, S2: 5.95, S3: 10.25 and S4: 12.87 ds/m and the second factor was three levels of poly amines including H0: control (not application of poly amines), H1: Putrescine 2.5 m/mol and H2: Sprimidin 5 mmol/L. coleoptile and cleorhiza length, cleorhiza number, coleoptile, cleorhiza and seedling dry weight, Tissue water content (TWC), germination percent and number of damaged seeds were measured. Results
Analysis of variance showed that coleoptile and cleorhiza length, cleorhiza dry weight affected by salinity and hormone levels at 1% of probability level. There was no significant difference among other treatments for other properties. Results of this experiment indicated that following increasing salinity, sever reduction in germination-dependent properties were observed.Keywords:
