Abstract

RESPONSE SURFACE ANALYSIS was applied to data of seed germination rate and shoot length of three alfalfa cultivars (Hamadany, Gharay Yonjehe, Nik shahri) in relation to TEMPERATURE and salt integrated conditions. Completely randomized factorial experiment with four replications on five levels of TEMPERATURE (5, 10, 15, 20, 25oC) and 4 levels of sodium chloride salinity (control, 0.05, 0.1, 0.2 molar) was conducted. Response surface was developed for each cultivar using multiple-regression techniques (in such situation this procedure is best appropriate for quantitative factors). Results showed that partial regression coefficient for germination rate and shoot length equations in each cultivar were varied and so response surface were changed. Coefficients of the best equation from the response surface of each cultivar for each salt level through a series of TEMPERATUREs were changed. In general, result showed that by increasing of salinity and TEMPERATURE range, germination rate and shoot length were decreased. These comparisons form a statistically valid basis to select the most adapted cultivars and predict the best planting time at suitable TEMPERATURE and salt stress condition.
