Evaluation of Water Deficit and Cycocel Spraying on Yield Element and Morphological Characterizes of two Cultivar Safflower

The present study was aimed investigating the effect water deficit and cycocel sparing on yield element of two cultivar of safflower, The experiment was carried out as a split split plot based on randomized complete block design with three replication. The result show that a most number of boll number related to without stress treatment(24.4) and a lost number related to cut of Irrigation in beginning of flowering stage(16.72). In without stress level a maximum of seed number rate of cut of Irrigation in beginning of flowering stage with means (37.068). padideh cultivar rate of Esfehan Local a most of seed number and cycocel spraying caused of increase in seed number(29.5372). also cycocel sparing caused of a most lateral branches (11.6561). the means compares shows that a maximum seed weight related to without stress level(32.399 Kg). Water stress caused of decrease yield in safflower herb, but cycocel spraying is growth regulator caused of decrease effects negative of water stress in our experiment plant and increase traits amount, also suggested that padideh cultivar in water deficit condition rate of Esfehan local cultivar toleranter, we can be with attention Damghan Climate condition, there Cultivate padideh cultivar.Also cycocel spraying caused decrease pressure of water deficit and increase yield, the resulted increase tolerance safflower in stress condition.
