A pot experiment was conducted in lath house at the College of Agriculture, Kerbala on March, 10^th /2016 and on September 16^th,2016 for spring and fall seasons respectively to study the effect of genotype (local Mullah Ahmed and hybrid), ethephon (0, 50, 100 and 150  mg.l^-1 ), boron (0 and 30 mg.l^-1) and their interaction on sex expression and yield of the summer squash plant. A factorial experiment within a completely randomized design was adopted. Plants were sprayed with ethephon at 4-5 leaf-stage and boron was sprayed at 6-8 leaf-stage for spring and fall seasons. The results showed that the hybrid genotype significantly surpassed in most floral growth characters and yield (female flowers, sex ratio, fruit num... view more»
