Abstract

A factorial experiment was conducted using a randomized complete design with three replications in the Greenhouse of Islamic Azad University of Fasa during summer 2000 for study of the effective factors on corn 704 inbred in seed vigor. The factors were water deficit, DEFOLIATION and NITROGEN APPLICATION. Water deficit and DEFOLIATION consisted of control, early water deficit and late water deficit, and control, early DEFOLIATION and late DEFOLIATION after flowering respectively, and nitrogen values consisted three levels of control, 9.2gN/m2and 18.4gN/m2. Results showed that by exception of seed viability, other seed vigor indices have significant effect. Control germ ination rate was 10.56% higher than germination rate average of early and late DEFOLIATION. Late DEFOLIATION electrical conductivity was 21.83 µS.cm-1.g-1 greater than early DEFOLIATION. NITROGEN APPLICATION increased germination percentage in all tests. Maximum germination percentage in all tests, germination rate and seed electrical conductivity obtained from interactive effect of control water deficit with application of 18.4gN/m2, and minimum germination percentage, germination rate and seed electrical conductivity obtained from interactive effect of early water deficit with not NITROGEN APPLICATION.
