Abstract

In order to investigate the effect of drought stress and delay sowing date on SEED QUALITY of advanced RAPESEED cultivars (Brassica napus L.), a field experiment was conducted as factorial split-plot arranged in a randomized complete block design in three replications in 2004/06 in Karaj Seed Improvement Institute in this study consideerd ‎two factors: Irrigation at two levels:80% of evaporation as control (I1), drought stress started from stem elongation stage(I2), and planting date: normal planting date as fall (D1) and delay planting date as winter(D2), as main plots, cultivars were: RGS003(V1), Sarigol (V2), Hyola401 (V3), Hyola420 (V4), Hyola330 (V5), RGS006 (V6), RG4403 (V7), RG405/03 (V8), RGAS0324 (V9), RG405/02 (V10), as sub factors. The results showed that there were significant difference on Vigor, cold test, E.C and ph test (1% level). maximum vigor and tolerance to cold test, E.C and pH belonged to normal irrigation, fall sowing and D1I1 interaction. Also in D1I2 and D2I1 had significant different at three primary characters. Study of Simple cultivars effect show that RGS003, Sarigol, RGS006 and Hyola420 c.v. were the best at vigor, cold, E.C and pH tests respectively. Also at the interaction effects of treatments Hyola401 and Sarigol c.v. in the normal irrigation and fall planting date, have a maximum germination at the vigor and cold test respectively. But result shows that, at the delay and drought stress conditions E.C test results showd that minimum pass through from the seed coat belonged to D1I1V5. Then these seeds at this condition had minimum decline that can recommend them for long time store.
