مقایسه تاثیر سن فیزیولوژیک غده بذری سیب زمینی و استعمال هورمون برون زاد جیبرلیک اسید بر خصوصیات کمی، غالبیت انتهایی و زودرسی محصول سیب زمینی

in this research we have evaluated the effect of storage conditions and application of CA3 honnone on apical dominance, pricocity and reproducing of stolons in potato seed. Therefore, three cultivars of potato have been treatmented with two methods of storing and three levels ofCA3 containing 0,5,10 PPm. These treatments have been Aplied in factorial experiment based on randomized comptit block design. characters that we have determined namely: 1. Number of constructed-main stems 2.number and mean weight of large 'tubers 3. Number and mean weight of potato seed (average tubers) 4.number and mean weight of microtubers (minitubers). Datas of this research detected that all parameters have significantly different at 1% alfa level with Duncasn's Multiple Rang Test. Five part per milions of CA3 in secondary storage condition with all three cultivars had most effectiveness on potato seed production. Hormon treatments had highest effect on producing of potato seed in tubers that have younger point on physidogicaI age. "Draga" had uppennost level of main stems in comparison with two other cultivars. The effect of storage condition in 5 and 10 ppm of CA3 on producing amount of main stem hadn't any different significant at 1 % alfa level. In totaIly, "Marfona" had highest yield in most treatment and average weight of tubers was 3.41 kglm2.
