Abstract

Bu derlemede patates (Solarium tuberosum L) yumru verimi ve oluşumunu etkileyen faktörler araştmlmıştır. Bitkide doğal olarak bulunan hormonlar (gibberellik asit, sitokinin vb) bitkinin toprak altı ve toprak üstü organları, çevresel etmenler (sıcaklık, ışık) incelenmiştir. Ayrıca yumru oluşum sinyali ve taşınması konusuna da yer verilmiştir. Yumru oluşumu gibberellik asit-sitokinin yada gibberellik-absisik asit oranına bağlı olduğu öne sürülmüş en uygun çevresel etmen kısa gün ve düşük sıcaklık olarak saptanmıştır.

The Factors Effecting the Tuber Formation in Potatoes (Solanum tuberosum L.)

Abstract

In this rewiev, the factors which affect tuber yield and tuber formation were studied in potato (Solarium tuberosum L). The natural hormones (gibberrelic acid and cytokinin) found in plants, root and shoot tissues, environmental factors (temperature and light) were determined. Besides these factors, tuber formation signal and transportation were also studied Tuberization depends on gibberrelic acid- cytokinin or gibbcrrelic-abscisic acid ratio and it was determined that optimum tuberization occurs in short days and low temperatures.
