تأثیر تیمارهای آب گرم و هوای گرم بر جوانه‌زنی و عمر انباری غده‌های دو رقم سیب زمینی (Solanum tuberosum L.)

To evaluate the effects of heat treatments on sprouting weight, loss and other charactristics of two potato cultivars (Agria and Diamont) in cold (9±1) and ambient (18±1) storage, a series of experiments were conducted in 2004. In this study, after curing, the tubers of both cultivars were treated with warm air, at 25, 35, 45 and 57oC for 4, 8 and 12 h and with warm water at 22, 54 and 57 for 15 and 30 min. Treated tubers were packed in net bags and were kept in cold and ambinent storage for 2 and 4 months. The results of the study indicated that warm air at 45oC for 8 and 24 h and warm water at 57oC for 15 min. in comparison to control reduced the percentage of tuber sprouting significantly, without internal changes in tubers composition.
