Abstract

The dormancy characteristic of potato tubers is analyzed from cultivars, self-pollination lines and hybrid lines. The result showed that dormancy phase and whole sprout phase of three types are , cultivars need 42d~70d and 35d~42d; self-pollination lines need 56d~77d和42d~49d ; hybrid lines need 56d~91d和49d~63d when they were stored in common condition.. The dormancy-time and sprouting-time of tuber can decrease 25.0~62.5% and the 34.7~71.4% by gibberellins treatment, but grow of buds would turn into week. The sprouting phase of tuber can be shorted 28.6~50.0% by the changed-temperature treatment, and the buds grow be become robust. The sprout of tuber can be inhibited by CIPC treatment effectively.

Key words
