Abstract:

Nine Prunus avium L.varieties including ‘Van’, ‘Hongdeng’, ‘Juhong’, ‘Pynhonnouhax’, ‘Kocmhqecka’, ‘Hpectnkhan’, ‘Jiahong’, ‘8-129’, ‘8-102’ were used as materials, the changes of cold indexes, electrical conductivity, MDA content, soluble solid and pollen vitality were observed and determined at bud and florescence stage under low temperature stress. The results showed that the descending order of cold resistance of different varieties were ‘Van’＞ ‘Hongdeng’ ＞ ‘Juhong’＞‘Pynhonnouhax’＞ ‘Kocmhqecka’＞ ‘Hpectnkhan’＞ ‘Jiahong’＞ ‘8-129’＞ ‘8-102’.At the same temperature, the descending order of cold resistance of floral organ were ‘petal’＞ ‘pedicel’＞ ‘stamen’＞ ‘pistil’. The bud stage appeared strong cold resistance.The pollen vitality quickly decreases with increased low temperature stress.
