寒地苹果和海棠花粉生活力的试验

Research on Pollen Vigour of Apple Trees in Frigid Region and Chinese Flowering Crab-Apple

新苹1号、新帅和海棠的花粉生活力之间有极显著的差异,而黄太平和海棠的花粉生活力之间无显著的差异;品种对寒地苹果的花粉生活力有显著的影响;不同枝型对寒地苹果的花粉生活力有显著的影响,然而对海棠没有显著的影响。

Result of this experiment indicate:the difference exists at highly significant level between the pollen vigour of different varieties and that of Chinese flowering crab-apple while there is no significant difference between the pollen vigour of Huang Tai Ping and that of Chinese flowering crab-apple; Varieties influence the pollen vigour significantly; Types of branch have significant influence on pollen vigour and no influence on Chinese flowering crab-apple.
