李品种花粉活力及授粉初步研究
0
()
摘要:
采用过氧化物酶染色法,测定李11个品种类型的花粉活力,并对其自花结实能力进行研究。结果表明,李品种花粉活力普遍较低,一般不超过40%;李品种存在明显的部分自交不亲和现象,自花授粉结实率最高不足20%。同时,根据不同组合杂交授粉试验结果和开花物侯期观察分析,为生产上综合经济性状表现突出的栽培品种安农美李、早黄李和蜜思李筛选出适宜的授粉品种。对李树自花结实率低的原因和李树授粉品种选配中应考虑的问题进行

Study on Pollen Vitality and Pollination of Plum Cultivar
()
Abstract:
The pollen vitality of 11 plum cultivars was tested by means of peroxidase staining and the self fruitful ability of them was studied.The results showed that the pollen vitality was lower and less than 40 percent generally,and the self fruitiful rate was less than 20 percent because of part self imcompatibility.According to the results of artificial cross pollination and the observation of full bloom,some suitable pollinizers were selected for the cultivars:Annong meili,Yellow early and Methely.The reason for the lower rate of fruit set by self pollination and the problems which should be considered in the selection of pollinizer were also discussed.
Key words:  plum,pollen,pollination,pollinizer,
