对广东荔枝主要品种花粉的萌发率、贮藏性进行试验,‘糯米糍’最强,全花期萌发率最高年份达82.71％,依次是‘桂味’74.87％,‘怀枝’56.44％,‘三月红’54.74％,‘黑叶’44.78％,‘妃子笑’几乎没有生活力.一般盛花期比初、末花期强.7℃不萌发,15℃低,23℃或24～28℃最适.干燥器贮藏比自然贮藏大大延长花粉寿命,10天的萌发率‘桂味’58.93％,‘糯米糍’41.84％,‘怀枝’50.69％,均较‘黑叶’、‘三月红’耐藏;低温加干燥可延长贮藏.短时浸泡对萌发率影响不大,浸泡一天显著下降,浸泡两天几乎无萌发力.花蜜原液严重抑制萌发.
The germination rate and storage of the main varieties of litchi in Guangdong were tested. The highest percentage of germination rate was 82.71% in the whole flowering period, followed by 74.87% of the cinnamon, 56.44% of the wuzhi, Month red ’54 .74%, ’black leaves ’44 .78%,’ concubine laugh ’almost no viability .Percent flowering period than the beginning and the end of the flowering period .7 ℃ non-germination, 15 ℃ low, 23 ℃ or24 ~ 28 ℃ optimum Compared with the natural storage, the dryer prolongs the life of the pollen, and the germination rate of 10 days is 58.93% of the cinnamon, 41.84% of the glutinous rice and 50.69% of the wakame, compared with the black leaves, Storage at low temperature and drying prolong storage.The effect of short-term soaking had little effect on the germination rate, significantly decreased on one day of soaking and almost no germination on soaking for two days.
