通过回归和方差分析发现,刚刚采集的银杏花粉生活力高达84.5％～98.12％。在一年生枝段上,小孢子叶球的下部比上部花粉生活力高13.36％。靛蓝(IG)更适于银杏花粉生活力的测定。在干燥器+冰箱贮藏条件下,银杏花粉30d后生活力下降到72.1％,60d后下降到62.4％,半年后下降到51.4％,一年后下降到1.5％。 Regression analysis and variance analysis showed that the viability of Ginkgo pollen collected just reached 84.5% -98.12%. In the annual branches, the lower part of microsporophyll leaves than the upper pollen viability by 13.36%. Indigo (IG) is more suitable for the determination of ginkgo pollen viability. Under the condition of dryer + refrigerator storage, the viability of ginkgo pollen decreased to 72.1% after 30 days, decreased to 62.4% after 60 days, decreased to 51.4% after half a year and decreased to 1.5% after one year.
