摘要:
2014年对浙江省天台县天台鹅耳枥(Carpinus tientaiensis)的花期物候、花形态特征进行观测,并测定其花粉生活力和雌蕊柱头可授性。结果表明,天台鹅耳枥雄花始花期早于雌花,雄花散粉与雌花柱头可授期重叠时间为15 d,较大的空气湿度和阴雨天气可能会对授粉产生不利影响;天台鹅耳枥初花期花粉萌发率最高,达到10.83%,是人工采集花粉的最佳时期;0.6%琼脂粉+0.005%和0.01%的硼酸+1%的蔗糖最有利于花粉的萌发;雌蕊柱头可授性在开花1 d后达到最佳状态,可授期为5 d。
Abstract:
Observations were made on flowering season and flower morphology, and determination was carried out on pollen viability, stigma receptivity of Carpinus tientaiensis in 2014 in Tiantai, Zhejiang province. The results showed that staminate flowers had earlier flowering stage than pistillate ones, and they had only 15 days overlaps. High air humidity and rainy days may have negative influence on pollination. Pollen germination rate at initial flowering stage was the highest, topped to 10.83%, resulting the best time for pollen collection. Culture with 0.6% of agar+0.005% or 0.01% of boric acid+1% of sucrose had the best result for pollen germination. Stigma got to the optimal receptivity one day after flowering, and lasted for 5 days.
