摘要：试验结果表明：柿不同物种品种的花粉粒大小、发芽率有极显著差异，不完全甜柿、油柿、君迁子花粉发芽率在４０％以上，完全甜柿、涩柿品种的花粉发芽率低。５～２０ｍｇ／ｋｇ硼砂能明显提高花粉发芽率。花粉在常温下仅能贮藏５～１０ｄ，而常温干燥、低温干燥可分别贮藏１５～２０ｄ、３０ｄ以上。甜柿和部分涩柿品种单性结实力弱，生产上需配置授粉树。“禅寺丸”是花期中等品种的授粉树。“正月”是多数花期中、晚品种的授粉树。柿属种间杂交亲和性差。柿品种间杂交坐果率有较大差异，以“正月”为父本的授粉组合坐果率较高。
There were great differences among different persimmon varieties and species for pollen size and pollen germination.The pollen germination rates for pollination variant of non astringent, Diospyros oleifera and D.lotus were greater than 40%,but lower for pollination constant of non astringent. Boron (5～20 mg/kg) greatly improved pollen germination rate.The storage period of fresh pollen in normal temperature range was from 5～10 days,but 15～20 days in normal temperature and dry condition,and over 30 days in cooler temperature and dry condition.Parthenocarpy capacity was poor for non astringent varieties and some astringent varieties,so pollen supplying trees are necessary to be planted in fruit gardens.Zenjiomaru variety was used as pollen trees which have middle flowering period.But Shougatsu variety has middle or later flowering period.The compatibility among species from persimmen genus was poor,but there were greater differences for fruit setting among varieties,with higher setting rate if Shougatsu was used as male parent tree. 5 superior male parent varieties were suggested.
