为研究锥栗花粉直感效应,选用‘华栗1号'、‘华栗2号'、‘华栗3号'和‘黄榛'4个品种为试材,进行自交、异交授粉试验,以自然授粉作为对照,共20个授粉组合,分析不同授粉组合的果实成熟期、结实率及果实品质等,结果表明:锥栗在果实成熟期、坐果率、结实率、果实大小、可溶性糖、脂肪、蛋白质、直链淀粉和维生素C等方面表现明显的花粉直感效应,而在出籽率、总淀粉含量和含水量等方面无明显花粉直感效应;通过平均隶属函数法分析20个授粉组合,‘华栗2号'ב华栗3号'得分最高,‘黄榛'自交得分最低。因此,‘华栗2号'ב华栗3号'为首选授粉组合。

The pollen xenia phenomenon not only affects the setting rate but also influences the appearance and quality of nuts. To elucidate this phenomenon, we investigated the pollen xenia effect in Castanea henryi, using the cultivars Huali 1, Huali 2, Huali 3 and Huangzhen as materials. Twenty combinations of self-, cross-, and natural pollination were undertaken in a Chenzhou chestnut orchard of Hunan Province. The results revealed that there were significant difference among the pollination combinations in terms of fruit ripening, fruit setting, si...
