摘要:

为寻找湖北省香榧生产中适合的花粉,开展香榧花粉直感现象研究,探讨湖北榧树花粉的利用价值。试验以香榧结果母树为母本(A),选用浙江嵊州木榧(B)和湖北通山榧树(C)作为父本进行人工授粉,检测比较2种父本来源组合的果实形态指标、经济指标和养分含量。结果表明,嵊州花粉和通山花粉对榧籽大小和榧核形状表现出花粉直感现象;对榧籽单籽重、单核重和出仁率等经济指标,对榧籽含油量、蛋白质、维生素E和脂肪酸等主要营养成分没有明显的花粉直感现象。说明通山花粉可以在香榧生产中应用,通山榧树雄株资源有开发利用价值。

Abstract:

In order to find suitable pollen in Torreya grandis production in Hubei Province, the research on pollen xenia effect was carried out, and the utilization value of T. grandis pollen was discussed. Pollen from Shengzhou (B) and pollen from Tongshan (C) were selected as male parents, and they were pollinated on seed trees (female parent A) by hand, and then the fruit morphology index, economic index and nutrient content of the combination of two paternal sources were compared. The results indicate that pollen from Shengzhou and Tongshan has pollen xenia effect on seed size and nutlet shape. For economic indicators such as single seed weight, single nutlet weight and kernel yield rate, and for the major nutrients such as oil content, protein, vitamin E and fatty acid in seeds, there is no obvious xenia effect. The study indicates that the T. grandis pollen from Tongshan can be used in production, and the resources of the male T. grandis in Tongshan are valuable for development and utilization.

Key words: Torreya grandis, pollen xenia, dioecism, pollination, Torreya seeds
