摘要： 对核桃楸开花特性进行了观察, 结果表明:核桃楸多数植株为雌雄异熟, 有的植株上雌花先开(雌先型), 有的植株上雄花先开(雄先型)。每一植株上雌雄异熟的次序是相当稳定的。并且多数能为雌先型植株提供授粉机会的雄先型群体, 其雌花期与雌先型群体的雄花期也能较好的吻合。但是少数花期不同的同一类型(即:雌先型与雌先型或雄先型与雄先型)植株之间也有授粉机会。在坐果率、产量、核果的整齐度、放叶早晚、落叶期、形态差异的调查分析中未发现异熟性与这些性状上有必然的联系。

Abstract: By observation of the flowering feature of Juglans mandshurica, the dichogamy of it was revealed. The results showed that:(a)The dichogamy of Juglans mandshurica was steady.(b)If the staminate flowering of protandrous meet with the pistillate flowering of protogynous, the pistillate flowering of protandrous could also meet with the staminate flowering of protogynous. But some staminate flowering of protandrous meet with the pistillate flowering of protandrous and staminate flowering of protogynous meet with the pistillate flowering of protogynous in different plant. (c)The dichogamy was not significantly related to the yield, the degree of uniformity of nut, the percentage of fertile fruit, morphology.
Key words: Juglans mandshurica, dichogamy, protogynous, protandrous
