| 摘 要： | 以引进的美国核桃品种‘维纳’、‘艾米格’和新疆本地品种‘温185’和‘新新2号’为试材,研究分析不同品种的植物学和生物学特性、花芽分化过程以及相关成花基因的表达。结果显示:4个品种在树体生长、枝芽发育特性、物侯期以及成花率和坐果率方面没有明显差异。在结果枝同一坐果部位形成双果、三果或以上的能力‘新新2号’明显强于‘维纳’,但‘新新2号’的果实大小和单果重都低于‘维纳’,而‘维纳’平均结果母枝上形成侧花芽的数量和坐果率高于‘新新2号’。从萌芽到开花结束直至当年侧芽发育过程中‘维纳’混合芽中的JrFT和JrLFY基因表达也高于‘新新2号’,而同时期的JrFLC基因表达则相对较低,说明‘维纳’在花芽分化和花器官形成过程中通过高表达JrFT和JrLFY基因,低表达JrFLC基因促进结果母枝上形成大量侧花芽,并利用大量侧花芽抽生结果枝坐果,形成较大的果实,使得最终产量并不低于同一个坐果部位大量着生2个或多个果实的‘新新2号’品种。
