| 摘 要： | 为了解大果榉结实、种子和幼苗特性,为大果榉繁育和推广利用提供理论依据及苗木生产基础,对大果榉的结实和种子特性进行了一些基础研究。结果显示:大果榉结实大小年明显,结实率低;沙藏层积处理大大提高了大果榉种子出芽率和整齐度;大果榉幼苗的分杈不仅极普遍,而且分杈高度低,分杈开始时间早。这些结果对大果榉的种子繁育和推广利用具有一定的理论和生产实际意义。

| Abstract: | The characteristics of fruiting,seeds and seedlings were studied for Zelkova sinica Schneid.The results indicated that fruiting rate of Z.sinica was low and featured with obvious on-year and off-year.Both seed germination rate and uniformity were significantly improved by using stratification treatment.Most seedlings of Z.sinica bifurcated at very early stage and at the very low stem position.These results have certain implication of theory and industry practice for Z.sinica seedling breeding,promoting and utilization. |
