摘要:通过对10年生和30年生柚木种子园内不同种源及不同无性系之间开花结实和种子产量的差异性观测与分析表明,不同柚木种源及其不同无性系之间在花期和日开花时间上有重叠区,同时也存在较大的差异性,同一无性系的花期基本一致;不同无性系始花年龄不同,同一无性系的不同单株始花年龄也不完全相同;方差分析显示,不同无性系间平均每株种子产量呈显著差异(p<0.05),平均每株种子产量最高的无性系是最低的无性系的5.25倍。柚木的开花生物学特性限制了种子园的产量,选择花期尽量一致、单株种子产量高的不同无性系是营建高产优质柚木种子园的前提条件。本研究为今后营建柚木种子园在材料选择、种子园设计和管理调控上提供了科学依据。
Differences of blooming and seed production among different teak provenances and clones had been investigated in two teak clone seed orchards of 10 years old and 30 years old. The results showed that there were certain overlap of blooming period every year and blooming time every day among different teak provenances and clones, however, still much variation. Ramets form one clone had blooming synchrony. There were variations of first blooming ages among different clones and different ramets of the same clone. There was significant difference of seed productions among clones ( p 〈 0.05 ), the highest seed production per tree was 5.25 times than that of the lowest one. Teak flowering phenology might be scientific proof to low fruit production and seed orchard management.
