| 摘 要： | 为研究云贵鹅耳枥在喀斯特地区植被恢复中的作用,采用样木调查法,对黔中喀斯特山区云贵鹅耳枥种群种子结实量及其种子质量进行调查分析。结果表明,鹅耳枥种群种子结实量与林木径级呈正相关;第一极枝和二级枝上的种子结实量与全株的结实量相关性显著;种子千粒重与林木径级关系不明显;低径级林木种子净度及发芽率较高。

| Abstract: | The seed-setting quantity and seed quality of Carpinus pubescens population were surveyed by the sampling method to study its role in re-vegetation in Karst area.The results showed that there was a positive correlation between its seed-setting quantity and tree diameter size,a significant correlation in seed-setting quantity between the first and second branches and the whole plant,no obvious correlation between its 1 000-seed weight and tree diameter size,and the purity and germination rate of seeds from s... |
