| 摘 要： | 插穗长度是影响落叶松嫩枝扦插生根的重要因子之一。笔者于清原县大孤家林场和宽甸县太平哨林场采用不同长度插穗进行了嫩枝扦插试验。结果表明:10~16 cm长度插穗是落叶松嫩枝扦插的最适宜长度,26~30 cm长度插穗生根最差。相关分析结果表明,插穗长度与生根率呈极显著负相关,插穗长度与生根匀称率呈显著负相关。

| Abstract: | The cuttings length was one of the most important factors that affects rooting characters of latch tender branch. In this paper, the cutting experiment was conducted in Dagujia of Qingyuan county and Tai ping shao of Kuandian county by different cutting length.The results showed that the optimum cuttings length of larch tender branch to rooting was 10 -16 cm; and the the worst cuttings length to rooting was 26 - 30 cm. Correlation analysis revealed that the cuttings length had a extremely notable negative correlation with the rooting rate and well-balanced rate of rooting. |
