| 摘 要： | 对在霜降日及提早半个月和1个月采收的黄山松种子的播种品质作了比较分析，结果表明霜降日采收的种子其千粒重、发芽率、发芽势和种子活力指数都要比提前采种的高11.4％～175．3％，采种时间越提前，品质越差。因此，分布在高海拔地区的黄山松采种时间应严格掌握在霜降前后，不能提前半月以上，否则将严重影响种子品质。

| Abstract: | Comparisons and analysis on sowing quality of Pinus taiwanensis seed collected on Frost's Descent (18th solar term), half month earlier and one month earlier demonstrated that thousand-grain weight, germination rate, germinationg potential and seed vigor index of seed collected on Frost's Descent was 11. 4%~175. 3% higher than that collected earlier. The earliest collection of seed, the worse of seed quality. Therefore, collection of seed in high elevation region should be around Frost's Descent, could not be earlier more than half month, otherwise seed quality would be seriousely influenced. |
