油松种子活力的比较研究

A Comparative Study on Sced Vigor of Pinus Tabulaeformis Carr.

在沙盘模拟和场圃试验二种条件下,研究了不同年份油松种子活力。结果表明,不同年份的油松种子的出苗率与脱氢酶的活性呈正相关,与电导率呈负相关。

The vigor of seeds harvested in various years of pinus tabulaefor-mis carr.studied under two circumstances of sand plate model and nurserygerminating test showed that the seedling emergence percentage of seeds indifferent years was positively correlated with the activity of dehydrogenaseand negatively correlated with the electric conductivity.
