沈阳市主要树木种子成熟期和千粒重与辽宁东部山区近似,随着气候的变化,有一些树种略早于桓仁、宽甸。沈阳市主要树木种子成熟期、出种率、千粒重和一公斤种子粒数的测定工作,过去有人搞过一些,但远不能适应目前科研和生产的需要。我们从1978年至1983年底,做了一点工作,现将六年的记录整理如下。 Shenyang City, the main tree seed maturity and 1000-grain weight and mountainous areas in eastern Liaoning approximation, with the climate change, some trees slightly earlier than Huanren, Kuandian. Shenyang City, the main tree seed maturity, the seed rate, 1000-grain weight and one kilogram of seed particle size determination, some people engaged in the past, but far can not meet the current needs of scientific research and production. We did a bit of work from 1978 to the end of 1983, and we now have six years of records as follows.
