近几年来,林业研究部门在解决杨树种子贮藏的技术问题上,已经有了相当的成效。但一般苗圃对这方面的工作却做得很少。其原因不外乎贮藏条件差和技术问题没有得到很好的解决。我们曾经失败过,在1958年里,初步获得了成效,现介绍如下,供研究参考。杨树种子的特点是:种粒小,种皮薄,无胚乳,内部贮藏养分不多,如不采取措施,长期存放易受环境(温度和湿度)的影响,迅速失去发芽力。根据这些特点,贮藏杨树种子必须创造良好的环境,严格的控制温度和湿度以及种子的含水量等,尽可能抑制种子的呼吸作用。我们采取的方法是:首先选择颜色新鲜(淡黄色)而又饱满的种子(我们采用的是呼市落地扫起来的种子),使其含水量阴干到气干程度,这时种子的
In recent years, the forestry research department has achieved considerable success in solving the technical problems of poplar seed storage. But nurseries generally do very little in this area. The reason is nothing more than poor storage conditions and technical problems have not been well resolved. We have failed in 1958, initially achieved results, are presented below for reference. Poplar seeds are characterized by: small seeds, thin seed coat, no endosperm, internal storage of nutrients is not much, if not take measures, long-term storage vulnerable to the environment (temperature and humidity), the rapid loss of germination. According to these characteristics, poplar seeds must be stored to create a good environment, strict control of temperature and humidity and seed water content, as much as possible to inhibit the respiration of the seeds. Our approach is: First, choose the color of fresh (light yellow) and full of seeds (we use the call to sweep the ground floor of the seeds), the moisture content of dry to air-dried degree, then the seeds
