| 摘 要： | 本文应用Hy—35型软X—射线仪对杉木、柳杉等15个树种种子进行摄影并进行定位发芽试验。根据各树种种子的X光片成像特征将种子划分为若干等级,将X光片上判读的百分率与定位发芽所得的发芽率进行统计分析,找出估测各树种种子发芽率的X光片判读等级。

| Abstract: | In this article, the photographs of 15 species (such as Cunning hamialanceolata and Cryptomeria fortunei) seeds were taken using Model Hy-35 softX-ray instrument and then a location germination experiment was conducted.According to X-polished section imagery features of the species seeds, the seedswere divided into some grades. Statistical analyses were made for the percent-ages read on the X-polished section and the germination percentages obtainedfrom the location germination to find out X-polished section reading grades of theestimation percentage of each species. The reading grades can be applied by rele-vant departments engaged in rapidly determining seed germination percentages. |
