格氏栲等树种种发芽率的射线检验

A Study on the Inspection of Forest Tree Seed Germination Percentages by the Soft X-ray

本文用软Ｘ射线造影技术对格氏栲等１４个树种种子射线造影，制定Ｘ光片判别等级；与定位发芽进行对照，并进行统计分析，提出各树种种子射线造影测定发芽率技术．

In this article,the photographs of 14 species Castanopsis fargesii seeds were taken using soft X-ray instrument.According to X-polished section imdgery features of the species seeds,the seeds were divided into some grades. Statistical analyses were made of the percentages read on the X-polished section and the germination percentages obtained from the location germination to find out X-polished section reading grades of the estimation percentge of each species. The reading grades can be applied by relevant departments engaged inrapidly determining seed germination percentages.
