软 X 射线是一种波长为0.62～0.71(?)(埃)的射线,国外在鉴定林木、作物种子形态及质量方面应用较多,国内也在开始研究应用。中科院植生所用软 X 射线追踪,研究水稻开花期遭遇冷害的机理,取得了较好的效果。本实验是应用软 X 射线追踪,研究水稻开花时间及灌浆速度。它较之过去称重法有很多优点,可以进行活体观察,能够较精确地观察单穗及单粒的发育动态,而且不破坏样本,适于小群体如杂种后代、少量名贵材料遗传特性和生态特性观察研究之用。当然,
Soft X-ray is a wavelength of 0.62 ~ 0.71 (?) (A) of the rays abroad in the identification of trees, crop seed morphology and quality of more applications, the country is also beginning to study and application. The soft-X-ray tracing used by the Chinese Academy of Sciences for plant production has been used to study the mechanism of chilling damage during flowering and achieved good results. This experiment is the application of soft X-ray tracing, research rice flowering time and filling speed. Compared with the past weighing method has many advantages, can be observed in vivo, can more accurately observe the development of single ear and grain development, and does not destroy the sample, suitable for small groups such as hybrid offspring, a small amount of valuable materials, genetic characteristics and ecology Characteristics of observation and research purposes. of course,
