在辐射育种的研究工作中,要想得到准确的生物量,首先要有准确的物理量。γ射线和活体植株间的作用是紧密的能量传递过程,它将部分能量传递给活体植株各个器官,而某些器官在一定生长期吸收能置的多少又与遗传效应直接相关。但是,由于各器官不同生育期各元素的百分含量不同,在同一照射量下,吸收能量的多少也不同。辐射育种工作者在考虑与遗传密切相关的器官剂量给予置时,转换因子就显得特别重要。所以测定活体植株不同时期各器官的元素百分含量,并计算出相应的X-D转换系数,对于由照射量(R)转换为吸收剂量(Gy)是必要的。
In radiation breeding research, in order to get accurate biomass, we must first have an accurate physical quantity. The role of γ-rays and living plants is a compact energy transfer process, which transfers some of the energy to various organs of living plants. However, the absorption capacity of some organs in a certain growth period is directly related to the genetic effect. However, due to the different organs of different growth stages of the different percentage of elements in the same exposure, the amount of energy absorbed is also different. Radiation breeders are especially important when considering the dose of organs that are closely related to heredity. Therefore, it is necessary to measure the percentage of elements in different organs of living plants and calculate the corresponding X-D conversion coefficient, which is necessary for the conversion from irradiation dose (R) to absorbed dose (Gy).
