  biological damage
     ~32P -B ray internal radiating natural dryed soybean seed showed that 32P -B ray can induce biological damage, for example, affecting height of seedling and the rate of growing to mature plant, and changing characters of booting. The higher the radiation intensity is, the worse the biological damage is.

Approaches to Quantitative Assessment of Biological Damage to Forest Communities under Technogenic Load
      
The method is proposed for assessing biological damage on the basis of the main characteristics of phytocenosis, such as its species diversity and the cenotic significance of its structural components.
      
The resultant integrated index of phytocenosis preservation (IIPp) characterizes the degree of biological damage, and its value depends on the load of toxicants and resistance of plant communities characteristic of different natural zones.
      
No large scale biological damage was observed from this localised spill.

Dry seeds of 3 varieties of wheat were treated with 2.58, 3.87, 5.16, 6.45 C/kg of gamma rays, 0.1%, 0.2%, 0.3%, 0.4% concentrations of EMS and their combination. The biological effects of M: and mutation frequency of M2 were studied.

本研究采用多种处理组合、处理方法以及多种生物学指标,探讨了γ射线与EMS复合处理小麦的诱变效应。 试验结果表明:γ射线与EMS复合处理的M_1代损伤随处理剂量的增加而增大,呈累加效应或协同效应。M_1代植株的生物学损伤与幼苗高度及幼苗根尖微核细胞密切相关。γ射线与EMS复合处理比单一处理提高了M_2代诱变效应。适宜的剂量组合可增加M_2代形态突变频率,扩大突变谱,并可增加某些数量性状的变异幅度。其中5.16C/kg的γ射线+0.3%EMS是比较理想的剂量。在复合处理中,可以M_1代幼苗根尖单微核细胞率估测M_2代的诱变效应。

Dry seeds of 3 varieties of wheat were treated with 2.58, 3.87, 5.16, 6.45 C/kg of gamma rays, 0.1%, 0.2%, 0.3%, 0.4% concentrations of EMS and their combination. The biological effects of M1 and mutation frequency of M2 were studied. The results showed that the biological injuries of M1 increased with dose of Y-ray and concentration of EMS.The additive effects were observed on percentage of the root tip cells with micronuclei, rates of emergence, seedling height; plant height and number of sterile spikes per plant and synergic effects on the sterile rate of the first spike and survival rate, M1 biological injuries were modified by different methods of pre-treatment. It was found that combination treatments with Y-ray and EMS were more effective than single treatment of either mutagen for inducing mutation in M2. The results of this study suggested that 5.16C/kg Y-ray + 0.3% EMS was the most effective for inducing mutation. The mutation frequency of M2 was closely related to the precentage of root tip cells with single micronuclei, which can be used for predicting the mutagenic effect of combined treatment.

~32P -B ray internal radiating natural dryed soybean seed showed that 32P -B ray can induce biological damage, for example, affecting height of seedling and the rate of growing to mature plant, and changing characters of booting. The higher the radiation intensity is, the worse the biological damage is. Meanwhile it can induce deficience of chlorophyll, mutation of booting character of ripening stage.
