【Objective】 The purpose of the experiment is to reveal the relationship between cyclobutyl pyrimidine dimers (CPDs) accumulation and UV-B sensitivity in mung bean cultivars.

Effects of enhanced UV-B radiation on Alopecurus japonicus:the weed of wheat field;

Effect on nitric oxide messenger under UV-B radiation in Chlorella pyrenoidosa;

The effects of UV-B radiation on the mortality and ingestion and filtering rate of adult females and males of Schmacheria inopinus by exposure to varying dose of UV-B irradiance were examined in the laboratory.

Effects of enhanced Ultraviolet radiation-B on plant form of spring wheat in arid and semiarid regions of middle-high elevation;

To estimate the effects of enhanced ultraviolet radiation-B on growth of maize and design answerer plans, the article studied influence of enhanced ultraviolet radiation-B on maize in middle-high elevation and arid regions.

Interaction of UV-B radiation enhancement and athracene on the growth of three species of red tide microalgae;

The effect of UV-B radiation enhancement on the growth competition between Alexandriun tamarense and Heterosigma akashiwo;

Effects of supplemental UV-B radiation on growth,physiology and alkaloid of Fritillaria Thunnbergii Miq.;

Influences of enhanced ultraviolet radiation(UV B,280～315nm)on population quantity dynamics of weeds,soil macroanimals and wheat aphids in the wheat field ecosystem were investigated,Under UV B radiation,species number and population quantity of weeds and soil macroanimals decreased,species diversity changed,total biomass of weeds reduced.

Enhanced UV B radiation led to changes of the composition of fatty acids as well as decrease of IUFA in chloroplast membrane, increase in MDA content and accumulation of ABA and proline.
