Responses of Seed Germination and Seedling Growth of Picea asperata to Climate Warming and Enhanced UV B Radiation Influence of enhanced UV B radiation on H 2O 2 metabolism in wheat leaves Influence on microtubule in wheat mesophyll cell exposed to enhanced ultraviolet B radiation and He-Ne laser irradiation Effects of attenuated ultraviolet B radiation on soluble protein, photosynthetic pigments and flavonoids in tobacco leaves Effect of enhanced UV-B radiation on endogenous ABA and free proline contents in wheat leaves Interaction of UV-B Radiation and Anthracene on DNA Damage of Phaeodactylum tricornutum Effects of enhanced UV-B radiation on population quantity dynamics of weeds,soil macroanimals and wheat aphids in the wheat field ecosystem Present status and prospects in research on effect of enhanced UV-B radiation on plants THE EFFECT OF ENHANCED UV B RADIATION ON THE ACTIVITIES OF SOD,CAT AND POX IN WHEAT LEAVES Effects of enhanced UV-Bradiation on nutrients and accumulation of K of wheat field ecosystem Advance of plant response and adaptation under enhanced UV-B radiation and the effect of enhanced UV B on plant photosynthesis Effectsof enhanced UV-B radiation on energy accumulationand energy flow of wheat field ecosystem Effects of Supplemental UV-B Radiation on Fritillaria thunbergii Growth and Photosynthesis
