Abstract
The effects of artificially simulated UVB radiation reduction under field conditions at Qianyanzhou region of Jiangxi Province on the growth and the contents of chlorophyll and endogenesis hormones,indoleacetic acid(IAA),abscisic acid(ABA),gibberellinA_3(GA_3)and zeatin(Z),of rice variety 'Xieyou 432'were studied.The results indicate that the UV-B radiation reduction induces the contents of chlorophyll change significantly,but no difference among the ambient control and treatments of UV-A and UV-A+UV-B is observed.The contents of IAA,GA_3 and Z with the UV-A+UV-B treatment are significantly lower than those of ambient control,decreasing by 40.42%,48.60%,36.21%,respectively.Compared with the UVA treatment the contents of IAA,GA_3 and Z in the UVA+UV-B treatment are decreased by 36.52%,70.94% and 54.54%,respectively.The ABA content of UV-A+UV-B treatment decreases by 29.74% compared with that of the ambient control,and by 5.19% compared with the UV-A treatment.The results also indicate that reduced UV-B radiation has changed the contents of the four endogenesis hormones of the investigated rice cultivar,and accordingly may have adverse effects on the process of growth and development of rice.
