20个小麦品种对UV-B辐射增强响应的形态学差异

Abstract

Abstract: Differences in morphological response of 20 wheat cultivars to enhanced ultraviolet radiation(UV-B,280～315 nm) were investigated under field conditions. Results showed that differences were observed in LAI,plant height, internode length and stem diameter between the cultivars. The responses of the cultivars in plant height and internode length were consistent and in significant positive relationship. Based on morphological response index(MRI),tolerant cultivars (MRI>-8 5) include Liaochun 9>Wenmai 3>Dali 905>Lanzhou 80101>Mianyang 26>YV 97-31>Bi 90-5,and sensitive cultivars(MRI<-49 4) include Huining 18>Fan 19>Chuxiong 8807>My 94-9>Qian 14> Yunmai 39>Longchun 16. Smaller angles of spread of leaves of the tolerant cultivars and wider angles of the sensitive cultivars were observed.Effect of UV-B radiation inhibiting incidence of stripe rust disease on wheat was also discovered.

Key words: intraspecific difference, morphology, wheat, morphological response index, radiation, UV-B
