ABSTRACT
Field studies were conducted for two consecutive years to determine the potential for alterations in flavonoid contents and the intraspecific variation in (absorption 305 nm) sensitivity of 28 wild sugarcane (S. spontaneum L.) clones to enhanced ultraviolet-B (UV-B, 280-315 nm) radiation. The supplemental UV-B radiation was 5.00 kJ m-2, simulating a depletion of 20% stratospheric ozone at Kunming (25°N, 1950 m). Across all clones tested in the present study, the effect of UV-B radiation on flavonoid contents in different developmental stages of 28 wild sugarcane clones were observed both in 2003 and 2004. In general, intraspecific responses of flavonoid contents of wild sugarcane clones to enhanced UV-B radiation existed both in 2003 and 2004. Response sensitivities of flavonoid contents of 28 wild sugarcane clones to UV-B radiation in different stages have the following sequence: elongation > flowering > tillering both in 2003 and 2004. So, intraspecific difference to UV-B radiation was indicated by the percentage change of flavonoid contents in elongation of wild sugarcane in 2003 and 2004. According to the ranking of intraspecific sensitivity and hierarchical cluster analysis in elongation, tolerant clones were 83-181, II91-5, 90-22, 93-25, I91-38, II91-13 and 92-11, sensitive clones were 92-26, 92-36, 83-153 and II91-93. 83-181 was the most tolerant clones both in 2003 and 2004. Wild sugarcane clones originating from regions with high ambient UV-B (lower latitude or high elevation) were not necessarily the more tolerant to enhanced UV-B radiation.
