| 摘 要： | 以水稻为材料,通过对叶绿素含量、过氧化物酶(POD)活性、丙二醛(MPA)、相对电导率(REC)和光合速率的测定,研究了UV-B胁迫下芦荟蒽醌类物质对水稻生长发育的影响。结果表明,用质量浓度为1 mg/L和10 mg/L的芦荟蒽醌类物质喷施水稻,水稻叶绿素含量分别提高了24.5%和17.8%,POD活性分别上升12.4%和29.4%,MDA含量分别降低了50.5%和21.9%,水稻叶片REC有所下降,而净光合速率均有所提高。说明喷施芦荟蒽醌类物质能有效减轻UV-B辐射对水稻的损伤。

| Abstract: | The physiological indexes of rice(Oryza sativa L.) under enhanced UV-B radiation stress were measured,to study the effects of aloe's anthraquinones on its growth.The results showed that UV-B radiation affected the growth of plants significantly.The chlorophyll contents of the rice sprayed with anthraquinones of 1mg/L and 10mg/L were increased by 24.5% and 17.8%,the POD activities were increased by 12.4% and 29.4%,and the contents of MDA were decreased by 50.5% and 21.9%,respectively,compared with that sprayed only with water.The REC of the anthraquinones-treated rice was reduced,and net photosynthesis rate was increased.Therefore the harm of UV-B radiation to plants could be reduced effectively by spraying aloe's anthraquinones on plant surface. |
