降尘对核桃雌雄花生化特性的影响
Effects of Dust on the Biochemical Characteristics of Walnut Female and Male Flowers
摘要
Abstract
[Objective] To study the activities of SOD,POD,and the contents of MDA and proline in male and female flowers of walnut under different amounts of dust,the aim of this study is to investigate the effects of flowering dust on the biochemical characteristics of walnut flower organs,and deepen the understanding of the effect of dust on the flower organs of walnut in the southern Xinjiang basin.[Method]With Juglans regia'Wen185'as the experimental material,The control plant was set up by using the male and female artificial dustproof bagging and artificial simulation different levels of dust on the plants were used as the experimental treatments to analyze the effect of dust on male and female floral organ.[Result]Compared with the control,all the treatments of artificial simulation different levels of dust could increase the activities of SOD and POD and the content of proline in the male and female flowers.During the flowering of the female flowers,the difference of the activities of SOD and POD,and the contents of MDA and proline in all the treatments reached significant level(P<0.05)or extremely significant level(P<0.01).During the flowering of male flowers,the difference of the activity of SOD and POD,and the content of MDA and proline of all the treatments reached significant level(P<0.01),except the SOD and proline in male flowers at the beginning of flowering.[Conclusion]During the flowering of walnut,dust could increase the activity of SOD and POD and the content of proline and MDA in walnut male and female flower,thus adversely affecting the flower organs of walnut.关键词
