抗氧化酶对棕色棉色泽的影响
Effect of Antioxidases on Color of Brown Cotton
摘要
Abstract
Brown and white cotton cultivars were used as materials, the change of the content of related substances to pigment synthesis and the activities of antioxidases both in the fiber and the seed capsule during the development were investigated, and the effect of antioxidases on color of brown cotton was studied. The results indicated that the color of the seed capsule darkened apparently during the secondary cell wall thickening period（25～45 DPA）;the color of the fiber darkened obviously during the secondary cell wall thickening period（35～45 DPA）.The content of condensed tannin and the phenol in the seed capsule of light brown ANL-2 decreased and pigments accumulated from 28 to 35 DPA; the content of condensed tannin in the fiber of dark brown ANL-1 decreased ,while the content of the phenol increased ,and the color of the fiber became darkest from 35 to 42 DPA. The activity of POD in the seed capsule of light brown ANL-2 from 28 to 35 DPA decreased, and the activity of POD in the fiber of brown cotton decreased from 35 to 42 DPA; the effect of SOD and CAT on color of brown cotton was small. POD participated in the formation of pigments during the secondary cell wall thickening period（35～45 DPA）.关键词
