Abstract
The effects of clipping on the antioxidase activities and root morphogenesis of the floating seedlings of the main flue-cured tobacco varieties,Yun87,HongdaandK326,in Yunnan tobacco-growing area were studied by using spectrophotometry and scanning method respectively. The results indicated that: at the different developing stages of the seedlings,the clipping could all improve the catalase( CAT) activities ofK326,the peroxydase( POD) activities ofYun87andK326, and the superoxide dismutase( SOD) activities of Hongda; but for the CAT activities of Yun87 and Hongda,the POD activities of Hongdaand the SOD activities of Yun87and K326,the clipping displayed the increasing or decreasing effects. To a great extent,the clipping might change the correlation features of the main antioxidase activities of the floating seedlings of the three tobacco varieties along with the developing stage of the seedlings,and also exerted differential effects on the natures and degrees of the correlations of the root morphogenesis-related indexes,showing the most obvious effects onYun87,next wasK326,and the slightest onHongda. Therefore,the improving effects of the clipping on the antioxidase activities and the specific indexes of the root morphogenesis of the floating seedlings of Yun87,Hongdaand K326in Yunnan vary with the varieties,the developing stages of the seedlings and the specific indexes. This research could provide a theoretical basis for the reasonable application of the clipping in the floating seedling of the tobacco in Yunnan.
