Seasonal Dynamic of the Yield of Taxol in the Branches and Leaves of Taxus chinensis var. mairei with Different Shade Intensities
摘要
Abstract
Seasonal dynamic of the yield of taxol in the branches and leaves of Taxus chinensis var. mairei with different shade intensities in one growth season was studied. The season change law of the biomass, the content and yield of taxol in the branches and leaves of T. chinensis var. mairei showed distinct seasonal change. The biomass of taxol in the branches and leaves of T. chinensis var. mairei shaded with shade net of 89% shade degree was higher than that shaded with shade net of 46. 4% shade degree. The content of taxol in the branches and leaves of T. chinensis var. mairei shaded with shade net of 89% and 46. 4% shade degree respectively, both showed higher value in May, July and November, but the higher value of 46. 4% shade degree was obviously higher than that of 89% in the same period. The periods of the highest yield of taxol in the branches and leaves of T. chinensis var. mairei in one growth season are both November, but the highest yield of 46.4% shade degree was obviously higher than that of 89% . Therefore, we can choose the shade degree of 46. 4% in the practical produce and the best harvest season is November.关键词
