Abstract
The changes of the content of chloroplast pigment and taxol in the leaves of Taxus chinensis var.mairei were studied with light stress.The results comparing with the comparison showed that the contents of chlorophyll-a,chlorophyll-b and chlorophyll and the ratio of chlorophyll-a to chlorophyll-b were lower.However,the contents of chlorophyll-a,chlorophyll-b and chlorophyll tended to gradually rise as the stress prolonged,but the ratio of chlorophyll-a to chlorophyll-b first rose and then decreased.The content of carotenoid was lower than the comparison in the first two weeks and then surpassed the comparison.The ratio of carotenoid to chlorophyll was higher than the comparison and tended to first decreased and then rose as the stress prolonged.The contents of taxol was slightly lower than the comparison in the first week and then begun to gradually accumulate in the leaves of Taxus chinensis var.mairei at the second week,the content of taxol had increased to 1.5 times of the comparison at the third week,which is very significant to improve the content of taxol in the growed Taxus chinensis var.mairei.
