查询词典 slash pine

Applied with test of potted plant and measurement absorbency for study response of the contents of photosynthetic pigments of slash pine's half-sib under water stress. There are 7 families comparison with general slash pine. The contents of photosynthetic pigments are mensurated under feebleness water stress while soil water content is 55% to 60% and moderate water stress while soil water content is 35% to 40% and heavy water stress while soil water content is 20% to 25%. The test result indicate that either water grads or families of chlorophyll and chlorophyll a and chlorophyll b and Chla/Chlb and carotenoid and Caro/Chl are mighty notable difference. The Chl and Chla and Chlb and Chla/Chlb little drop from normal soil water to initial water stress. Then drop obvious with increased water stress. The Caro and Caro/Chl little drop firstly from normal soil water to initial water stress,then up in metaphase water stress,after drop in evening water stress. The Chl and Chla and Chlb and Chla/Chlb and Caro of slash pine'half-sib are over general slash pine. The Chl and Chla and Chlb and Chla/Chlb and Caro of 464 and 1027 are over average value of slash pine's half-sib under water stress. The Caro/Chl of 609 and 46 are over average value of slash pine's half-sib under water stress.
