Change Rule of Pigment Content in Different Color Systems of Sapium sebiferum in Color Stage
摘要
Abstract
The study aims to provide a theoretical basis for the study of the coloration mechanism of Sapium sebiferum and its configuration in garden applications.During the color-changing period of S.sebiferum leaves,physiological indexes such as chlorophyll,carotenoid and anthocyanin in different color systems of red,yellow and purple were measured regularly,the changing trend of pigment content in different color systems was compared,and the correlation between each pigment content and temperature change was analyzed.The results showed that the contents of chlorophyll a and chlorophyll b in red,yellow and purple S.sebiferum showed a decreasing trend,and the contents of chlorophyll a,chlorophyll b and carotenoid in purple were higher than those in other colors.Low temperature had little effect on the formation of yellow anthocyanins,but accelerated the formation of purple and red anthocyanins,and the increase of its content was conducive to the color of purple and red S.sebifeerum leaves.Although soluble sugar did not directly affect the change of leaf color,it could indirectly regulate the change of leaf color parameters such as chlorophyll.关键词
