红宝石海棠叶片花青素及叶绿素含量的影响因子

对红宝石海棠树体不同部位叶片的花青素和叶绿素含量进行了测定,并对其夏秋两季的动态变化进行了研究。结果表明:随着时间的变化,气温逐渐降低,上位叶与下位叶均表现出花青素含量上升而叶绿素含量下降的变化趋势;在相同时期内,花青素含量均表现为上位叶显著大于下位叶,而叶绿素含量恰恰相反。花青素的形成与叶绿素呈显著负相关,温度和光照均是影响花青素合成的重要因素。

Affecting Factors of Contents of Anthocyanin and Chlorophyll in leaves of Malus spectabilis Royalty

The contents of anthocyanin and chlorophyll in leaves from different positions of Malus spetabilis Royalty were determined,and its' dynamic changes in summer and autumn were analyzed. The results indicated that the contents of anthocyanin in the leaves from the upper and lower positions were both increased with season changing and temperature decreased, while the contents of chlorophyll were both decreased at the same condition;the contents of anthocyanin in the leaves from the upper position were significant higher than that from the lower position in the same stages, while the contents of chlorophyll were just contrary to that of anthocyanin. Content of anthocyanin had a significant negative relation with that of chlorophyll,and temperature and light were the major affecting factors of anthocyanin synthesis.
