| 摘 要： | 目的]从生理生化角度揭示不同光质处理对枫香家系叶色变化的影响,为探索枫香叶色对光质的响应机理提供参考。方法]以2个枫香家系的1年生幼苗为试验材料,测定其在不同光质处理下叶片叶绿素、类胡萝卜素、花青素、可溶性糖、类黄酮和苯丙氨酸解氨酶的含量并分析其相关性。结果]结果表明:试验后2个枫香家系叶色较处理前有一定程度的变化。红光处理组枫香幼苗叶片叶绿素含量显著高于其它处理组,而蓝光处理组叶片叶绿素含量则显著低于其它处理组。蓝光处理后,2个枫香家系叶片花青素含量较对照有显著提高,而红光处理则减少了叶片花青素含量。同时蓝光处理能显著提高枫香幼苗叶片类胡萝卜素、可溶性糖和类黄酮含量以及苯丙氨酸解氨酶活力,红光处理效果较对照无显著差异。方差分析表明,不同光质处理对枫香幼苗叶片叶绿素含量影响显著,而对花青素量和类胡萝卜素含量影响不显著。结论]2个枫香家系叶色在光质处理下有相同的变化趋势,红光处理可以促进枫香幼苗叶片叶绿素合成;蓝光处理可以促进枫香幼苗叶片积累更多的花青素。

| Abstract: | Objective] To investigate the physiological and biochemical mechanisms of leaf colorization of two Liquidambar formosana families under different light quality to provide reference for exploring the response of leaf color to light quality.Method] The change of the chlorophyll, carotenoid, anthocyanin, soluble sugar, flavonoid and phenylalanine ammonia-lyase (PAL) contents in L. formosana leaves were assessed. The relationship among all indexes was also discussed.Result] The leaf color of L. formosana was slightly changed from green to red or dark red during the experiment. In addition, the change of leaf color of the 2 L. formosana families showed difference. The content of chlorophyll of L. formosana in the red light treatment group was significantly higher than that in other treatment groups, while the chlorophyll content in the blue light treatment group was significantly lower compared with that in other treatment groups. The contents of anthocyanin of the 2 L. formosana families were significantly improved under blue light treatment, while the contrary trend was observed in red treatment. At the same time, blue light treatment significantly increased the contents of carotenoid, soluble sugar and flavonoids and phenylalanine ammonia enzyme activity. Variance analysis indicated that different light treatments had significant effects on the content of chlorophyll within the L. formosana leaves, while the effects on the concentration of anthocyanin and carotenoid were indistinctive.Conclusion] The change of leaf color of the 2 L. formosana families shows the same trend under the different spectrum light treatments, the red light treatment can promote the synthesis of chlorophyll; however, the concentration of anthocyanin in blue light treatment is higher than that in other spectrum light treatments. |
