- 摘要:
- 以银杏‘黄金万两’为试材，‘夏金’为对照（CK），在对叶形、叶色观察的基础上，采用X-Rite色差仪测定叶色参数L*、a*、b*值，测定其叶绿素、类胡萝卜素组分以及主要代谢物含量，并研究叶色变化及光响应特征对2个银杏品种的影响，以期为培育出优质的金色叶银杏新品种提供参考依据。结果表明：‘黄金万两’叶形主要以心形为主，叶片没有烂叶现象，叶色3月豆绿色，4月黄绿色，5月黄色，6—10月分别为豆绿-褐绿-褐绿-油绿-褐绿，11月金黄色，而CK叶形主要以扇形为主，叶片在5月底6月初有一次明显的烂叶过程，叶色3月黄色，4月黄色，5月金黄色，6—10月分别为金黄-柳绿-褐绿-褐绿-柳绿，11月呈黄色。色素含量年变化中，‘黄金万两’总叶绿素、叶绿素a、叶绿素b含量均显著高于CK，而且在不同光照强度下‘黄金万两’最大光合速率显著高于CK，说明‘黄金万两’的光合能力更强。
- Abstract:
- Taking Ginkgo biloba ‘HL’ as the test material，‘XJ’ as the control (CK)，based on the observation of leaf shape and color，the values of L*，a* and b* of leaf color parameters and the contents of chlorophyll，carotenoid components and main metabolites were determined by X-Rite colorimeter，and the effects of leaf color changes and light response characteristics on two G.biloba varieties were studied,in order to provide reference for breeding new varieties of golden G.biloba with high quality.The results showed that,the leaf shape of ‘HL’ was mainly heart-shaped，and there was no rotting leaf phenomenon in the leaves.The leaf color was bean-green in March，yellow-green in April，yellow in May，bean-green，brownish-green，brownish-green，greasy-green，brownish-green from June to October，respectively，and golden in November，while the leaf shape of CK was mainly fan shaped，and the leaves had an obvious rotting process in late May and early June，and the leaf color was yellow in March and April.Golden in May，golden，willow-green，brownish-green，brownish-green，willow-green from June to October，yellow in November.In the annual change of pigment content，the chlorophyll a，chlorophyll b and total chlorophyll contents of ‘HL’ were significantly higher than CK，and the maximum photosynthetic rate of ‘HL’ was significantly higher than that of the CK under different light intensity，indicating that ‘HL’ had stronger photosynthetic capacity.
