Abstract

Abstract The lisianthus culture is demanded to produce cut flowers and pot vases, grown in a greenhouse using advanced techniques. The present study aimed to evaluate the pigments of different lisianthus cultivars in different photoselective shade nets. The cultivars Flare Deep Rose (pink), Echo Blue BL (purple) and Allemande White BI (white) were cultivated under light-diffusing polyethylene film cover and blue and red color photoselective nets with a shading capacity of 30%, in addition to the control treatment, without the use of the net. The results showed higher values of chlorophyll b and total in the red photoselective net, independent of the cultivar. Leaf colorimetry showed the most intense shade of green was from the cultivar Echo Blue BL. On the other hand, the control showed more intensity, with no significant difference in the leaf green intensity on the blue and red shade nets. In the petals, the cultivar Echo Blue BL showed a more intense blue shade in the red net, however low grade of anthocyanin than in the blue one. In the anthocyanin pigment, this cultivar had lower levels in the treatment of the red net. The results indicate that the use of photoselective shade nets in the culture of lisianthus changes the content of the pigments studied, in varying intensity, depending on the cultivar.

不同光选择遮荫网对桔梗花茎色素的影响

摘要:在温室中采用先进的栽培技术，对万寿菊的栽培要求是生产切花和花盆。本研究的目的是评价不同品种的百叶菊在不同光选择性遮荫网下的色素。在对照处理的基础上，采用散光聚乙烯膜覆盖和遮光能力为30%的蓝、红两色光选择网，在不使用网的情况下，培育出粉红色的Flare Deep Rose、紫色的Echo Blue BL和白色的Allemande White BI。结果表明，红色光选择网中叶绿素b和总含量较高，与品种无关。叶片比色分析结果显示，回声蓝BL的绿光强度最大，而对照的绿光强度更大，在蓝网和红网上的绿光强度差异不显著。在花瓣中，回声蓝BL在红色网中呈现出更强烈的蓝色阴影，但花青素含量低于蓝色网。在花青素色素方面，该品种在红网处理中含量较低。结果表明，光选择遮荫网的使用改变了所研究的色素含量，其强度取决于品种。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
