不同光质和光照强度对多肉植物蒂亚叶片呈色的影响

Effect of Different Light Quality and Intensity on the Leaves’Color of Succulent Plants Edeveria Letizia

本文通过覆盖不同层数的遮阴网及利用红光、蓝光、白光、自然光四种不同光源营造出不同的光照强度和光质条件,测定其内蒂亚叶片花青素、叶绿素含量,观察蒂亚叶片颜色变化情况,探讨光质和光照强度对蒂亚呈色的影响。结果表明,四种光源处理后,蓝光条件下蒂亚叶片叶绿素和花青素明显变化。与自然光相比,蓝光条件下蒂亚叶片花青素含量最多,颜色变化最为明显,蒂亚叶片颜色大多由绿色变为红色;红光比蓝光对蒂亚叶片颜色影响稍弱,自然光对蒂亚叶片颜色影响最弱,蒂亚叶片颜色变化最小的是白光。光照强度对蒂亚叶片呈色的影响明显,随光照强度的增大,蒂亚叶片中花青素含量随之增加,颜色由绿色转变为红色占比加大。但随着光照强度的增大,蒂亚叶片会出现灼烧现象。光照强度和光质对蒂亚叶绿素和花青素的影响与对表观颜色变化的影响一致。因此在蒂亚种植过程中,可选择1层遮阴网遮阴,使用蓝光照射。本文为得出适合蒂亚颜色变化的光质和光照强度,提高蒂亚的观赏价值和经济价值提供了理论依据。

In order to explore the effect of different light quality and light intensity on the color of Tia leaves,the light quality and light intensity suitable for Tia color change were obtained,and the ornamental value and economic value of Tia were improved.By covering different layers of shading net and using four different light sources-red light,blue light,white light and natural light-to create different light intensity and light quality conditions,the contents of Netia anthocyanin,chlorophyll and the color changes of Tia leaves were determined.The results showed that the color of Tia leaves was the best and the growth was good when they were covered with a layer of sunshade and the shading net were red and green.Without shading net,the color was mostly red,less green with better color and burning phenomenon.In the light quality experimental group,the red light had a great influence on the color of Tia leaves,the red color of leaves was the majority in the red light environment followed by the red light.The white light had little effect on the color change and the color change was not particularly obvious.
