摘要
用黑色遮阴网设置四种光强(全日照、全日照的33%、全日照的11%、全日照的3%),研究二月兰的耐阴性,结果表明:二月兰具有较典型阴生植物结构特点,其叶绿素含量随着光强降低而增加,叶绿素a/b则降低。二月兰对光照适应能力较强,全日照的3%下仍具有很高的观赏价值。但最适光照为全日照的33%。
In order to find the plant resources in the shade environment, Oryehophragmus violaeeus was selected as material of this experiment. Four light intensities ,fidl exposure, 33%,11%,3% of full exposure,were designed and provided with shading net in study. The results showed that Oryehophragmus violaeeus had the typical leaf cross section structure characteristics of shade-plant. The choropyU content increased with the increase of shade intensity, the value of ehoropyll a/b increased with the increase of exposure. Oryehophragmus violaeeus had a wide-range of light adaptahity to the low light intensity. The optimum light intensity was 33%of full exposure.
