【摘要】 本文探讨了5种室内观赏植物对不同光强的适应能力,以期为室内植物的选择提供科学合理的依据。本实验研究了5种室内观赏植物在全光照、透光率30%、15%、5%处理下的生长、生理及光合特性。结果表明:随着遮阴度的加强,植物的叶片数量、叶面积、株高增量、叶绿素含量及叶绿素b的相对含量增加;可溶性糖含量和POD活性值在最适光照环境下分别达到最高和最低;光合日变化曲线由双峰曲线变为单峰曲线,光补偿点逐渐降低。综合分析,豆瓣绿、白掌、鸟巢蕨对弱光适应能力强,最适合室内布置;发财树、金钱树具有较广的光适应范围,较强光或较弱光下都能良好的生长,但充足的光照更利于其生长,更适合布置在室内光线较充足的位置。更多还原

【Abstract】 For Discussing the ability of indoor plants to adapt to different light intensities,providing scientific and rational basis for the choice of indoor plants,in this paper choose 5 domestic ornamental plants as test material,observe their morphological characteristics,physiological characteristics,and photosynthetic characteristics under full exposure and 30 percent、15 percent、5 percent light transmittance.The results showed:along with the shading continue to strengthen,the plants’s leaf number, leaf area,height increment,chlorophyll,and the relative content of chlorophyll b increase.Under optimal light conditions soluble sugar content towards maximum and POD activity values towards minimum.With the strengthening of the shade degree, the daily changes of photosynthetic rate turned from double-peak curve to single-peak curve and light compensation point decreased. Comprehensively,Peperomia,White palm,Bird’s-nest fem are adapt to low hght and most suitable for the selection of indoor and landscape.Pachira and Money tree are have a wider light range,both good growth under high light,but also good growth in the weak hght But sufficient light is more conducive to their growth,more suitable arrangement in a room with sufficient light更多还原
