摘要
对金银木、榆叶梅、珍珠梅、红瑞木、连翘5种灌木绿化树种光合特性的研究比较结果表明:5种灌木树种的叶片生长,主要表现在叶片的加厚生长,叶面积的增大不占主要地位;因气温的变化光合特性在不同树种之间存在差异,随着气温降低,金银木、连翘的光合能力和光合潜力逐渐加强,而珍珠梅、榆叶梅、红瑞木则随着气温降低和光照减弱,其光合能力逐渐瓦解。
A comparative trial of photosynthetic characteristics of Amur honeysuckle（Lonicera maackii （Rupe.） Maxim.）, flowering almond （Prunus triloba Lindl.） , Sorbaria kirilowii , Comus alba L. and Forsythia suspeusa was carried out. The results showed that the growth of leaves of five shrub species, mainly in the thick growth of leaves, leaf area increase was not dominant. There was difference between tree species owing to changes of light and temperature. The lower the temperature, the strengthen the photosynthetic capacity and potentiality of Amur honeysuckle and Forsythia suspensa while with the temperature dropped and light became weaker, photosynthetic capacity of Sorbarie kirilowii, flowering almond and Comus alba L. gradually disintegrated.
