摘要
园林植物抗旱性的评价主要以形态评价、生理生化评价和生态适应性评价为主。随着色彩量化研究方法在各个学科的广泛应用,园林植物受干旱胁迫后叶色的变化将会成为表征树种抗旱特征的重要指标。在对10种园林引进树种抗旱胁迫试验的基础上,从叶片色相、饱和度、亮度三个维度对叶片颜色进行量化分析。结果显示:苏格兰金链树、红火箭紫薇、刺槐、加拿大紫荆四种树种在干旱胁迫下叶色变化较大,该方法为科学选择干旱生境园林树种提供了新的对策。
The drought resistance evaluation of landscape plants mainly includes morphological,physiological and biochemical,as well as ecological adaptability index traditionally.With the wide application of color quantification in various subjects,the change of leaf color of landscape plants subjected to drought stress will become an important index of drought resistance analysis.On the basis of drought stress test for 10 introduced tree species,the quantitatively analyzed the leaf color was carried out from three dimensions of hue,saturation and brightness.It was found that the leaf color of Laburnum alpinum,Lagerstroemia indica‘Red Rocket’,Robinia pseudoacacia and Cercis canadensis had a great change under drought stress.It provides innovative countermeasures for scientific selection of landscape tree species in arid habitats.
