摘要：

本文对根构型的概念、根构型的研究方法及豆科作物根构型与磷效率的关系进行了论述.初步研究表明,豆科作物根构型的一些指标(根重、根长、根吸收面积等)与磷效率具有较好的相关性.建议拟合具有普遍意义的根构型综合指标,指导豆科作物磷效率遗传性状改良.

关键词: 根构型, 豆科作物, 磷效率

Abstract:

Abstract Root architecture is great importance to P uptake efficiency of leguminous crops. Some parametersof root architecture, such as root biomass, root length and root surface area, were found to be closely relatedto P uptake efficiency of common bean, soybean and Stylosanthes spp. In this paper, the concept and re-search methodology of root architecture were briefly reviewed in relation to the P uptake efficiency of someleguminous crops. It was suggested that integrated models of root architecture should be developed to pro-vide comprehensive yet realistic indices for effective genetic improvement of P efficlency of the crops.

Key words: Root architecture Leguminous crops P efficiency
