Abstract

Low phosphorus (P) availability is a major constraint for chickpea production. Consequently, P-efficient genotypes can improve productivity under conditions where the higher application of P is not economical. This study was conducted to characterise four chickpea genotypes for nutrient uptake and use efficiency under low-P conditions over two growing seasons. At flowering stage, plants were harvested and analysed for their nodulation, growth, P content and yield. Results indicate that low P availability significantly limited plant growth, nodulation and yield for all genotypes with the greatest effect on for Flip 84-92C and Flip 01-29C. The genotypes Flip 90-13C and ILC 32-79 showed the highest P uptake and use efficiency. The genotypes with high nutrient uptake had better efficiency in use of rhizobial symbiosis. It is concluded that nutrient uptake and use efficiency may be an important functional trait that may contribute to the selection of cultivars able to produce high quality seeds and efficiently fix nitrogen under conditions of low soil P.

地中海气候低磷条件下鹰嘴豆营养吸收和利用效率的基因型变异

低磷有效性是鹰嘴豆生产的主要制约因素。因此，高效磷基因型可以在高磷施用不经济的条件下提高生产力。本研究对四种鹰嘴豆基因型在两个生长季节的低磷条件下的养分吸收和利用效率进行了表征。在开花期，对植物进行收割，并对其结瘤、生长、磷含量和产量进行分析。结果表明，低磷有效性显著限制了所有基因型的植物生长、结瘤和产量，对Flip 84-92C和Flip 01-29C的影响最大。基因型Flip 90-13C和ILC 32-79表现出最高的磷吸收和利用效率。养分吸收率高的基因型利用根瘤菌共生效果较好。结果表明，养分吸收和利用效率可能是一个重要的功能性状，有助于在低土壤磷条件下选择能够生产优质种子和有效固定氮的品种。
