Abstract

In order to assess genotypic variability in some peanut genotypes depending on phosphorus availability, both effects of tri-calcium phosphate (TCP) and inoculation by Bradyrhizobium strain (BR) on morphological and physiological parameters were studied in five peanut genotypes (Arachis hypogaea L.), originated from two Algerian areas (Northern and Southern). The results obtained during the flowering stage of crop development, confirmed the positive effect of the contribution of tri-calcium phosphate (TCP) with Bradyrhizobium strains on the morphological characters (shoot biomass, root biomass, nodular biomass and leaf) and the physiological (nitrogenase activity, phosphorus absorption efficiency by roots (RPAE) and phosphorus use efficiency (PUE)) for the peanut genotypes cultivated in this experiment. Among five genotypes tested, it was noted that the Southern genotypes were more efficient to use TCP in the presence of Bradyrhizobium strain after a screening of these local genotypes, in particular, with phosphorus use efficiency (PUE) and shoot biomass production.

花生(arachhis hypogaea L.)磷生物利用度的基因型变异特征

为了评估某些花生基因型在磷有效性方面的基因型变异，研究了磷酸三钙(TCP)和接种慢生根瘤菌(BR)对阿尔及利亚北部和南部地区5种花生(arachhis hypogaea L.)形态和生理参数的影响。在作物发育开花期获得的结果证实了缓生根瘤菌对本试验栽培花生基因型的形态性状(茎部生物量、根部生物量、根瘤生物量和叶片生物量)和生理性状(氮酶活性、根吸收磷效率(RPAE)和磷利用效率(PUE))的积极影响。在5个基因型中，对南方基因型进行筛选后发现，南方基因型在缓生根瘤菌存在的情况下对TCP的利用效率更高，特别是在磷利用效率(PUE)和地上部生物量产量方面。
