Implications of the Symbiotic Nitrogen Fixation in Common Bean under Seasonal Water Stress

摘要: The objective of this research was to study the performance 10 common bean genotypes under water deficit stress and how it affects their symbiotic relationship with Rhizobium strains in both greenhouse field conditions. PHA-0471, a small seeded genotype had best yield irrigation stress. Other tolerance drought were large-seeded PHA-0432 PHA-0683. In inoculation tests observed that increase dry nodular weight produced less seed beans. PHA-0683 presented great uniformity on nodule size an association when displays big phenotype. Further about would be interesting because fact could due existence plant blocking mechanism for inefficient strain nodules. inoculated plants productive irrigated fields ones productivity same or even better than N supplemented control. genotype-strain very specific local achieved greatest some conditions make possible use as inoculating strains, relevance environmental impact agriculture.
