Abstract

The selection of N2 fixing bacteria is a dynamic process that can guarantee the supply of nitrogen needed for plant development. The selection of strains of rhizobia from the soil where it will be used in order to produce specific inoculants is a fundamental component for success in using this bio-feedstock. This study aimed to evaluate the competitive ability of strains isolated rhizobial native soils of semiarid. The isolated strains will be characterized for reaction (pH), evaluated the effects of inoculation on root phenotypes and subsequently stored. The characteristics evaluated were the increased number of root hairs, hairs curled, deformed, length and thickness of the main root and nodules on roots. The nodules that appeared more intense in seedlings with the isolates of number 259, 265, 266 and 283. The inoculant that had a higher competitive ability on the deformation, bending and increased number of root hairs were 251, 259, 263, 270, 284, 287 and 291. So, through the selection of efficient strains of rhizobia will be possible to produce forest seedlings nodulated well with faster growth and greater resistance to field conditions.
