Effect by Plant Growth Promoting Bacteria (Azospirillum halopraeferens and Klebsiella pneumoniae) on Lipid Value in Seed of the Halophyte Salicornia bigelovii Torr.

Abstract

Halophytes species appears on great scale as an alternative for the essential fatty acid production in human nutrition, for that reason, the fatty acid composition receives special importance. Salicornia bigelovii is a halophyte that developed in arid and coastal zones like Sonora State and the peninsula of South Baja California, Mexico. Salicornia could be an alternate species in the edible oil production. The similar fixation of N2 by bacteria associated with roots of Salicornia bigelovii and halophyte are an important nitrogen source available in coastal ecosystems. The inoculation of Klebsiellapneumoniae and Azospirillumhalopraeferens was evaluated during the vegetative development of Salicornia bigelovii under field conditions in two ecotypes (Cerro Prieto = CP and Santa Rosa = SR), having affected positively variable as weight, yields of production and biochemical characteristics and contained total of ashes, protein and total lipids in seed produced. Our results suggest that both ecotypes of S. bigelovii, under the conditions field used, can be improved with the application of K. pneumoniae and A. halopraeferens, showing a potential utility for agricultural producers of coastal semi-arid zones.
