Enhancement of seed germination and seedling vigor of wheat (Triticum aestivum L.) following PGPR treatments
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2014, Vol 1, Issue 3
Abstract
Abstract: Uses of bio-fertilizers containing beneficial microorganisms instead of synthetic chemicals are known to improve plant growth through supply of plant nutrients. In order to investigated the effects of plant growth promoting rhizobacteria (PGPR) on improvement of seed germination and seedling vigor of wheat cultivars an experiment was conducted at the research laboratory of Genetics and Agricultural Biotechnology Institute of Tabarestan, Sari Agricultural Sciences and Natural Resources University (SANRU), during the 2013. In this study, a factorial experiment based a completely randomized block design with three replications was used. This experiment had two factors, the first factor with five levels of wheat cultivars (Shanghi, Zaghros, Milan and Tajan). In the second factor, four levels of rhizobacteria were treatment: single and co-inoculation Azospirillum lipoferum, Azotobacter chroococcum. Results showed that, Seed inoculation of PGPR strains significantly increased germination rate, and root length of wheat compared with the control. In addition, seedling vigor index was investigated and significantly affected by bacterial applications compared with the control. The results of this study suggest that Azospirillum lipoferum and Azotobacter chroococcum in combination have the potential to increase the growth and development of wheat cultivars. Keywords: Germination, Priming, Seedling vigor, PGPR.
