Abstract: (4745 Views)
A greenhouse experiment was conducted at Agricultural Biotechnology Research Institute, Central Region of Iran to evaluate the effects of some plant growth promoting bacteria and fungi inoculation on growth and minituber yield of potato cultivars. The experiment was arranged as a factorial based on a completely randomized design with ten replications. Three potatoes (Solanum tuberosum L.) genotypes (Agria, Marfona and Aranda) were treated by eleven biological treatments including bacillus, azotobacter, pseudomonas, glomus, combination of bacillus + glomus, pseudomonas + glomus, azotobacter + glomus, azotobacter + bacillus, azotobacter + pseudomonas, azotobacter + bacillus + glomus, and azotobacter + pseudomonas + glomus during vegetative stage. Analysis of variance results indicated that the effects of biological treatments on number of minituber, yield, and total dry weight of minituber were significant at 1% probability level. But there was not any significant difference in terms of size and weight of each minituber. The interaction of biological treatments and genotypes was also significant for yield and total dry weight of minituber. The highest tuber yield and total dry weight were observed for the Aranda genotype treated with azotobacter + pseudomonas + glomus. Moreover, the results revealed that azotobacter + glomus and azotobacter had the highest plant height and number of lateral shoot, respectively, as compared to other treatments.
