Effect of Plant Growth Promoting Rhizobacteria (PGPR) on Branching and Growing of Apple Sapling

According to the control, applications increased sapling height and this increasing was found important as statistically. Generally, bacteria applications more increase than Perlan on sapling height. Effect of bacteria and Perlan applications on sapling diameter showed different in cultivars and years. Generally, sapling diameter was increase by applications. Applications that on branching was important in 2009, but not important in 2010 as statistically. The most effective applications on branching were T8 and BA-8+T8 in 'Granny Smith', in 'Red Delicious, Red Chief' BA-8+T8 and BA-8, in 'Fuji' Perlan and BA-8 in 2009. Effect of applications on lateral branch degree was different in years and cultivars. According to the control, bacteria and Perlan applications raised length of lateral branch also bacteria was more effective than Perlan. Finally, plant growth promoting bacteria more increased branching and sapling quality than Perlan.
