During 2003 and 2005, plant growth promoting effects of Pseudomonas BA-8 and Bacillus OSU-142 were tested alone or combinations on sweet cherry (Prunus avium L.) cv. 0900 Ziraat in terms of yield, growth, nutrient composition of leaves in the province of Konya, Turkey. The presence of Pseudomonas BA-8, Bacillus OSU-142 and BA-8 + OSU-142 stimulated plant growth and resulted in significant yield increase. Floral and foliar applications of BA-8, OSU-142 and BA-8 + OSU-142 in sweet cherry significantly increased yield per trunk cross-sectional area (16.3, 10.9 and 21.7%), fruit weight (4.15, 5.37 and 1.24%) and shoot length (11.3, 11.8 and 29.6%), respectively, compared with the control. In addition, N, P and K contents of sweet cherry leaves with BA-8, OSU-142 and BA-8 + OSU-142 treatments, Fe and Zn contents of leaves with BA-8 + OSU-142 treatment and Mn content of the leaves of sweet cherry with BA-8 and OSU-142 applications significantly increased. Nitrogen, P and K contents in leaves were determined to be increased from 2.00, 0.17 and 0.43% in the control to 2.19, 0.20 and 0.54% by BA-8 application, to 2.32, 0.24 and 0.54% by OSU-142 application and to 2.43, 0.22 and 0.51% by BA-8 + OSU-142 application, respectively. Co-inoculation of BA-8 + OSU-142 increased Fe and Zn contents of leaves up to 50.5 and 35.5% compared with the control, respectively. Manganese content of leaves significantly also increased by BA-8 (26.6%) and OSU-142 (27.0%) applications compared with the control. The results of the present study suggested that Pseudomonas BA-8 and Bacillus OSU-142 alone or in combination have a great potential to increase the yield, growth and nutrition of sweet cherry plant. © 2006 Elsevier B.V.

During 2006 and 2007, fruit thinning effects of three plant growth promoting rhizobacteria (PGPB) strains (Bacillus OSU-142, Microbacterium R23 and Bacillus T7) and NAA (10 and 20 ppm) were tested in apple cvs. Golden Delicious and Braeburn in terms of fruit setting, yield, fruit weight, fruit firmness, total soluble solid (TSS), titratable acidity and shoot length in the province of Konya, Turkey. Bacterial strains were sprayed at 7, 14 and 21 days after full bloom, and NAA was sprayed at 21 days after full bloom. The results showed that NAA and bacterial treatments decreased fruit setting and number of fruit per tree at various ratios in both cultivars. The lowest fruit setting cvs. Golden Delicious and Braeburn were obtained from 20 ppm NAA treatment in both years. Among the bacterial treatments R23 (24.1% in 2006 and 39.1% in 2007) in Golden Delicious and R23 (11.6% in 2006) and T7 (17.3% in 2007) in Braeburn gave the lowest fruit setting ratio while fruit setting ratio in Golden Delicious and Braeburn were 36.7 and 46.2% (2006) and 12.8 and 28.2% (2007) in the control, respectively. The highest fruit number was found from the control in both cultivars and years. Fruit yield was significantly decreased in Golden Delicious by NAA treatments but not affected in Braeburn by thinning. The highest yield was found from the control in cvs. Golden Delicious and Braeburn in both years. However, fruit weight was significantly increased by NAA and bacterial treatments. While the lowest fruit weight was in the control in both cultivars and years, the highest fruit weight was in R23 in Golden Delicious (164.6 g in 2006) and T7 (138.7 g in 2006) and OSU-142 (173.5 g in 2007) treatments in Braeburn. Treatments of R23 and T7 significantly increased fruit firmness in Golden Delicious and Braeburn in both years, respectively compared with the control. NAA and bacterial applications also significantly increased TSS in Braeburn but not Golden Delicious. The results of this study suggest that Bacillus OSU-142, Microbacterium R23 and Bacillus T7 have the potential to be used as fruit thinning agents under organic and sustainable growing conditions on apple. © 2009 Taylor & Francis Group, LLC.
