Toplam 129 atıf DOI
Experiments were conducted during 2000 and 2001 to determine the effects of floral and foliar application of the bacterial strain Bacillus OSU 142 on the yield, growth and nutrient element composition of leaves of the apricot cultivar Hacihaliloglu grown in the Malatya province of Turkey. In 2000, trees were sprayed with a bacterial suspension at full bloom, and 30 and 60 days after full bloom. This experiment demonstrated significant differences in yield, shoot length and nutrient element composition of leaves only on trees treated at the full bloom stage. In view of this, the bacterial application was performed only at full bloom in 2001. The average increase in yield in 2000 and 2001 was 30% and 90%, respectively, compared with the untreated control Shoot length development was significantly higher when trees were treated with OSU 142 at full bloom stage in both years. Similarly, N, P, K, Ca and Mg contents of leaves were higher on OSU 142-treated trees than on the untreated control. The results of this study suggest that OSU 142 has the potential to increase the yield of apricot trees.

Sustainable Mitigation of Alkaline Stress in Grapevine Rootstocks (Vitis spp.) by Plant Growth-Promoting Rhizobacteria

Practical use of plant growth-promoting rhizobacteria (PGPR) on plants under stress conditions remains elusive because most of the studies focused on merely evaluating the plant growth-promoting effects on non-stressed plants. This study focused on the effect of root inoculation of different PGPRs on the growth and physiology of grapevine rootstocks 41 B, 99 R and 140 Ru grown in soilless culture with elevated pH. The rootstocks in pots under glasshouse condition were inoculated with Agrobacterium rubi A18 and Bacillus subtilis OSU 142 bacteria in early spring. To increase the pH of growth medium, the plants were watered with 250 mL plant−1 bicarbonate solution (840 g L−1 NaHCO3) four times (beginning at 3–4 cm shoot growth) with one-month interval during the vegetation. Along with the bicarbonate supplementation to growth medium, root rhizosphere pH increased from an initial value 7.76 to the final values between 8.10 and 8.26. Although the bacteria population decreased progressively, they were able to alleviate the negative effects of high pH by improving vegetative growth, leaf physiology and nutrient acquisition in many cases. The bacteria strains employed in this study can be recommended to support grapevine growth and physiology under alkaline conditions for a sustainable and environment-friendly viticulture.
