The effects of plant growth promoting rhizobacteria (PGPR) on the rooting and root growth of semi-hardwood and hardwood kiwifruit stem cuttings were investigated. The PGPR used were Bacillus RC23, Paenibacillus polymyxa RC05, Bacillus subtilis OSU142, Bacillus RC03, Comamonas acidovorans RC41, Bacillus megaterium RC01 and Bacillus simplex RC19. All the bacteria showed indole-3-acetic acid (IAA) producing capacity. Among the PGPR used, the highest rooting ratios were obtained at 47.50% for semi-hardwood stem cuttings from Bacillus RC03 and Bacillus simplex RC19 treatments and 42.50% for hardwood stem cuttings from Bacillus RC03. As well, Comamonas acidovorans RC41 inoculations indicated higher value than control treatments. The results suggest that these PGPR can be used in organic nursery material production and point to the feasibility of synthetic auxin (IBA) replacement by organic management based on PGPR.
研究了植物促生根际细菌（PGPR）对半硬木和硬木猕猴桃茎段生根和根系生长的影响。使用的 PGPR 有 RC23 芽孢杆菌、多粘类芽孢杆菌 RC05、枯草芽孢杆菌 OSU142、RC03 芽孢杆菌、食酸丛毛单胞菌 RC41、巨大芽孢杆菌 RC01 和简单芽孢杆菌 RC19。所有细菌均具有产生吲哚-3-乙酸（IAA）的能力。在使用的 PGPR 中，RC03 芽孢杆菌和 RC19 简单芽孢杆菌对半硬木茎段的生根率最高，达到 47.50%，RC03 芽孢杆菌对硬木茎段的生根率最高，达到 42.50%。此外，食酸丛毛单胞菌 RC41 的接种表明比对照处理具有更高的价值。结果表明，这些 PGPR 可用于有机苗圃材料的生产，并指出基于 PGPR 的有机管理可以替代合成生长素（IBA）。
