Abstract

ABSTRACT We screened four strains (Burkholderia sp. St-A, and Pseudomonas spp. St-B, St-C, and St-D) from 21 bacterial isolates isolated tomato cultivation fields based on their plant growth-promoting traits. Then, tomato (‘Micro-Tom’) seedlings inoculated with each of the four selected strains were grown under non-salinity and salinity (NaCl) treatment conditions. Under non-salinity conditions, St-C and St-D strains increased the total biomass of roots, stems, and leaves and fruit yield. Under NaCl treatment conditions, St-B, St-C, and St-D strains increased total biomass and fruit yield. In roots, Na content was not suppressed, but K, P, and water content were increased by bacterial inoculations. Correlation analysis showed a significant and positive relationship between fruit yield and root under both non-salinity and salinity conditions. This indicates that the maintenance of homeostasis and water relations in roots may contribute to the improvement of plant growth, including root and fruit yield, under salinity conditions.

盐度条件下接种伯克霍尔德菌和假单胞菌对番茄“微汤姆”生长、产量和无机成分吸收的影响

摘要根据番茄生长促进特性，从番茄栽培区分离的21个菌株中筛选出4个菌株（伯克霍尔德菌St-A和假单胞菌St-B、St-C和St-D）。然后，用四个选定菌株中的每一个接种番茄（“Micro-Tom”）幼苗在无盐和盐度（NaCl）处理条件下生长。在无盐条件下，St-C和St-D菌株增加了根、茎、叶的总生物量和果实产量。在NaCl处理条件下，St-B、St-C和St-D菌株提高了总生物量和果实产量。在根中，细菌接种没有抑制Na含量，但增加了K、P和水分含量。相关分析表明，在无盐和无盐条件下，果实产量与根系均呈显著正相关。这表明，在盐度条件下，维持根系的稳态和水分关系可能有助于改善植物生长，包括根系和果实产量。
