研究了干旱胁迫条件下磷酸溶菌（PSB）对番茄种子的催熟效果。使用磷酸盐增溶菌作为接种剂，可同时增加植物对磷的吸收和作物产量。由于喀拉拉邦的农民严重受够了夏季普遍存在的缺水状况，目前的尝试可能只是向他们伸出援助之手的一小步。在研究中，番茄（L. esculentum）的种子cv。用0.5%和1%的磷酸盐增溶菌进行预处理。对发芽率、根长、茎长、相对含水量、叶绿素含量、蛋白质含量、脯氨酸含量、产量等进行了研究。接种增磷菌对番茄植株的生理生化指标有显著影响。在两种测试浓度中，发现0.5%的磷酸盐增溶菌可以有效减轻水的影响
The main aim of the present investigation is to evaluate the effect of priming of seeds of tomato (Lycopersicon esculentum) with phosphate solubilising bacteria (PSB) during drought stress condition. The use of phosphate solubilising bacteria as inoculants is found to be simultaneously increasing the Phosphorus uptake by the plant and crop yield. As the farmers in the state of Kerala are severely fed up with the water stress condition prevailing in the summer season, the present attempt may become miniature step to stretch a helping hand to them. In the study, the seeds of tomato (L. esculentum) cv. Anakha were subjected to priming treatment with 0.5 % and 1% phosphate solubilising bacteria. The parameters like germination percentage, root length, shoot length, relative water content, amount of chlorophyll, protein, proline and yield were studied. Inoculation with phosphate solubilising bacteria showed remarkable variation in both physiological and biochemical parameters of tomato plants. Among the two concentrations tested, 0.5% phosphate solubilising bacteria was found to be effective in mitigating the effect of water
