摘要

本研究评估了产抗生素的绿绿假单胞菌菌株提高马铃薯产量和抑制马铃薯植物病原真菌尖孢镰刀菌(Fo)菌丝生长的潜力。青霉亚种aurantiaca菌株Q16 (PchlQ16)对FoA2分离物的体外生长抑制率最高(67.07%)。在田间试验中,PchlQ16对鲁道夫马铃薯品种的茎数、块茎数和块茎重量以及马铃薯总产量的影响进行了测定。施用青霉量和处理次数对产量有显著影响。PchlQ16 2个处理的块茎总产量较对照提高4.9% ~ 33.05%,4个处理的块茎总产量较对照提高9.3% ~ 92.35%。根据田间试验结果,建议在马铃薯生长季节频繁施用PchlQ16(4次)。我们的体外实验结果支持这些发现,因为该菌株抑制了尖孢镰刀菌的生长。本研究证实PchlQ16在马铃薯生产中是一种有效的促生长剂,对尖孢镰刀菌侵染有较好的预防作用。

The effect of Pseudomonas chlororaphis subsp. aurantiaca strain Q16 able to inhibit Fusarium oxysporum growth on potato yield
This study assesses the potential of antibiotics-producing Pseudomonas chlororaphis strains to increase potato yield and to inhibit the mycelial growth of phytopathogenic fungi Fusarium oxysporum (Fo) isolated from potato. P. chlororaphis subsp. aurantiaca strain Q16 (PchlQ16) caused the highest growth inhibition (67.07%) of FoA2 isolate in vitro. In field trials the effect of PchlQ16 was measured as the number of stems, number and weight of tubers and a total potato yield of the Rudolph potato variety. Application of P. chlororaphis and the number of treatments exhibited a significant effect on the yield. Two treatments of PchlQ16 increased the total yield of tubers from 4.9% to 33.05%, while four treatments from 9.3% to 92.35%, compared to the control. Based on our field results we can recommend a frequent application of PchlQ16 (4 times) during potato growth season. The results of our in vitro experiment support these findings as the bacterial strain suppressed growth of F. oxysporum. In this investigation PchlQ16 was confirmed as an effective growth promoting agent in potato production and can be highly effective in prevention of F. oxysporum infection.
