背景:草莓(Fragaria×ananassaDuch。)is,在小水果中,葡萄牙种植和商业化程度最高。最近的研究证明了植物生长促进细菌(PGPB)接种对草莓生产的积极影响,同时,提供了一种减少肥料使用的替代策略。在这项研究中,用三种PGPB菌株(Pedobactersp。CC1,萨博芽孢杆菌B106和枯草芽孢杆菌B167A)对生理,增长,草莓cv的水果产量和质量。Camarosa被介绍。
结果:接种PGPB显著加速作物成熟,接种的植物比未接种的植物提前约2周结果。用马杆菌属接种植物。CC1和萨氏芽孢杆菌B106影响草莓植株的气体交换参数。发现Pedobactersp的草莓叶中总酚和类黄酮的含量更高。与未接种的植物相比时,CC1。此外,接种相同细菌菌株的植物显示出果实尺寸的增强,尤其是水果长度,和形状以及总可溶性固体含量(°Brix)。
结论:结果表明,PGPBPedobactersp。CC1提高了草莓植株的性能,这表明它可能是草莓植物营养的潜在生物肥料。©2019化学工业学会。
BACKGROUND: The strawberry (Fragaria × ananassa Duch.) is, among small fruits, the most cultivated and commercialized in Portugal. Recent studies have evidenced the positive effect of plant growth-promoting bacteria (PGPB) inoculation on strawberry production and, at the same time, provided an alternative strategy to reduce the use of fertilizers. In this
study the effects of root inoculation with three PGPB strains (Pedobacter sp. CC1, Bacillus safensis B106 and Bacillus subtilis B167A) on the physiology, growth, fruit production and quality of strawberry cv. Camarosa are presented.
RESULTS: PGPB inoculation significantly accelerated crop maturation, with inoculated plants fruiting about 2 weeks earlier than non-inoculated plants. Inoculated plants with Pedobacter sp. CC1 and Bacillus safensis B106 influenced the gas exchange parameters of strawberry plants. The contents of total phenolics and flavonoids in strawberry leaves were found to be greater with Pedobacter sp. CC1, when compared with non-inoculated plants. Furthermore, plants inoculated with the same bacterial strain showed enhancement in the dimensions of fruits, especially fruit length, and shape as well as in the total soluble solids content (°Brix).
CONCLUSIONS: The results showed that the PGPB Pedobacter sp. CC1 improved performance of strawberry plants, suggesting that it could be a potential biofertilizer for strawberry plant nutrition. © 2019 Society of Chemical Industry.
