Field performance of wheat and canola treated with plant growth promoting bacteria

随着全球人口的持续增长，对提供高质量食品、纤维和能源的农业的需求也在增加。与此同时，消费者要求减少农业生产的环境足迹**，并转向更可持续、更环保的生产方法**，以满足日益增长的需求。植物生长促进菌（PGPB）可以帮助实现这些目标。KGS集团**是一家咨询工程公司，提供包括水资源管理在内的广泛服务。**最初分离这两种菌株是为了协助磷的增溶和植物吸收，以**减少这种必需的植物养分从粪便进入水资源的运动。随后的试验表明，这些菌株除了改善某些植物的磷营养外，还可能对植物产生促进生长的作用。目前的Engage提案的目的是量化和更好地理解这些额外的植物生长促进作用，重点关注小麦和油菜在有和没有磷肥的田间条件下的幼苗活力、种子产量和种子质量，这是加拿大西部农业最重要的两种作物。该研究将为重要作物品种在田间条件下的行为提供重要的新信息，并帮助KGS集团确定这些PGPB品系的适用性和潜在市场。

As the global human population continues to rise, the demand for agriculture to supply high quality food, fibre**and energy increases. At the same time, consumer pressure is mounting to reduce the environmental footprint**of agricultural production and move toward more sustainable and environmentally friendly production methods**to meet the increase in demand. Plant growth promoting bacteria (PGPB) can contribute to achieving these**goals. Previous research for KGS Group identified two proprietary strains of Pseudomonas spp. KGS Group**is a consulting engineering firm that provides a wide range of services including water resource management.**The two bacterial strains were initially isolated to assist with phosphorous solubilisation and plant uptake to**minimize movement of this essential plant nutrient from manure into water resources. Subsequent**experimentation indicated that these strains may also cause plant growth promoting effects other than improved**phosphorous nutrition on some plants. The purpose of the current Engage proposal is to quantify and better**understand these additional plant growth promoting effects, focussing on seedling vigour, seed yield and seed**quality, under field conditions with and without phosphorous fertilization in wheat and canola, two of the most**important crops to western Canadian agriculture. This research will provide vital new information on the**behaviour of these PGPBs in important crop species under field conditions and assist KGS Group in defining**the applicability and potential market for these PGPB strains.
