项目摘要
The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to provide a new class of biorational chemicals (based on chemical communicants from plant symbiotic fungi) that provide season-long improvements in plant productivity including enhanced root growth, resistance to a variety of stresses including drought, and increases in plant yield. This system will be developed for delivery as a seed treatment or as an augmented fertilizer. The novel products will be sold to famers through already-developed delivery systems primarily through agricultural distributors and seed companies. They are expected to increase plant root development, crop yields and tolerance/resistance to drought and other adverse conditions. The products can be used equally well by large and sophisticated farmers and seed companies, including those using advanced plant genetic traits, but is also adaptable to smaller growers since the input costs to users will be less than competitive technologies for especially coping with adverse environmental stresses. These tools and advances will assist is overcoming the adverse effects of climate change and provide technologies to maximize scarce water resources.This SBIR Phase I project proposes to formulate the active chemicals to provide user-friendly products for delivery in suitable agricultural systems including seed treatments and augmented fertilizers, and to evaluate prototype products on their advantages in the greenhouse, pilot scale and field trial systems. The field trials will be conducted under conditions of drought stress and will permit measurement of water use efficiency of conventional and advanced drought tolerant corn hybrids in the presence and absence of the new products, and will provide a means to determine the mechanism by which the active chemicals provide improvements in plant performance. This third goal is essential since the chemicals as applied are present only during seed germination, but enhance plant performance throughout the season. The formulations are based on novel systems that will sequester volatile active chemicals but release them only when seeds are germinating. The plant performance characteristics that will be measured include enhanced root development throughout the season, enhanced yield parameters under water limiting conditions, and measure water use efficiency.
这个小型企业创新研究(SBIR)项目的更广泛的影响/商业潜力是提供一种新型的生物化学物质(基于植物共生真菌的化学传递体),提供长达一季的植物生产力改进,包括增强根生长,抵抗包括干旱在内的各种压力,并增加植物产量。这一系统将被开发为种子处理或作为补充肥料来交付。这些新产品将通过已经开发的交付系统主要通过农业分销商和种子公司销售给农民。预计它们将增加植物的根发育、作物产量以及对干旱和其他不利条件的耐受性/抵抗力。这些产品同样可以被大型和成熟的农民和种子公司使用得很好,包括那些使用先进植物基因特征的农民,但也适用于较小的种植者,因为用户的投入成本将低于竞争对手的技术,特别是应对不利的环境压力。这些工具和进展将帮助IS克服气候变化的不利影响,并提供最大限度利用稀缺水资源的技术。SBIR第一阶段项目建议配制活性化学品,以便在适当的农业系统中提供用户友好型产品,包括种子处理和增肥,并评估原型产品在温室、中试规模和田间试验系统中的优势。田间试验将在干旱胁迫条件下进行,将允许在有和没有新产品的情况下测量常规和先进耐旱玉米杂交种的水分利用效率,并将提供一种手段来确定活性化学品改善植物表现的机制。第三个目标是必不可少的,因为所应用的化学物质只在种子萌发期间存在,但在整个季节都能提高植物的表现。这些配方基于新的系统,可以隔离挥发性活性化学物质,但只有在种子萌发时才会释放它们。将测量的植物性能特征包括促进整个季节的根系发育,提高限水条件下的产量参数,以及测量水分利用效率。
