Marine plant derivatives to enhance crop plants

在接下来的几十年里，我们必须提高农业生产率，以应对不断增长的人口和燃料供应，并提高农业的可持续性。生物投入是实现这一目标的一种方式。海藻已被开发为生物刺激剂的生产者，在加拿大，节伞已被开发成商业产品，销往世界各地。拟议的工作将使人们广泛了解一套海藻提取物和配方对加拿大东部主要作物的真菌病原体提供生物防治措施的能力。我们将评估精选的海藻提取物及其制剂的效果，以减少真菌病原体的生长，并促进植物生长。将在培养皿条件下和在特定海藻提取物和制剂存在的情况下收集关于真菌生长和发育方面的数据，以期确定那些最有效的海藻提取物和配方。此外，将评估具有最大抗真菌活性的材料(提取物和制剂的组合)对植物生长的促进作用和对作物生理的特定方面的影响。阿卡迪亚海洋植物已经对海藻提取物进行了初步研究，并将为拟议的工作提供最有趣的类型。这项研究中使用的评估作物将是番茄，因为它是加拿大东部广泛生产的一种高价值作物。这项工作将通过阿卡迪亚海洋植物和麦吉尔大学史密斯实验室研究小组之间的合作进行，以详细说明和实施他们迄今的过程和理解。海藻衍生材料的抗真菌和促进生长能力方面的工作将使人们更好地了解其当前产品的适用性，以及新产品和进一步产品的基础，使其成为快速扩张的生物制品领域的领导者。这也将增强加拿大农业的可持续性和经济性，使加拿大在生物制品的农业应用方面进一步领先。

Over the next few decades we must increase both agricultural productivity, to deal with growing populations and fuel supply, and agricultural sustainability. Biological inputs are one way to achieve this. Seaweeds have been exploited as producers of biostimulants, and within Canada, Ascophyllum nodosum has been developed into commercial products sold around the world. The proposed work will lead to a broad understanding of the ability of a set of seaweed extracts and formulations to provide biocontrol measures against fungal pathogens of key crop plants of eastern Canada. We will evaluate the effects of selected seaweed extracts and formulations of these for ability to diminish the growth of fungal pathogens, and also for the enhancement of plant growth promotion. Data will be collected on aspects of fungal growth and development under Petri plate conditions and in the presence of specific seaweed extracts and formulations, with a view to identifying those with greatest efficacy. In addition, the materials with greatest antifungal activity (combination of extract and formulation) will be evaluated for plant growth promotion and effects on specific aspects of crop physiology. Acadian Seaplants has conducted preliminary research regarding the seaweed extracts and will provide the most interesting types for the proposed work. The evaluation crop used in this research will be tomato, as it is a high value crop produced extensively in eastern Canada. The work will be conducted through a collaboration between Acadian Seaplants and the Smith laboratory research team at McGill University, in order to elaborate and implement their processes and understandings to date. The work regarding anti-fungal and growth stimulation capability of the seaweed-derived materials will provide a better understanding of the applicability of their current product, and with new products and the foundations for even further products, establishing it as a leader in the rapidly expanding biologicals sector. This will also enhance the sustainability and economics of Canadian agricultural, giving Canada further leadership in the agricultural application of biologicals.
