The effect of Radiate, herbicide and fungicide applications on yield and endogenous auxin and cytokinin levels in field-grown lentil seeds

在过去的25年里，加拿大已成为世界上最大的扁豆出口国之一，2008年约占50%。萨斯喀彻温省是加拿大主要的扁豆生产地。Loveland ProductsCanada Inc.为加拿大扁豆作物种植者提供植物生长激素、生长素和细胞分裂素的专利配方，称为辐射®。对小扁豆来说，辐射不仅是一种强大的根系刺激剂，而且还能增强植物产生更多这些必需的根系生长激素的能力。辐射提供了这些基本植物激素的独特平衡，持续支持最大的根生长和植物性能，包括小扁豆种子产量。辐射通常与除草剂或除草剂与杀菌剂联合施用于扁豆植物。除草剂和杀菌剂处理也可能导致扁豆植物生长素和细胞分裂素水平平衡的改变。因此，Loveland有兴趣评估辐射与除草剂和杀菌剂处理对扁豆种子天然生长素和细胞分裂素水平的潜在相互作用。这些知识可以帮助Loveland改进他们的辐射配方，以优化其对小扁豆种子产量的影响。评估和记录辐射对田间种植的小扁豆种子中自然产生的植物激素、生长素和细胞分裂素内源水平的影响也很重要。

Over the past 25 years, Canada has emerged as one of the world's largest exporters of lentils accounting forapproximately 50% in 2008. Saskatchewan is the primary lentil producer in Canada. Loveland ProductsCanada Inc. offers its patented formulation of the plant growth hormones, auxin and cytokinin, called Radiate®for Canadian lentil crop growers. Radiate is not only a powerful root stimulator for lentil plants but alsoenhances the plant's ability to produce more of these essential root growth hormones. Radiate provides theunique balance of these essential plant hormones which consistently supports maximum root growth and plantperformance, including lentil seed yield. Radiate is typically applied to lentil plants in combination with eithera herbicide or a herbicide in combination with a fungicide. Herbicide and fungicide treatments may alsocontribute to the shift of balance in auxin and cytokinin levels in lentil plants. Thus, Loveland is interested toevaluate the potential interactive effects of Radiate with herbicide and fungicide treatments on the natural auxinand cytokinin levels of lentil seeds. This knowledge may help Loveland improve their Radiate formulation tooptimize its effect on lentil seed yield. It is also important to evaluate and document the effects of Radiate onthe endogenous levels of the naturally occurring plant hormones, auxin and cytokinin, in field-grown lentilseeds.
