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，加拿大已经成为世界上最大的扁豆出口国之一，在2008年约占50%。萨斯喀彻温省是加拿大主要的小扁豆产地。Loveland ProductsCanada Inc.为加拿大扁豆种植者提供名为Radiate®的植物生长激素、生长素和细胞分裂素专利配方。辐射不仅对小扁豆植物是一种强大的根刺激剂，而且还可以增强植物产生更多这些必要的根生长激素的能力。Radiate提供这些必需的植物激素的独特平衡，持续支持最大的根生长和植物表现，包括小扁豆种子产量。Radiate通常与除草剂或除草剂与杀菌剂组合应用于小扁豆植物。除草剂和杀菌剂处理也可能有助于改变小扁豆中生长素和细胞分裂素水平的平衡。因此，Loveland有兴趣评估辐射与除草剂和杀菌剂处理对小扁豆种子自然生长素和细胞分裂素水平的潜在交互影响。这些知识可能有助于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。同样重要的是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的内源水平的影响。

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.
