Abstract

Global demand for vegetable oil is projected to expand to 28 Mt by 2028. Oilseed rape (OSR) is the predominant oilseed crop in Europe. Its nutritional value is determined by seed oil content and fatty acids (FAs) composition. Insect pollination increases seed oil content, however, its benefit on FAs composition remains unknown. In this study, we address this gap by investigating the variation of OSR seed oil content and FAs composition along a gradient of bee abundance in farmed OSR fields. We used a pollinator exclusion experiment to disentangle the contribution of pollination processes, i.e. wind, self and insect pollination. We show that bees improved OSR nutritional value by increasing amount of poly-unsaturated FAs and decreasing the amount saturated and trans-saturated FAs. In addition, oil content was higher in seeds with than without access to pollinators. Our study provides for the first time, to the best of our knowledge, evidence that insect pollination enhances the quality value of OSR oil by affecting FAs composition. Such effect implies potential negative consequences with any further decline of pollinator abundance. More investigations are also needed to better understand the mechanisms by which insect pollination affects FAs composition, and the way to enhance such mechanisms.

蜜蜂提高油菜籽的油质
预计到 2028 年,全球植物油需求量将增至 2 800 万吨。油菜(OSR)是欧洲最主要的油料作物。其营养价值取决于种子含油量和脂肪酸(FAs)组成。昆虫授粉可提高种子含油量,但其对脂肪酸组成的益处仍不得而知。在本研究中,我们针对这一空白,调查了耕种的 OSR 田中蜜蜂丰度梯度上 OSR 种子含油量和脂肪酸组成的变化。我们使用了授粉者排斥实验来区分授粉过程(即风力、自花授粉和昆虫授粉)的贡献。我们发现,蜜蜂通过增加多不饱和脂肪酸的含量,减少饱和和反式饱和脂肪酸的含量,提高了 OSR 的营养价值。此外,有蜜蜂授粉的种子比没有蜜蜂授粉的种子含油量更高。据我们所知,我们的研究首次提供了证据,证明昆虫授粉会影响脂肪酸的组成,从而提高 OSR 油的质量价值。这种效应意味着传粉昆虫数量的进一步减少可能会带来负面影响。为了更好地了解昆虫授粉影响脂肪酸组成的机制以及加强这种机制的方法,还需要进行更多的调查。
