不同辅助授粉方式对烟草种子产量和质量的影响

Effects of different supplementary pollination methods on seed yield quality of tobacco

以烤烟品种云烟87为试验材料,比较人工摇粉、可溶性淀粉介质花粉辅助授粉、蔗糖液体辅助授粉3种辅助授粉对烟草种子产量和质量的影响。结果表明,与自然授粉比较,辅助授粉的烟草种子产量、单果粒数增加明显,其中可溶性淀粉介质花粉辅助授粉、人工摇粉对提高烟草种子产量和单果粒数效果尤为明显,分别比对照提高了39.7%、87.4%和28.4%、82.5%,与对照差异显著;不同辅助授粉方式对烟草种子质量无明显影响。人工摇粉为一种经济高效的辅助授粉方式。

The flue-cured tobacco variety Yunyan 87 was used as the test material. The effects of artificial rocking, soluble starch medium pollen-assisted pollination, and sucrose liquid-assisted pollination on the yield and quality of tobacco seeds were compared. The results showed that compared with natural pollination, the yield of tobacco seeds and the number of single fruit grains were significantly increased. Among them, soluble starch media pollen-assisted pollination and artificial rocking are particularly effective in increasing tobacco seed yield and single fruit number, which are 39.7%, 87.4%, 28.4%, and 82.5% higher than the control, respectively, which are significantly different from the control. Different auxiliary pollination methods had no significant effect on tobacco seed quality. Artificial shaking is a cost-effective auxiliary pollination method.
