柠檬草油对大豆小白菜和甘蓝种子萌发的影响研究

EVALUATION OF THE PHYTOTOXICITY OF LEMONGRASS ESSENTIAL OIL ON THE SEEDS OF THREE CROPS

测定柠檬草油对大豆、小白菜和甘兰种子发芽力的影响表明,50ppm 以下的柠檬草油对大豆种子发芽无明显抑制作用,100ppm 以下对小白菜和甘蓝种子发芽无明显影响,但浓度超过500ppm 以上时,对3种作物种子的发芽均有强烈的抑制作用。因此,在利用柠檬草油防治种子贮藏霉变和虫蛀中,大豆不宜超过50ppm,小白菜和甘蓝不宜超过100ppm.对为防止食用大豆发芽、霉变和虫蛀,可使用500ppm 以上的柠檬草油。

The 10ppm,50ppm,100ppm,500ppm,1000ppm,or 5000ppm of lemongrass essential oil affecting the germination ability of the seeds of soybean,chinese cabbage and cabbage were evaluated.There were no obvious inhabitions on the germination of soybean seed by 50ppm or/less of lemongrass oil,that of Chinese cabbage and cabbage seeds by 100ppm or less of lemongress oil,but 500ppm or more of lemongrass oil evidently inhabited the germinations of all three crops The result indicated that in the contral of storage mildew, rot and pest of seeds by means of lemongrass essential oil,the dose wouldn't excess 50ppm for soypean that is used as grow,100ppm for Chinese cabbage and cabbage,but for soybean that is used as food or feed the 500ppm or more should be taken.
