The aim of this study was to determine the effect of the hydrolates obtained as the by-products of the essential oil steam distillation process. The bioassays, which were undertaken in order to determine the effect on germination and initial growth of seedlings of some cultivated and weed species, were performed under controlled conditions with different concentrations of the hydrolates. Seeds of , , , , subsp. , , , and , and six weed species-, , , , , and -were treated with 10, 20, 50, and 100% hydrolate solution. The obtained results showed that the hydrolate had the least negative effect on the germination of cultivated species, such as soybean, sunflower and maize, whereas clover and alfalfa were the most sensitive. By comparison, all the tested weed species expressed high susceptibility. It can be concluded that the hydrolate has an herbicidal effect, in addition to its potential as a biopesticide in terms of integrated weed management.
本研究的目的是确定作为精油水蒸气蒸馏过程副产品获得的水解产物的效果。为了确定其对一些栽培物种和杂草物种种子萌发及幼苗初期生长的影响而进行的生物测定，是在不同浓度水解产物的控制条件下进行的。大豆、向日葵、玉米、白三叶、紫花苜蓿、黑麦草、早熟禾、狗尾草、稗草、反枝苋、藜和六种杂草（马唐、牛筋草、狗牙根、马齿苋、苘麻和龙葵）的种子用10%、20%、50%和100%的水解产物溶液处理。所得结果表明，该水解产物对大豆、向日葵和玉米等栽培物种的萌发负面影响最小，而三叶草和苜蓿最为敏感。相比之下，所有测试的杂草物种都表现出高度敏感性。可以得出结论，该水解产物除了在综合杂草管理方面具有作为生物农药的潜力外，还具有除草作用。
