Abstract

In the study, it was aimed to determine whether the essential oil components (geraniol, carvacrol, citronellol and thymol) and their different concentrations (0, 2, 5, 10 and 20 ml/petri) would cause any allelopathic effects on the germination of wheat seeds. The experiment was carried out in the laboratory environment according to the divided plots experimental design in random plots. The effects of allelochemical species (Carvacrol, Thymol, Geraniol, Citronellol) and their doses were found to be statistically significant (p<0.01) on the germination rate and seedling dry weight of wheat seeds. The effects of allelochemical species (p<0.05) and doses (p<0.01) on seedling fresh weight were found to be statistically significant. As a result, it was determined that some of the herbal allelochemicals used were effective on seed germination and seedling growth in wheat, and the effect ratio increased as the dose increased. It is thought that some essential oil components can be used in the production of bio-herbicides for winter grass weeds, provided that similar studies are carried out on winter crop plants.

几种精油成分对小麦萌发和幼苗生长的化感作用

本研究旨在确定香叶醇、香芹醇、香茅醇和百里香酚的不同浓度(0、2、5、10和20 ml/petri)对小麦种子萌发是否有化感作用。实验在实验室环境下按照随机分块试验设计进行。化感化学物质(香芹酚、百里香酚、香叶醇、香茅醇)及其剂量对小麦种子发芽率和幼苗干重的影响均有统计学意义(p<0.01)。化感物质种类(p<0.05)和剂量(p<0.01)对幼苗鲜重的影响均有统计学意义。结果表明，所使用的部分草本化感剂对小麦种子萌发和幼苗生长有一定的影响，且效果比随剂量的增加而增大。如果对冬季作物植物进行类似的研究，认为一些精油成分可以用于生产冬季杂草生物除草剂。
