摘要:

采用平皿培养法考察蒈烷-3, 4-二醇在水溶液中对一年生黑麦草和油菜根、茎伸长的抑制作用, 探讨其作为水基除草剂的应用潜力。结果表明: 蒈烷-3, 4-二醇微溶于水, 可在少量亲水性有机溶剂和表面活性剂作用下配制成浓度大于20mmol/L水乳液, 能够抑制黑麦草和油菜根、茎的伸长, 表现与浓度相关的除草活性, 对黑麦草的根、茎伸长的半数抑制浓度(IC50)分别达到1.12和1.73mmol/L, 而对油菜根、茎伸长的IC50分别达到1.23和2.12mmol/L。其除草活性明显高于天然单萜二醇对孟烷-3, 8-二醇, 而稍低于商业除草剂草甘膦, 有望进一步研究开发作为水基植物源除草剂。

Abstract:

The inhibition effect of carane-3, 4-diol in aqueous solution against the root and shoot growth of annual ryegrass(Lolium multiflorum Lam.) and rape(Brassica campestris) was investigated using a Petri dish culture method for the potential as water-based herbicides. The results of solubility test showed that carane-3, 4-diol was slightly soluble in water, while it could be made into water-based emulsion with a concentration more than 20 mmol/L by employing a small amount of hydrophilic organic solvents and surfactants. The results of herbicidal activity experiment showed that carane-3, 4-diol could inhibit the root and shoot growth of annual ryegrass and rape, which showed the concentration-dependent herbicidal activity. The half-maximal inhibition concentration values in aqueous solution against the root and shoot growth of annual ryegrass were 1.12 and 1.73 mmol/L, and the values that against the root and shoot growth of rape were 1.23 and 2.12 mmol/L, respectively. Additionally, carane-3, 4-diol showed higher herbicidal activity than that of natural monoterpenic diol p-menthane-3, 8-diol, as well as the slightly lower herbicidal activity than that of commercial herbicide glyphosate. It was expected to be further developed as a water-based botanical herbicide.

Key words: monoterpenic diol, carane-3, 4-diol, herbicidal activity, water-based herbicide
