摘要： 水培条件下,研究不同油酸水平对黄瓜幼苗生长的直接影响.与对照相比,生物量和生理指标等表明,油酸10 μL/L水平对黄瓜生长几乎没有负面影响,而油酸水平为100,500,1 000μL/L则表现出一定的抑制效应.其中,1 000 μL/L水平中黄瓜的生长明显受到抑制.试验还表明,油酸对黄瓜幼苗没有表现出直接的生长刺激效应.

Abstract: A water culturaLexperiment about the effect of oleic acid at different levels on the growth of cu-cumber ( Cucumber sativus L.)seedling was conducted in greenhouse.The results indicated that at the leveLof 10 μ L/L, the oleic acid had no effect on the growth of the cucumber seedling compared with the controL.At the leveL100, 500, 1 000 μ L/L, oleic acid had the negative effect on itsgrowth.The growth was strongly affect-ed by the oleic acid at the leveLof 1 000 μ L/L, and the difference was statistically significant compared to the controL.According to the data, the experiment showed that the oleic acid had no directly positive effect on the growth of cucumber seedling.

Key words: Cucumber, Oleic acids, Water cultural condition , Continuous cropping problem
