菲、萘对小麦种子的生态毒性效应
Eco-toxicology Effects of Phenanthrene and Naphthalene on Wheat Seed Germination
摘要
Abstract
A biological incubation experiment was conducted to testify the inhibition effect of phenanthrene and naphthalene on rates of seed germination,root and stem elongation and content of chlorophyll for wheat. Results indicated that phenanthrene and naphthalene single and combined treatments had an inhibition effect on seed germinating potentiality and germination rate,especially in higher mass concentration treatments. Statistical analyses showed that correlation coefficient between the mass concentration of phenanthrene and naphthalene and seed germinating potentiality was greater,r was 0. 95 and 0. 98,respectively. Phenanthrene and naphthalene single and combined treatments had an inhibition effect on root and stem elongation, especially in the higher mass concentration treatments,for example,root elongation decreased 89% and 86% in the phenanthrene and naphthalene 0. 2 g/L treatments,and decreased 87% in higher mass concentration combined treatment. The inhibition effects on root elongation were combined treatment> naphthalene treatment > phenanthrene treatment, combined treatment> phenanthrene treatment > naphthalene treatment for stem elongation; the contents of chlorophyll in combined treatments were more sensitive than single treatments, and the effects on chlorophyll a was basically in accordance with chlorophyll b.关键词
