4－硝基喹啉－1－氧化物（4NQO）对大麦损伤效应的研究

Studies on Damage Effect of 4NQO to Barley

４ＮＱＯ对大麦Ｍ１的出苗率、苗高、根长、根数、Ｍ１根尖细胞的染色体畸变率较之对照都有较明显的影响。试验结果表明，４ＮＱＯ对大麦具有明显的损伤效应。

The experiment results shwed that seedling ratio,seedling height,root length, root number of barley M1 and chromosomal aberration frequency of root tip cell of barley M1 is obviously influenced than check.
