摘要
用０、５０、１００和１５０×１０－６浓度的苯酚溶液处理水稻幼苗，本实验的目的是探讨苯酚对水稻幼苗生长的影响。实验结果如下：苯酚抑制水稻幼苗生长，且随着浓度的增加，其抑制作用越明显。１５０ｐｐｍ是抑制作用最强的浓度。经苯酚处理后的水稻幼苗，其根和茎的生长都抑制了，而鲜重、干重、水分含量和叶绿素含量则明显减少，硝酸还原酶和过氧化物酶活性也下降了。
Rice seedlings were treated with phenol at the rate of 0,50,100 and 150×10 -6 .The aim of this study attempts to investigate the effect of phenol on the growth of rice seedlings.The main results are as follow:Phenol showed inhibition on the growth of rice seedlings,and the inhibition was increased with the increase of concentration,150 ppm is the optimal concentration.Phenol treatment resulted in a decrease of the length of root and stem.There was strong decrease in fresh weight,dry weight,water content and chlorophyll content of rice seedlings after phenol treatment.Application of phenol brought about the decrease of nitrate reductase activity and peroxidase activity in rice seedlings.
