Abstract
[Objective] The aim was to study the effect of herbicide on the growth of early seedlings of rye(Secale cereale).[Method] Effect of two kinds of herbicide(Atrazine and APM) on seedling growth of rye was investigated at the physiological,biochemical and cellular level.[Result] The Atrazin significantly decreased the contents of chlorophyll a,b and soluble proteins.Rye seeds were treated with 0.100 and 1.000 mg/L Atrazine for 16 h,the contents of chlorophyll a and b decreased from 1.26(a),0.49(b) mg/g FW(control) to 1.15(a),0.46(b) mg/g FW(0.100 mg/L) and 0.81(a),0.33(b) mg/g FW(1.000 mg/L).The content of soluble protein decreased with the increasing concentration of Atrazin.Atrazin had no significant influence on the cell division and chromosome structure variation.The contents of chlorophyll a,b and soluble proteins had no significantly change under the treatment of APM,but the number of chromosome structure variation such as chromosome bridge,multipolar division cells,lagging chromosome and unequal division cells increased significantly.[Conclusion] The critical concentration of Atrazine was 0.100-1.000 and 4.000 mg/L of APM in rye.
