The influence of herbicides on the growth and proline content of primary roots and on the ultrastructure of root caps
The root tip of a germinating seed is usually the first organ of a plant to contact possible herbicide residues in the soil. Therefore, we examined electron microscopically the responses of the root caps of very young seedlings of _Pisum sativum, Phaseolus vulgaris_ and _Vicia faba_ to low concentrations of three frequently used herbicides, chlorsulfuron, norflurazon and triallate. Additionally, herbicide-induced ... إقراء المزيد
