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

Ultrastructural responses of root caps to the herbicides chlorsulfuron and metsulfuron methyl
Herbicide residues may affect seedlings during early stages of their development. We studied this possibility by the use of light and electron microscopy after incubation of germinating seeds of_Pisum sativum_ L. and_Zea mays_ L. with different concentrations of chlorsulfuron and metsulfuron-methyl. By in vitro experiments, we have shown that both herbicides caused growth reduction of the very young roots, and ... إقراء المزيد
