The effects of different methanol extracts of
Convolvulus arvensis on phytohormones (indole acetic acid (IAA), gibberellic
acid (GA), abscisic acid (ABA) and salicylic acid (SA)) levels of corn were
investigated.
It was observed that all concentrations of
methanol extracts (50 µl, 75 µl, 100 µl) of roots, stems and leaves of C. arvensis
decreased the mitotic index and also caused abnormalities in chromosomes.
On the other hand, phytohormone levels have
been changed by application of different extracts at various concentrations.
Compared with the control, GA levels decreased significantly whereas ABA levels
increased in all the application groups.
