The Effect of some plant extracts and fungi exudate in time period of germination and killing of Convolvulus arvensis L.

Abstract

Different frequency of germination and killing of                                     Convolvulus arvensis  L. seeds differed in the 50 and 100  mg/ml concentrations of the plant extracts Where the first germination of the control treatment started on the fourth day, while the first germination of the treatment Melilotus indicus was recorded on the sixth day,  As for the concentration of 50  mg/ml, the first case of killing was recorded on the eleventh day for Euphorbia peplus Achieve Eruca vesicaria outperformed all treatments in the killing process in all days of the study As for the concentration of 100  mg/ml, the first germination of C. arvensis seeds was recorded on the seventh day in the treatment of Sonchus oleraceus While the first case of killing was recorded on the fourteenth day for the extracts Euphorbia peplus and Silybum marianum, Different frequency of the effect of fungal extracts on germination of C. arvensis seeds differed at 50  mg/ml concentration. The first  of germination was recorded on the fifth day in the treatment of the exudate  Penicillium resticulosum While the first case of killing was recorded on the tenth day of  A. alternate While  the concentration of 100 mg/ml, the first case of germination was recorded on the sixth day of the fungal exudate Penicillium resticulosum And record the  first case of seed killing was also recorded on the eleventh day of exudate Alternaria alternate.
