The effect of ghabich leaves extract on germination and seedlings growth of tomato

The aim of this study was to determine the effect of different concentrations of Ghabich (Guiera senegalensis J.F. Gmel) leaves extract on germination and seedling growth in tomato under laboratory conditions (in petri dishes). The concentrations used were 2.5,5,7.5 and 10%, each treatment with four replications. The study was carried out in two different experiments. In experiment one there was no significant differences in the germination rate and average length of the plumule between the different concentrations and control group. The best concentration 2.5% caused growth in the length of the radicle of 36.8 mm which was significantly different from the rest of the concentrations and the control (27.8 mm). In Experiment 2, the treatments 10% and 7.5% of the Ghabich extract had the lowest germination rate with significant differences compared with 5%, 2.5% and the control. The lowest mean length was for the 7.5% concentration (20.3mm) which was significantly lower compared with the other concentrations and control. There was no significant difference in the average length of the Radicle between the different concentrations and the control group.
