Abstract : Percentage of seed germination of Cassia senna plants, growing in valleys of Makkah and the other growing in the mountains of Makkah was studied under laboratory conditions in petri dishes as well as under field conditions. Further, some soil chemical analysis was performed for the valleys and the rock soils. This study indicates that the seed germination in petri dishes start after 18 hours, and the percentage was fixed after 17 days in the seeds of valleys plant while it was fixed after 20 days in the other. However, the seed germination in soil started after 2 weeks of planting under field conditions, and the germination percentage was fixed after 4 weeks for the seeds of valleys plants while it was fixed after 6 weeks for the seeds of mountain plants, and there was no germination in the dark. The analytical results for the soil show that there was no significant differences in both valley and rock soils except the phosphorus content, which decreases in the rock soils.
