Abstract
This research was accomplished within period from 2016 June to 2017 November at three locations in Tartous governorate viz. Al Thaora, Al Qumseia and Al Sorani. The seed germination of Jatropha curcas L. was studied by planting the seeds at Al Thaora and Al Sorani locations in three months of the year 2016 (June, July and August), and the growth of seedling was evaluated at Al Thaora, Al Qumseia and Al Sorani locations. The percentage of germination at Al Thaora was 97, 90 and 95 % which was better than at Al Sorani (70, 77.5 and 62.6) % in June, July and August respectively. The speed of germination was (8.82, 8.06 and 7.11) day/seed at Al Thaora and (11.11, 9.13 and 7.64) day/ seed at Al Sorani in June, July and August respectively. Germination was relatively homogenous in both locations. There were no differences in plant height between locations, and the diameter of stem at Al Thaora was better than Al Sorani, also the length and height of crown at Al Thaora was the best of the other locations.
Key words: Jatropha Curcas, Seed germination, Seedling growth.
