Abstract

To investigate the interaction of SCARIFICATION, stratification and gibberellic acid (GA3) treatments on the seeds of GOLDEN RAIN TREE, the following treatments were used: concentrated sulfuric acid for 0, 30, 45 and 60 min, stratification at 3-5°C for 0, 15, 30 and 60 d and GA3 with the concentrations of 0, 100, 200 and 300 mg rl. Results indicated that the highest GERMINATION percentage (67%) was obtained from 60 min acid SCARIFICATION with 60 d stratification. The interaction between seed coat removal and stratifying for 0, 5, 10, 15, 20, 25 and 30 d was also studied. Results indicated that the highest GERMINATION percentage (96.3%) was obtained from seed coat removal and keeping the seeds for 30 d at stratification temperature. Among all treatments, the highest GERMINATION rate (2.4) was obtained from seed coat removal and 25 d stratification. Similarly, the highest GERMINATION value was also obtained from the same treatment. Finally, it was concluded that GOLDEN RAIN TREE seeds had a double dormancy of both seed coat and embryo dormancies. Results of using treatments on CHINESE RAIN TREE seeds indicated that SCARIFICATION and stratification could only enhance gennination rate, and since just SCARIFICATION improved seed GERMINATION, it was concluded that the seeds of CHINESE RAIN TREE had only seed coat dormancy.
