The seeds of Chia-hu (B. falcatum L.) were harvested at weekly intervals from 55 to 76 days after flowering (DAF), They were dried and sealed in plastic bags with calcium chloride, and then stored (1) in a refrigertor at 0-5°C, (2) in a desiccator under room temperature, (3) in a incubator at 36°C, (4) on the bench of this laboratory under room temperature. Germination rate and Gt50 for each treatment were tested at 3, 6, 9 and 12 months after storage. The results were summarized as follows:
(1). The best germination rate and GT50 were obtained in the fresh seeds harvested at 69 days after flowering with a germination rate of 71% and GT50 of at 21 days.
(2). The germination rates and GT50 of dry seeds varied with time and mtehods of storage. The best storage method was found with incubator at 36°C, which resulted in a mean germination rate of 77% and GT50 of 14 days. The results stored in desiccator under room temperature and in refrigertor at 0-5°C were better than that stored on the bench in this laboratory, which lost their viability in 6 months, that meight due to the great fluctuation of ambient temperature and relative humidity.
(3). The maximum germination rate for the seeds stored in the refrigerator, desiccator and under room temperature were found in the periods of 6 months after storage. The seede stored in the incubator, however, had lost their vigour in 9 months after storage.
(4). Among the four harvesting date, the best germination rate and GT50 were observed in the seeds harvested 69 days after flowering.
