초록

This study was investigated the effect of immature rhizome production according to harvest times-based treatment method for seed production of Gastrodia elata. The results revealed that when the tuber weight of G. elata harvested in spring (GEHS) was ≥ 100 g, the rate of artificial fertilization, protocorm formation, and immature rhizome formation was 90.9%–94.8%, 3.1%–5.4%, and 10.1%–15.3%, respectively. When G. elata harvested in fall (GEHF) was treated at a low temperature for 4 weeks or more, the rate of artificial fertilization, protocorm formation, and immature rhizome formation was 70.4%–87.6%, 2.2%–2.6%, 8.7%–9.5%, respectively. Therefore, to produce seeds and immature rhizomes, GEHS must have tubers of more than 100 g, whereas GEHF requires breaking dormancy by low-temperature treatment for 4 weeks or more. Compared with those of GEHS, the rate of artificial fertilization, protocorm formation, and immature rhizome formation was lower in GEHF; however, it was higher than those in the natural germination state. Thus, it can be expected that G. elata can be produced throughout the year by ensuring that the seeds and immature rhizomes of G. elata are produced using a constant tuber weight and by breaking dormancy with low temperature treatment.
