Abstract

Abstract: Two orders of magnitude corms of bulbil-yellow konjac（Amorphophallus konjac K.Koch） were used as test materials. The method of artificial induction blooming and seeding of bulbil-yellow konjac were studied through technical means that spraying mixed solution of gradient auxin and gibberellin at different coentrations, light treatment, drying in natural shade, embedding medium after and before flower bud differentiation. The results showed that the 2.0 kilogram and above corm of abloom rate is higher than 1.0~1.5 kilogram corm, the highest abloom rate reach 93.33%. The 2.0 kilogram and above corm of seed setting rate reach 81.11%, that is the highest with condition of light treatment, hormone ratio is 1∶1 200, and embedding medium after flower bud differentiation. The 2.0 kilogram and above corm of seed amount is the most, there are 4 442 seeds, and the breeding multiple is nearly 300 times, that is in condition of drying in natural shade, hormone ratio is 1∶800, and embedding medium after flower bud differentiation. In conclusion, the method of the 2.0 kilogram and above corm, hormone ratio is 1∶400~1∶1 200, and embedding medium after flower bud differentiation, is worth popularizing and applying in production practice.

Key words: bulbil-yellow konjac（Amorphophallus konjac K.Koch）, blooming and seeding, artificial induction
