Breeding technology of konjak testtube taro

Abstract

A test tube technique for reproducing the konjak features that the paclobutrazol is added to the culture medium MS+NAA5-1 mg / L used for rooting the tissue culture seedlings of konjak, they are cultured at temp higher than 20 deg.C, under light radiation (1000 LX) for 20-25 days to form small bulb, when the weight of small bulb reeches 2-4 g they are cultured at lower than 15 deg.C in dark environment, after cultured in flask for 10-15 day they are sprouted and then transplanted in seedbed, and they are cultured at higher than 20 deg.C, while the fertilizer is proportionally and periodically applied.

Description

Technical field: [0001] The invention relates to a technique for multiplying konjac test-tube taro, which belongs to the field of agricultural biotechnology. Background technique: [0002] Konjac is the only plant that can synthesize a large amount of glucomannan. Glucomannan has a wide range of functions in industry, agriculture, medicine, and health food. It has attracted more and more people's interest and attention, and the planting area has continued to expand. However, the high disease rate of taro species and the serious degradation of excellent varieties restrict the development of this industry. Propagation of virus-free high-quality seedlings and taros through biotechnology has been successful in various plants such as potatoes and lilies, and has been widely used in production, achieving good social and economic benefits. At present, konjac has been able to breed excellent seedlings through biotechnology and transplant them to seedbeds for breeding, which provide...
