Problems solved by technology

The fruit of konjac potato is a berry, but whether the berry is shriveled or well-developed, it has been hung on the flower pavilion and needs to be propagated by external force, but its ability to rely on external force is not strong, thus affecting its propagation and reproduction; Berries, but the plants are somewhat toxic and difficult to disperse by insects. In addition, there is no significant wind-borne characteristics
In addition, the folks have the habit of using konjac potatoes for medicinal purposes, so they are greatly disturbed by humans.

Embodiment Construction

[0033] 1. Introduction

[0034] In December 1996, 5 konjac potato plants from Yunnan Xishuangbanna Tropical Botanical Garden were introduced from Yunnan Province. The leaves were cut to leave rhizomes and roots brought back. They were placed in a shade shelter with a shading degree of 85% and planted in pond mud: peat soil. : Coarse sand=6:3:1 in the matrix, keep the relative humidity of the air at 90%.

[0035] 2. Obtaining sterile explants

[0036] The aseptic seedlings of seeds can be obtained through indoor and outdoor aseptic sowing:

[0037] Seeds were collected from 1997 to 2000 for germination experiments. The berries were harvested and sown in August each year after they had matured (based on their dryness on the pavilion), and the germination rate was counted 60 days after sowing.

[0038] Indoor sowing method: immediately rinse the seeds from the mother plant with tap water, treat with 70% alcohol for 12s, rinse with sterile water for 5 times, then disinfect with 0.1% m...

Description

Technical field [0001] The invention relates to a method for cultivating plant varieties, in particular to a method for rapid propagation of konjac potato in vitro. Background technique [0002] Konjac potato (Tacca chantrieri Andre), also known as arrowroot, tiger whisker, black butterfly, etc., is a perennial herbaceous plant of the arrowroot family. It is an important representative species of the arrowroot family in my country. It is mostly found in tropical rain forests. The inflorescence of konjac potato is large, and the flowers, involucre and inner bracts are all purple and black, which are rare in flowers. The inner bracts are strip-shaped and tens of centimeters long, which are quite unique and beautiful. The konjac potato plants are tall and straight, with leathery leaves. No matter the flowers, inflorescences, and plants, they have high ornamental value. Rhizome is often used to treat gastric ulcer, hypertension, hepatitis, external application ...
