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 as konjac, so they are greatly disturbed by humans.

Embodiment Construction

[0052] 1. Introduction

[0053] In December 1996, 5 adult konjac potatoes produced in Yunnan were introduced from the Xishuangbanna Tropical Botanical Garden in Yunnan. The leaves were cut off and the rhizomes were left, and the roots were brought back. They were placed in a shade shed with a shading degree of 85%, and planted in pond mud: peat soil : In the matrix of coarse sand=6:3:1, keep the relative humidity of the air at 90%.

[0054] 2. Obtaining sterile explants

[0055] The aseptic seedlings of seeds can be obtained by aseptic sowing indoors and outdoors:

[0056] Seeds were collected for germination tests from 1997 to 2000. The berries were harvested and sown in August each year after the berries were ripe (according to the standard of drying up on the flower pavilion), and the germination rate was counted 60 days after sowing.

[0057] Indoor sowing method: Rinse the seeds with tap water immediately after harvesting from the mother plant, treat with 70% alcohol for ...

Description

technical field [0001] The invention relates to a method for cultivating plant varieties, in particular to a method for in vitro rapid propagation of konjac potatoes. Background technique [0002] Konjac potato (Tacca chantrieri Andre), also known as arrowroot potato, tiger beard, black butterfly, etc., is a perennial herbaceous plant of the arrowroot family, an important representative species of the arrowroot family in my country, and is mostly born in tropical rain forests. The inflorescence of konjac potato is large, and the flowers, involucre and inner bract are all purple-black, which is rare in flowers. Its inner bracts are strip-shaped and tens of centimeters long, quite unique and beautiful; konjac has a tall and straight plant type with leathery leaves, and its flowers, inflorescences, and plants all have high ornamental value. Rhizomes are often used to treat gastric ulcer, high blood pressure, hepatitis, external application of burns, scal...
