Embodiment 1

[0024] a. Material selection: Select young stems of Aglaonema rotundum as explants during the growing season.

[0025] b. Disinfection of explants and induction of adventitious buds: Rinse the young stems of R. rotundum under tap water, soak them for 30 seconds in 70% alcohol by volume fraction, and then use mass volume percentage concentration Disinfect with 0.1% mercuric chloride solution for 8 minutes, rinse with sterile water 4 times, cut into segments about 1 cm long, inoculate them on the induction medium, take out the segments after 5 days and use 0.1% mercuric chloride in mass percent concentration again The solution was sterilized for 8 minutes, rinsed with sterile water for 5 times, and then transferred to a new induction medium. The success rate of disinfection was 71%, and adventitious buds could be formed on the explants in 60 days. Contains 2.0mg of 6-benzylpurine, 0.2mg of naphthaleneacetic acid, 20g of sucrose, 6g of agar, and the rest are MS;

Abstract

The invention discloses a tissue culture reproduction method of Chinese evergreen and aims to provide a tissue culture reproduction method of the Chinese evergreen with high reproduction speed, mass test seedling obtainment in a short term, little damage to a mother plant and the maintenance of mother plant fine traits. The method comprises the following steps: selecting young stems of eugenic Chinese evergreen as explants, disinfecting the explants, carrying out the adventitious-bud induction of an induction culture medium and coupling adventitious buds into a reproduction culture medium forsuccessive transfer reproduction; cutting and inoculating the buds to a rooting culture medium for rooting culture while the buds grow to the height of 3cm to 5cm; training the seedlings under natural light for 7 days to 10 days when the test seedlings grow to the height of 6cm to 7cm; and taking the test seedlings out, washing the rooting culture medium, planting in a volumetric mixture medium comprising sand, perlite, peat soil, and the like and obtaining planting seedlings after conventional culture. The invention can provide markets with mass Chinese evergreen test seedlings.

Description

Technical field: [0001] The invention relates to a method for tissue culture and propagation of Grass officinalis. Background technique: [0002] Aglaonema is a general name for plants of the genus Aglaonema in the family Araceae. It is a perennial evergreen herb native to India, Thailand, Vietnam, the Philippines, Malaysia and Indonesia in Southeast Asia. The plant height of rough rib grass is 20-150 cm. Leaves alternate, lanceolate to narrowly ovate, 10-45 cm long and 4-16 cm wide. The flowers are small and inconspicuous, the inflorescences are spathes, spathes are white or greenish white, and the fruits are berries, which turn red when ripe. Grass has high ornamental value and is an excellent foliage flower, which can be used as a high-grade foliage plant for indoor and garden viewing. [0003] There are three kinds of propagation methods for R. scutellaria, cutting and seed propagation. The speed of branch propagation is slow, and although seed propagation is an effec...
