Abstract

The present invention relates to a kind of tissue culture method of ornamental aquatic plant Antarctica, comprising the following steps: (1) pretreatment; (2) cutting the pretreated explant into 1-1.5cm long explant, each cut Each explant has at least one axillary bud; the explant after cutting is inserted into the first-generation culture medium and carried out the first-generation culture; (3) separate the first-generation adventitious buds in the first-generation medium, so that the length of the first-generation adventitious buds is controlled within 2cm; The first-generation adventitious buds after that are transferred to the propagation medium for cultivation; (4) the plants with a length greater than 3-4cm in the propagation medium are transferred to the rooting medium for cultivation; Take it out from the base, rinse it with clean water and transplant it into an ecological tank. This method can obtain a large number of new plants without being affected by seasons, temperatures, and regions, and quickly establish an aseptic propagation system for Aratarctica. Seedlings.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture, in particular to a method for tissue culture of ornamental aquatic plant Antarctica. Background technique [0002] Antarctica is a commonly used ornamental aquatic plant. Antarctica is a submerged herb, plantaceae, dicotyledons, emergent aquatic plants. In the wild, every flowering period, the water surface is as beautiful as a sea of ​​flowers, and you can also see it blooming in a plant tank. This kind of aquatic plants can adapt to a wide range of water quality changes in the water, and can also grow under low light, but it is still better to cultivate under stronger light. Antarctica is more like a green feather in shape, the difference is that the former has needle-like leaves and the latter has pinnate leaves. The current propagation method of Antarctica fir is cutting and lateral bud propagation. [0003] However, there is still a lack of mature technology for large-scale ...
