Embodiment 1

[0031] A simplified sugarcane test-tube plantlet rooting and seedling raising method is characterized in that it comprises the following steps:

[0032] (1) Prepare rooting medium: prepare rooting medium according to the following formula: 1 / 2MS macroelements + MS trace elements + MS iron salt + MS organic matter + naphthalene acetic acid 5-20 mg / L + sucrose 50 g / L;

[0033] (2) Sterilization of the rooting medium: the rooting medium was sterilized under high temperature and high pressure at 121° C. for 5 minutes;

[0034] (3) aseptic tube transfer: in the aseptic room or ultra-clean workbench, the sugarcane test-tube plantlet that has completed the multiplication culture cycle is transferred to the cooling rooting medium;

[0035] (4) rooting cultivation: the sugarcane test-tube plantlet in the rooting medium is moved into the cultivation chamber, and the control cultivation chamber environment is 25° C. of temperature, 80% of humidity, and 1200 lux of light intensity, and cu...

Abstract

The invention relates to a simplified sugarcane test-tube plantlet rooting and seedling raising method. The method is to transfer the sugarcane test-tube plantlet that has completed the multiplication and cultivation cycle to the rooting medium, cultivate it in a culture room for 24 to 96 hours, and then remove the rootless test-tube plantlet. After division and disinfection, plant them in planting pots with cultivation medium after 3 to 6 minutes. When the test-tube seedlings grow new leaves, the nursery management method is the same as the traditional nursery management method. The seedling method of the present invention replaces traditional rooted test-tube plantlets with rootless test-tube plantlets for transplantation, replaces traditional heterotrophic rooting with autotrophic+heterotrophic rooting, and the rooting culture time of sugarcane test-tube plantlets is shortened from 15 days to 1 to 4 days. The production efficiency is greatly improved, the production cost is reduced, and it is beneficial to the large-scale production and popularization of sugarcane healthy test tube seedlings.

Description

technical field [0001] The invention relates to a heterotrophic+photosynthetic autotrophic rooting method for plant test-tube seedlings, in particular to a simplified method for rooting and raising seedlings of sugarcane test-tube seedlings. Background technique [0002] Plant tissue culture generally goes through four stages, that is, primary culture (or establishment of a sterile culture system), subculture proliferation culture, rooting culture and seedling hardening and transplanting. At present, the sugarcane test-tube seedling rapid breeding technology that has been applied on a large scale in production also includes the above four stages. However, this traditional sugarcane test-tube plantlet production process is complex and requires high environmental conditions for cultivation, resulting in high cost of sugarcane tissue culture industrial production of test-tube plantlets, which has been unacceptable by the market and has limited the cultivation and production of ...
