一种万寿菊一步成苗组织培养方法
By culturing marigold stem segments with buds in induction, proliferation, and seedling strengthening media and then directly inserting them into the cultivation substrate to simultaneously complete rooting, the problems of high cost, long cycle, and low survival rate in the rooting stage of existing technologies are solved. This achieves efficient one-step seedling production, improving production efficiency and seedling rate.

AI Technical Summary
Existing marigold tissue culture technology requires the separate preparation of special culture medium for the rooting stage, which increases costs and operational complexity. The separate rooting and transplanting processes result in long cycles, low survival rates, and susceptibility to microbial contamination, leading to low production efficiency.
After marigold stem segments with buds are cultured in induction, proliferation and seedling strengthening media, they are directly inserted into the cultivation substrate to simultaneously complete rooting and environmental adaptation, simplifying the seedling production method into a one-step process and eliminating the need for preparing and transferring rooting media.
It significantly reduces costs, shortens the tissue culture cycle, improves rooting rate and transplant survival rate, increases production efficiency, and achieves a seedling survival rate of over 90%, meeting the needs of large-scale production.
