This invention discloses a cultivation method to improve the propagation efficiency of Rhodiola rosea, relating to the fields of plant cultivation and seed propagation technology. The cultivation method includes: (1) Seedling stage: after being treated with hormones, the seeds are sown in a light substrate and cultivated for 6-12 months to obtain strong seedlings; (2) Hydroponic transplanting and flowering induction stage: the strong seedlings are transplanted to a hydroponic system, and photoperiodic induction is performed using an artificial light source with a red-blue spectrum ratio of 1:1, combined with the phased adjustment of nutrient solution and the spraying of exogenous hormones to synergistically induce reproductive growth; (3) Pollination and seed collection stage: the seeds are collected after assisted pollination. This invention shortens the seed-to-seed cycle of Rhodiola rosea from the traditional 6 years or more to 2-3 years through multi-factor synergistic regulation, significantly improving the flowering rate and seed yield per plant, increasing the propagation efficiency by more than 99%, and is applicable to different ecotype seed sources, with the advantages of strong operability and good universality.

This invention proposes a process for propagating spiny cartilage seaweed (E. denticulatum) using callus tissue culture based on a callus-embryo-synthesis-complete seedling regeneration process, allowing for the creation of disease-free, uniform, and high-growth-potential seed sources. The process includes the following steps: acclimatization of broodstock using seawater filtration combined with AgNPs; sterilization and sample preparation; callus induction on solid PES medium; stimulation of somatic embryogenesis using a combination of plant growth regulators NAAA-BAP; and seedling regeneration on a suitable medium. This process increases the multiplication rate, shortens seedling production time, reduces genetic degeneration, and facilitates scaling up production in laboratory and seaweed breeding facilities in Vietnam.
