This invention belongs to the field of seed
germination technology for traditional Chinese medicinal materials, specifically providing a soaking solution containing walnut components, a seed dressing
powder composition, and its application in the
germination of *
Gynostemma pentaphyllum* seeds. The soaking solution is prepared by
water extraction from a mixture of dried walnut leaves, neem leaves, and
moringa leaves. The seed dressing
powder composition is a mixture of at least two of the following: walnut inner pericarp
powder, walnut green
husk powder, neem fruit powder, soapberry fruit powder, and sand. The
germination method includes steps such as soaking seeds in the soaking solution,
refrigeration, soaking in a bacterial suspension, dressing seeds with the seed dressing powder, germination, and
sowing. This invention does not use
plant hormones throughout the process, uses agricultural and
forestry by-products as germination materials, is low-cost, safe and
environmentally friendly, and simple to operate. The germination rate of *
Gynostemma pentaphyllum* seeds reaches over 61%, providing effective
technical support for the artificial cultivation of *
Gynostemma pentaphyllum*.
