AI Technical Summary

Technical Problem

Existing methods for tissue culture of ginger truncate stem cells suffer from low tuber germination rates, slow propagation speeds, and poor rooting effects, making it difficult to meet the market demand for large-scale ginger truncate stem cells seedlings.

Method used

Strict disinfection procedures were employed, combined with optimized formulations of induction, proliferation, and rooting media. Furthermore, appropriate light and temperature control, along with the use of foliar fertilizers and fungicides, promoted the germination and growth of truncated ginger rhizomes.

Benefits of technology

It significantly improved the germination rate, proliferation coefficient, and rooting rate of truncated ginger tubers, and the cultivated seedlings were robust with a high transplant survival rate, providing technical support for the rapid propagation and large-scale cultivation of truncated ginger.

Abstract

The present application relates to the technical field of plant tissue culture, and provides a tissue culture method for promoting germination of Zingiber zerumbet Smith, wherein Zingiber zerumbet Smith tubers are used as explants, and after being subjected to disinfection treatment, the explants are inoculated into an induction medium, a proliferation medium and a rooting medium in sequence, and then are subjected to acclimatization, seedling raising and transplanting, so that finished Zingiber zerumbet Smith seedlings are obtained. The germination rate, the proliferation coefficient and the rooting rate of the Zingiber zerumbet Smith tubers can be significantly improved by using the culture media which are optimized and adjusted in the technical scheme of the present application. In addition, the reasonable application of foliar fertilizer and fungicide after transplantation in the present application can further improve the growth vigor and the disease resistance of Zingiber zerumbet Smith seedlings, and ensure the survival rate of the seedlings, thereby providing reliable technical support for rapid propagation and large-scale planting of Zingiber zerumbet Smith.
