Rapid rooting and seedling-forming method for psammosilene tunicoides by water culture

Abstract

The invention discloses a rapid rooting and seedling-forming method for psammosilene tunicoides by water culture. The method comprises the following steps: selecting biennial psammosilene tunicoides,after all seeds of the psammosilene tunicoides are harvested in a seed harvesting period, taking green stem sections with leaves and a length of 5-8 cm from the psammosilene tunicoides, reserving three pairs of bud points and three pairs of leaves in each stem section, carrying out disinfection treatment with carbendazim, and carrying out culturing in a water-culture rooting culture solution underthe condition of an artificial climate box, wherein the water-culture rooting culture solution is an IBA solution with a concentration of 0.5-1 ppm, and the culture conditions set by the artificial climate box are as follows: (1) a temperature of 22 DEG C, a humidity of 60%, an illumination intensity of 15,000 lx and the culture time of 16 hours; and (2), a temperature of 16 DEG C, a humidity of60%, an illumination intensity of 0 lx and the culture time of 8 hours. The method provided by the invention has the advantages of rapid rooting, large root system amount, strong root system, high seedling forming rate and low cost, solves the problems of poor seedling emergence potential, long seedling emergence period, low seedling forming rate and the like for seedling raising of psammosilene tunicoides seeds, and provides a technical support for industrial rapid propagation of the psammosilene tunicoides in the future.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant breeding, and in particular relates to a method for rapid rooting and seedling formation of Jin Tiesuo in hydroponics. Background technique [0002] Psammosilene tunicoides (Psammosilene tunicoides) is a single-species perennial herb of Caryophyllaceae. Jintiesuo has important medicinal value. Its dried roots are used as medicine in the folks. It has the functions of dispelling blood stasis, relieving pain, dispelling rheumatism, and reducing inflammation. , Jingulian Capsules, Baibaodan, Tongxuekang Capsules and other raw materials of Chinese patent medicines. The distribution area of ​​wild resources of Jintiesuo is narrow and the quantity is small, coupled with a large number of human excavation, the distribution of wild resources has decreased sharply, and it has been listed as a national second-class protected plant. In order to meet the demand of Jintiesuo medicinal materials marke...

AI Technical Summary

Problems solved by technology

However, the seed propagation of Jintiesuo mainly has the following problems: First, because the inflorescence of Jintiesuo is an infinite inflorescence, there are problems of different seed maturity periods, so that the maturity of each seed is inconsistent, and most people fail to do it during the harvesting of seeds. Harvested in stages, some of the seeds were shriveled, which reduced the quality and emergence rate of Jin Tiesuo seeds as a whole; second, the emergence of the seeds after sowing was poor, and the emergence period was as long as one month, and the emergence was irregular

The third is that Jintiesuo is a perennial plant, and the seeds are easy to fall off after maturity. Every year, seeds fall in the field to germinate naturally, resulting in an uncertain commodity life of Jintiesuo roots in the field.

There are also relatively many reports on the method of rooting and seedling growth through tissue culture of Jin Tiesuo, but there are also defects such as long cycle time and high cost.
