Seed selection method of honeysuckle flower Lonicera japonica Thunb III late-flowering variety

Abstract

The invention relates to seed selection method of a honeysuckle flower Lonicera japonica Thunb III late-flowering variety and is suitable for seed selection of a novel honeysuckle flower variety. The seed selection method comprises that triennial-quadrennial honeysuckle flowers cut and cultivated in honeysuckle flower production fields in the Pingyi county of the Shandong province are collected and transplanted; and through biological-character observation, related indicator determination, optimization, expanding propagation and cultivar comparison of the late-flowering variety, the honeysuckle flower Lonicera japonica Thunb III late-flowering variety which can flower four times in a year and has the first-flowering date of May 25th-30th and the end-flowering date of October 20th-30th is obtained. The honeysuckle flower Lonicera japonica Thunb III late-flowering variety has stable biological characters, strong stress resistance, high annual flowering frequency, a medicinal material yield improved by 12.8% than a medicinal material yield of the common germplasm hybrid honeysuckle flower variety, and improved chlorogenic acid and galuteolin content, and satisfies standard requirements of the pharmacopoeia of the people's republic of china (published in 2010). The honeysuckle flower Lonicera japonica Thunb III late-flowering variety has the flowering date delayed for about 10 days and thus the defect of harvest labor stringency in the flowering stage is overcome, and has an important meaning for guaranteeing a yield and quality of honeysuckle flower medicinal materials and improving economic benefits.

Description

technical field [0001] The invention relates to a technique for breeding medicinal plant varieties, which is specially used for breeding a new variety of honeysuckle "Lonicera No. 3" with stable properties and suitable for production needs. Background technique [0002] Honeysuckle has a long history of medicinal use and is a well-known traditional Chinese medicine.

[0003] In order to meet market demand, honeysuckle is planted in large areas in Shandong, Henan, Hebei, Shaanxi and o...

AI Technical Summary

Problems solved by technology

Honeysuckle has strong adaptability and relatively simple planting techniques, but picking flowers requires a lot of labor, which is an important link that limits production development and increases production costs

Especially in the main production area of ​​Pingyi County, Shandong Province, honeysuckle is planted in mountainous and hilly areas, and the flowering period of the plants is relatively concentrated and short. If there are insufficient flower pickers, the flower buds will open soon. economic benefits

Therefore, it is an important way to improve the quality, yield and economic benefits of honeysuckle to take effective measures, select and breed fine varieties, adjust the flowering period of honeysuckle plants, and make it relatively prolong the flowering period. However, no one has carried out corresponding research work so far.
