Culture technology for tissues of baeckea frutescens

Abstract

The invention discloses a culture technology for tissues of baeckea frutescens. The baeckea frutescens is also named as broom twigs, chicken-shaped pine, saokamu, abies holophylla and litsea viridis.The baeckea frutescens belongs to short and small shrubs, is rare dungarunga, and is 1-2m in height; the baeckea frutescens includes more bald branches; the baeckea frutescens is simple-leaf, the leaves are opposite, and are upright or expanded; leaves are linear and conical, tips are sharp, grooves are formed on the leaves, bulges are formed under the leaves, and the leaves contain transparent glandular opaque spots; flowers are small and white, singly grow at the axils, each base has 2 bracteoles and a short handle; the porocalyx is bell-shaped, includes 5 cracks, and is membranous and persistent; and 5 petals are round, the ovary has 3 locules and each locule contains a plurality of ovules. Capsules are about 1mm in length and are cracked at the upper parts. The seeds are cornered. Thebaeckea frutescens flower in July and August. The whole herb or root of the baeckea frutescens can be used into medicines, can be picked in the whole year and can be dried for use or freshly used. Theculture technology disclosed by the invention adopts stem sections with buds of the baeckea frutescens as explants, realizes in-vitro regeneration of the baeckea frutescens by the processes of bud induction, bud proliferation culture, rooting culture, seedling hardening and transplantation and the like, and provides technical guarantee for massive breeding, rapid propagation and new-variety promotion of the baeckea frutescens.

Description

Problems solved by technology

In the past, Pinus pine seedlings were mainly propagated by seed sowing. Due to the low germination rate of the seeds, it was far from meeting the needs of large-scale production of Pinus pine seedlings.

Moreover, the differences in medicinal components between the offspring of seed propagation are unfavorable for the popularization of excellent varieties of Pinus pine
