A method for inducing flowering hybrid breeding with bamboo stalk buds for fiber

Abstract

The invention discloses a method for inducing flowering and crossbreeding of bamboo stalks and buds for fibers, which comprises the following steps: selecting any two kinds of fiber bamboos with a cellulose content of 40% to 60% and a lignin content of 15% to 25%. Parents: select the combination of flowering inducers as 100 μg / ml gibberellin solution, 200 μg / ml abscisic acid + 50 μg / ml methyl jasmonate mixed solution, 0.1% amylase + 0.05% glutathione mixed solution; use a stainless steel continuous syringe 100-200ml gibberellin solution, 100-200ml abscisic acid + methyl jasmonate mixed solution, 100-200ml amylase + glutinous Glutathione mixed solution, after each injection, use adhesive tape to seal the injection port; 60 to 90 days later, the buds outside the internodes of the bamboo stalks induced by the two parents are induced to flower, and the hybrid seeds are obtained through artificial pollination. Breeding and screening to obtain new germplasm or new varieties of bamboo for fiber with excellent characters.

Description

technical field [0001] The invention relates to a method for inducing flowering hybrid breeding and belongs to the technical field of plant breeding. Background technique [0002] The pulp and paper industry is one of the important pillar industries of China and even the world economy. With the rapid development of my country's economy, the demand for paper will continue to increase rapidly. Due to the relative shortage of forest resources in our country and the continuous improvement of laws and policies related to forest protection series, as well as the relatively low recycling rate of waste paper in the paper industry chain, the gap in timber resources can only be made up by imports to a large extent, and the country must not Import lumber and wood pulp without spending huge sums of money. However, as a plant natural resource widely distributed in my country, bamboo has the characteristics of wide distribution, strong adaptability, fast growth, early maturity, and high ...

Problems solved by technology

However, the overall level of bamboo genetics and breeding is still at a low level. It is urgent to formulate and implement strategies and goals for bamboo genetic improvement based on the current research status of bamboo genetics and breeding at home and abroad, so as to promote the development and utilization of bamboo resources for fiber.
