Abstract

The invention relates to a screening method for the tea plant clone containing different catechuic acid contents and components, which solves the problems that the detection for the catechuic acid contents and the components in the callus or clone of tea plants needs long time and the operation is complex in the screening technology. The screening method includes four operating steps of inducing and successively transferring the clone, screening the callus containing different catechuic acid contents, screening the clone containing different catechuic acid contents, and screening the clone containing different catechuic acid components. The invention can screen the clone containing different catechuic acid contents and components and display the difference of the catechuic acid contents of the callus within the short time of 5-10 min, thereby having the great advantages that the catechuic acid detection can be performed during the successive transfer operation process; a plurality of samples can be analyzed once by the thin layer chromatography and identification of the catechuic acid components of the clone of the tea plant, in addition, a new component can be also found by the thin layer chromatography and identification, thereby the screening of the clone containing different catechuic acid contents and components is accelerated.

Description

technical field [0001] The invention relates to a screening method for plant cell lines, and a screening method for cell lines containing different catechin contents and components in tea trees. Background technique [0002] The synthesis of plant flavonoids is affected by external environmental factors. Factors such as light, temperature, and nutrition will all affect the synthesis of phenolic substances in tea trees. Since there are many limiting factors in studying the biosynthesis and metabolism of phenolic substances in intact tea plants, tea callus and cell suspension culture system have undoubtedly become a good platform for studying the secondary metabolism of tea plants. Screening tea cell lines with different catechin content and components is the prerequisite for the establishment of this good platform. [0003] There are many common screening methods for cell lines containing special substances, and finding an effective and easy special substance detection metho...
