Description

A kind of screening technique of almond perfume (or spice) Tea Germplasm
Technical field
The present invention relates to Tea planting technical field, specially a kind of screening technique of almond perfume (or spice) Tea Germplasm.
Background technique
" almond is fragrant " black tea is using black tea made of a kind of special tea tree Raw material processing, and made tea has almond milk Perfume (or spice), this kind of germ plasm resource is extremely rare, and can not be recognized from the biology morphology of tea tree, therefore this kind of Tea Germplasm It is extremely difficult to carry out breed breeding.
Current screening technique is to carry out black tea processing trial-production respectively after single plant acquires fresh leaf or single plant cutting propagation, still Both methods workload is very big, and breakneck acceleration is relatively slow.Using the method for single plant acquisition fresh leaf processing trial-production, due to single plant tea Dark brownish green negligible amounts are set, processing difficulties cannot keep the original characteristic of germ plasm resource, therefore cause the tea tree with certain characteristic Germ plasm resource can not screen, and every plant of tea tree individually processes labor intensive and the time is extremely more, low efficiency, and utilize asexual cuttage Nursery, it is breeding time needs 4 years or more, this large-scale to the method for carrying out processing trial-production after cuttage seeding cultivating and growing again Cutting propagation may finally screen the kind that can process " almond is fragrant ", but this method from thousands of parts of Tea Germplasm Have the shortcomings that time-consuming, at high cost, heavy workload.Therefore a kind of new technical solution is needed, apricot can be quickly filtered out Benevolence perfume (or spice) tea tree breed, convenient for quickly planting this Rare Kinds.

S2, sample grinding: weighing 50-70mg sample, be put into grinder and grind, after taking-up, ultrasonic extraction 20-40min;
S3, sample extraction: into S2, the chloroform of 100-300 μ L is added in sample, after mixing, water is added, is mixed, ultrasound Extract 10-30min;Methoxamine hydrochloride pyridine solution is added into the derivative bottle of glass, is vortexed after concussion 2min, is trained in concussion It supports and carries out oximation reaction in case, after taking out sample, be placed at room temperature for 30min;
S4, data analysis: collecting sample data carry out GC-MS metabonomic analysis.
As a preferred technical solution of the present invention: it is lobate to acquire a bud two for three parts of tea tree sample standard deviations in step sl State.
As a preferred technical solution of the present invention: the cold methanol of 360 μ L and the internal standard of 40 μ L being added in step s 2 Merging grinder is ground.
As a preferred technical solution of the present invention: temperature is in 30-40 DEG C in concussion and cultivate case in step s3, instead 90min between seasonable.
As a preferred technical solution of the present invention: in step s 4, GC-MS chromatographic condition: DB-5MS capillary column, Carrier gas is high-purity helium, and flow velocity 1.0mL/min, the temperature of injection port is 260 DEG C, 1 μ L of sample volume, split sampling, split ratio 6: 1, solvent delay 5min.
As a preferred technical solution of the present invention: in step s 4, GC-MS Mass Spectrometry Conditions: electron impact ion source, 230 DEG C of ion source temperature, 150 DEG C of level four bars temperature, electron energy 70eV, scanning mode is full scan mode (SCAN).
As a preferred technical solution of the present invention: the helium purity is not less than 99.999%.
As a preferred technical solution of the present invention: mass scan range: m/z 50-500.
Compared with prior art, the beneficial effects of the present invention are: technical solution through the invention, it can be found that having almond Benzaldehyde cyanohydrin rich content in its metabolin of fragrant Tea Germplasm, and benzaldehyde cyanohydrin content is less or even the tea tree breed of nothing then can not Almond perfume is generated, and technical solution can quickly the content to benzaldehyde cyanohydrin in tealeaves metabolin carry out quickly through the invention Analysis, so as to quickly realize the screening operation of almond perfume (or spice) Tea Germplasm, by the original work for passing through the breeding of 4 years Greatly shorten, can accurately determine almond scented tea arborescence resource, more meet the needs of market, convenient to carry out, operation It is convenient, it is practical, convenient for promoting the use of.
Detailed description of the invention
Fig. 1 is 1 metabolin total ion current figure of " almond is fragrant " germplasm;
Fig. 2 is 2 metabolin total ion current figure of " almond is fragrant " germplasm;
