Description
Technical field
The present invention relates to microscopic tissue sections technical field, particularly relate to a kind of resin slicer method for making of kernel maturity seed.
Background technology
Cereal comprises the grasses such as paddy rice, wheat, corn, and their seed is the main source of grain, feed and the raw material of industry.In cereal, endosperm is the important component part of seed, and its main reserve substance is starch and albumen.Starch accumulates in amyloplaste, and storage protein accumulates in proteosome.In cereal seed, the content of starch, albumen and ratio determine the nutritive value of cereal, have material impact to the processing of cereal and utilization, therefore study starch in seed endosperm and albumen has great importance to the quality and yield improving seed.
Kernel maturity seed is used in a large number at food, feed and industrial circle, and at present the research of cereal seed morphosis is mainly concentrated on to the stage of development of seed, also report is rarely had to the research of mature seed, mainly due to: 1. along with seed growth and grouting enrich, content of starch raises gradually, seed is hardening gradually, and embedding medium is difficult to infiltration, causes cutting into slices easily broken; 2. traditional dicing method needs to make tank and extends piece and drag for sheet, and mature seed due to inside finer and close, section can severe curl, cannot launch in tank; 3. traditional dicing method cannot cut complete mature seed section, can only cut scrappy region, brings difficulty to the areal distribution of each composition in research seed.Therefore need badly and existing microsection manufacture method is improved and optimized, invent a kind of microsection manufacture method of kernel maturity seed.
Summary of the invention
In order to overcome the deficiency of above-mentioned existing microsection manufacture method, the invention provides a kind of resin slicer method for making of kernel maturity seed.
The technical solution adopted in the present invention is as follows:
(1) draw materials: choose the normal kernel maturity seed of particle shape, carefully peel off clever shell, take out complete caryopsis for subsequent use;
(2) fixing:
1. 4% paraformaldehyde-2.5% glutaraldehyde immobile liquid is prepared: 100mL 0.2mol/L phosphate buffer (p H 7.4)+80mL10% paraformaldehyde aqueous solution+20mL 25% glutaraldehyde water solution;
