Abstract

The invention discloses a paraffin section method for fern gametophytes, which comprises the steps of material selection and fixation, washing, coloration and bluing, dehydration and hyalinizing, waxing and embedding, sectioning, patching, dewaxing and mounting, as well as microscopic examination and photographing, wherein improved FAA (formalin, acetic acid and alcohol) stationary liquid is adopted in the fixation, and the stationary liquid consists of formalin, acetic acid and 30% alcohol (formalin:acetic acid:30% alcohol = 1:1:18). The method is adopted, so that the disadvantage of much youngness of the fern gametophytes can be effectively overcome; the fixation can be well performed for cell divisions at all stages; from a paraffin section in a later stage, a plurality of mitotic sections can be observed, so that a whole development process can be reflected detailedly; therefore, the method has high development and application values.

Description

technical field

[0001] The invention relates to a method for paraffin sectioning of plants, in particular to a method for paraffin sectioning of fern gametophytes. technical background

[0002] To date there is no technique specifically applied to the preparation of fern sections, and conventional paraffin sectioning techniques are commonly used to prepare dissected sections of ferns. However, the conventional paraffin section technique will cause the fern gametophyte to lose water, severely deform and change the internal shape of the cell, and the anatomical structure of the gametophyte cannot be observed normally through the conventional paraffin section technique. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for paraffin sectioning of fern gametophytes, including drawing and fixing, washing, dyeing and bluing, dehydration and transparency, wax dipping and embedding, sectioning, patching, dewaxing a...
