Method for observing morphological structure in mesophyll of fossil plant

Abstract

The invention provides a method for observing a morphological structure in mesophyll of a fossil plant. The method adopts means of immersing a fossil in distilled water, 40% hydrofluoric acid, Shu liquid and an alkaline solution successively, thereby removing impurities from the epidermis of the fossil; and then a mesophyll substance is separated independently through a sucker or a pipette for observation and identification. According to the method, the morphological observation and determination on the mesophyll in each experimental procedure are controlled to improve extraction of morphological character and function information of the plant, thereby providing reliable information materials for further identification on fossil plant leaves.

Description

technical field [0001] The invention relates to the technical field of geology, in particular to a method for observing the internal morphological structure of fossil plant mesophyll. Background technique [0002] The mesophyll of modern plants contains a large number of structures and substances, which are of great significance in the identification of plants, such as the camphor extracted by humans, that is, the oil cells from the Lauraceae plant tissues, and the observation of oil cells in modern plants With the help of a microscope or an electron microscope, because the leaves of modern plants come from a wide range of sources, the methods of processing plant leaves are relatively mature, and the method of observation is relatively simple. [0003] However, there are few reports on the structure in the mesophyll of fossil plant leaves formed in geological periods, and they are only scattered in foreign references. In China, there are only reports and studies on Eucommia ...

Problems solved by technology

[0003] However, there are few reports on the structure in the mesophyll of fossil plant leaves formed in geological periods, and they are only scattered in foreign references. In China, there are only reports and studies on Eucommia gum silk, and the description of its experimental methods is relatively simple. The experimental method is also an experimental procedure and method formulated to observe the morphological and structural characteristics of the leaf epidermis of the plant

[0004] Existing technology is mainly aimed at the observation and separation of the morphological structure of the upper and lower epidermis cells and stomata of plants, but the material between the upper and lower epidermis is treated as impurities, and no attention has been paid to it. Therefore, the upper and lower epidermis of plants contains The morphological structure substances with identification significance are rarely reported, and the description of its experimental methods is relatively simple and unsystematic, lacking detailed information and references.
