Description

TECHNICAL FIELD

[0001] The utility model relates to a tobacco leaf lamina ultramicrostructure sampler belongs to tobacco sample sampling detection technical field. BACKGROUND

[0002] Tobacco is a widely planted economic crop in China, and the main tobacco variety type in China is flue-cured tobacco. In the growth and curing process of tobacco, with the in-depth research on tobacco growth and development, adversity stress, quality formation and style characteristic highlighting, tobacco leaf lamina ultramicrostructure sampling and observation become the key to biological analysis.

[0003] In the research of tobacco growth and development, by observing the ultramicrostructure of leaf lamina at different growth stages, the dynamic change process of cell division, differentiation and organelle can be revealed. For example, in the tobacco seedling stage, observing the initial structure of leaf lamina cells and the development of chloroplasts helps to understand the early establishment mechanism of photosynthesis. In the vigorous growth period, analyzing the expansion of leaf lamina cells and the thickening process of cell wall can provide structural basis information for tobacco biomass accumulation.

[0004] For the research of tobacco quality formation, ultramicrostructure is closely related to the accumulation of chemical components and the synthesis of aroma substances in tobacco leaves. The number, size and distribution of organelles such as chloroplasts (starch granules) and protein bodies in tobacco leaves differ in different quality tobacco leaves. The formation process of high-quality tobacco leaves may have a more reasonable cell tissue structure, which is beneficial to the synthesis and storage of substances such as sugar and nicotine. Through ultramicrostructure sampling and observation, the root of these differences can be explored to provide a basis for improving tobacco quality.

[0005] Analyzing the changes of leaf lamina ultramicrostructure of tobacco under adversity (such as drought, high temperature, pests and diseases, etc.) helps to clarify the resistance mechanism of tobacco. For example, under drought stress, observing the dehydration of leaf lamina cells, the morphological changes of chloroplasts and the integrity of membrane structure can help understand how tobacco adjusts cell structure to adapt to water-deficient environment, providing a reference for breeding resistant tobacco varieties.

[0006] In the traditional sampling of tobacco leaf lamina ultramicrostructure, cutting is generally done by hand-held blade. However, this sampling method is less safe, time-consuming and laborious, and may cause the width of the sampled sample to be inconsistent, which greatly affects the experiment, and it is not convenient to sample leaf lamina in different states, so it is necessary to provide a precise sampling method for leaf lamina in different states, which can conveniently and quickly obtain the required sample.
