AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively remove the interference of epidermal hairs on the leaves of *Quercus variabilis*, resulting in low-quality sample preparation for stomatal observation. Furthermore, scanning electron microscopy is time-consuming and requires expensive equipment.

Method used

The process involved selecting standard sample leaves and marking leaf positions, vacuum-assisted fixation, directional scraping of epidermal hairs under microscopic monitoring, mild alkaline digestion of the mesophyll, specific staining, and gradient dehydration to ensure the consistency of the physiological state of the samples and the clear visualization of the stomatal structure.

Benefits of technology

It achieves clear visualization and integrity of pore structure, ensures sample repeatability and high-definition imaging, solves the problems of sample variability and uneven fixation in traditional methods, and provides a reliable morphological basis.

Abstract

本发明涉及栓皮栎叶片样品技术领域,特别是一种栓皮栎叶片气孔观察样品的制备方法,包括如下步骤:采集植物叶片样本并保存于FAA固定液;样本叶片永久装片的制作:首先刮除样块表皮毛,之后置于10%溶液中煮沸28‑32min,30%NaClO溶液漂白5‑8min,0.5%番红溶液染色1min,再经50%、95%、100%乙醇梯度脱水5min,二甲苯透明5min,中性树脂封片,最后自然晾干后40倍光学显微镜下观察并拍照。本方法易于掌握且成功率高,制备的装片可长期保存,观察到的气孔形态清晰可辨,可用于气孔面积、气孔密度等性状的测量。
