摘要:

结合番茄叶片结构特点,采用6种表皮制片技术对番茄叶片下表皮进行装片,并对不同方法的制片过程和观察效果进行比较研究。结果表明,番茄叶片薄,表皮为单层细胞,其上着生有丰富表皮毛,下表皮与疏松的海绵组织相邻;表皮撕取法和透明胶带粘取法可以真实地观测气孔大小、密度等静态性状指标和气孔开度等动态行为;因番茄叶柔软,刮片法对操作要求极高,而解离法不但用时长且效果不佳,都不适宜番茄叶下表皮制片;可撕拉型指甲油印迹法能获得气孔指数和气孔开度的印痕,但对叶片有一定损坏,而硅胶-指甲油双阶段印迹法对叶片没有损伤,可以多次印迹同一叶片相同部位,连续观测气孔运动及发育等动态行为。研究结果可为不同研究选择适合的番茄叶表皮制片方法提供依据。

Abstract:

This paper adopted six kinds of leaf epidermis slice techniques to treat lower epidermis of tomato leaves considering their structural characteristics, and compared the preparation process and observation effect of different techniques. The results show that tomato leaves are thin, the epidermis is single-layer cell with abundant epidermal hairs, and the lower epidermis is adjacent to the loose spongy tissue. Static characteristics, such as dynamic behavior of stomatal size, density and stomatal aperture, could be observed by skin peeling method and cellophane tape sticking method. Due to the softness of tomato leaves, the scraping method is extremely demanding to operate, and dissociation method is time-consuming and has poor effect, both the techniques are not suitable for the slice production of tomato leaf epidermis. Tearable nail oil blotting method could obtain the imprint of stomatal index and stomatal aperture, while the leaves would be damaged certainly. Silica gel-nail polish two-stage blotting method has no damage to the leaves, the same part of the same leaf could be imprinted continuously without scathe, and in this way, the dynamic behavior like stomatal movement and stomatal development could be observed continuously. The results could provide a basis for selecting suitable tomato leaf epidermis preparation methods for different research purposes.
