No full textEmbedding thin plant specimens for oriented sectioning
No full textSmall plant structures such as small primary roots, filamentous mosses and algae are difficult to orient for sectioning since they become wavy and curl during embedding. A method is described for embedding and orienting tiny plant specimens in a glycol methacrylate resin using self-constructed flat molds. Prior to sectioning, small samples can be oriented in both the longitudinal and the transverse plane. As several samples can be sectioned simultaneously, time-consuming trimming of the blocks is reduced substantially. The efficiency of this technique has been demonstrated using the tiny roots of the model plant Arabidopsis thaliana (L.) Heynh
