Abstract
The cytoplasm of the interior of maturing pine tracheids is revealed by scanning electron microscopy as a lamellate and filamentous intravacuolar reticulum immersed in vacuolar sap. Formation of cytoplasmic spherules and the breakdown of the cytoplasmic reticulum initiate protoplast disintegration that terminates in tracheid maturation. The process is believed to involve vacuolar membrane transformations.
摘要
通过扫描电子显微镜观察发现，成熟松树管胞内部的细胞质呈现为一种片状和丝状的液泡内网状结构，浸没在液泡液中。细胞质小球的形成和细胞质网状结构的解体引发原生质体解体，这一过程最终导致管胞成熟。据信该过程涉及液泡膜的转变。
