Abstract

Results of microcalorimetric studies of water crystallization in some plant tissues are presented. It was shown that in each tissue water is crystallized in a specific temperature region and the process is independent of water crystallization in other tissues. Besides this water fraction, there exists another one in the tissues which is united in a single system. The latter is crystallized simultaneously throughout the preparation. It is suggested that this water fraction is located in the tissues intercells. Results of secondary water crystallization in plant tissues are presented. It is shown that after freezing and thawing the core cells are damaged more strongly.

摘要

本文展示了对某些植物组织中水结晶的微量热研究结果。结果表明，在每个组织中，水在特定温度区域结晶，且该过程与其他组织中的水结晶无关。除了这部分水，组织中还存在另一种处于单一系统中的水。后者在整个制剂中同时结晶。研究表明，这部分水位于组织细胞间隙。本文还展示了植物组织中二次水结晶的结果。结果表明，冷冻和解冻后，核心细胞受损更严重。
