[Process of water crystallization in plant tissues].

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.
