As the salt concentration increased further (hypertonic), the process was reversed which resulted in further plasmolysis of the green pepper cells, thereby drastically reducing its moisture content, hence, reduced drained weight.
Plasmolysis also occurred when WG gametophytes were exposed to slow increases in NaCl (Fig.
Studies by Greenhill (1964) indicated that plant cell breakdown and the release of plant juices by plasmolysis is a prerequisite for the development of the LAB during the early stage of ensiling.
