Other claims from this paper (9)
- Intervention effect Plasmolysis retarded cucumber-cell killing by pathogen enzyme preparations much more than maceration.
- Intervention effect Plasmolysis retarded turnip-cell killing by pathogen enzyme preparations much more than maceration.
- Observation Cells recovered from plasmolysis regained sensitivity to toxic action.
- Intervention effect Plasmolysis greatly reduced toxicity of mercuric chloride to plant cells.
- Intervention effect Plasmolysis greatly reduced toxicity of oxalic acid to plant cells.
- Association Acetone fractionation across pH produced enzyme preparations varying in activity, with macerating and toxic actions varying together.
- Intervention effect Partial maceration made plant tissues much more sensitive to mercuric chloride toxicity.
- Mechanism The authors interpret maceration as allowing a toxic principle to reach and damage the protoplastic surface before maceration is complete.
- Mechanism The authors support the view that pathogen enzymes that macerate host walls also kill protoplasts.
