WebSome evidence suggests that the differences in the organic osmoticum used may relate to the different inorganic ion contents of the plants. The accumulation of nitrogen dipoles as cytoplasmic osmotica may make heavy demands on the nitrogen economy of the plants and this problem is discussed briefly. WebAug 1, 1981 · It is likely that the alliinase liberated into the cytoplasm-osmoticum from burst vacuoles had already begun to degrade the alkyl cysteine sulphoxides from the cytoplasm. Both alkyl cysteine sulphoxides and alliinase were readily soluble in the aqueous osmoticum.
