Role of Water Potential in Microbial Growth and Development of Plant Disease, With Special Reference to Postharvest Pathology
1
Abstract
The subject of water relations in microbial growth and development of plant disease has been reviewed extensively (11, 13, 14, 18, 19, 28, 34), as has the subject of water relations of wood decay and growth of wood-decay fungi (20). This paper will not duplicate earlier reviews, except as necessary to present some basic principles. Our paper has 5 parts: 1) the water potential concept; 2) methods to measure water potential; 3) water potential requirements for growth of bacteria and fungi; 4) water potentials of the tissues of some fruits and vegetables after harvest; and 5) water potential and the development of disease.
