The effect of ionic osmotic potential (Ψ<SUB>π</SUB>), and matric potential (Ψ<SUB>m</SUB>) in the range of -0.2 to -4.0 ㎫ on mycelial growth of three species of Pleurotus (P. florida, P. ostreatus and P. sajor-caju) were determined over a range of temperature (15-30℃) on a 2% malt extract agar medium and compared with the Ψ<SUB>π</SUB> effect on growth of two strains of Trichoderma green mould. With the ionic solute KCl, optimun Ψ<SUB>π</SUB> for growth was -0.2 ㎫ for P. florida and in the range of -0.2 to -0.5 ㎫ for P. ostreatus and P. sajor-caju. The growth of all the species decreased significantly below -1.5 ㎫, with slight growth at -3.0 ㎫ and with no growth at -4.0 ㎫. Of the species of Pleurotus, P. florida grew significantly slower than the other two species. Growth of the species of Pleurocus was significantly slower when water potential (Ψ<SUB>∞</SUB>) was modified matrically with polyethylene glycol (PEG) 8000 then osmotically with KCl. They were also more sensitive to changes in Ψ<SUB>m</SUB> than Ψ<SUB>π</SUB>. The optimum Ψ<SUB>m</SUB> of the Pleurotus was -0.5 Ψ<SUB>m</SUB>, with no growth below -3.0 ㎫. Of the species of Pleurotus, P. florida was most sensitive and P. sajor-caju was more tolerent to lowered Ψ<SUB>π</SUB>, but P. sajor-caju was most sensitive to lowered Ψ<SUB>m</SUB>. The growth rate of the Trichoderma green mould strains was much faster than that observed for the Pleurotus spp. Optimum growth for both strains of Trichoderma was in the range of -0.2 to -0.5 ㎫. Strain CNU 503 was more tolerant to water stress than strain CNU 501. Both strains were able to grow up to 30% of optimum growth at -4.0 ㎫ at 25-30℃.
