Abstract
Under the influence of high
hydrostatic pressure the thalli of focus vesiculosus L. release macromolecules. Which undergo a slow disintegration even after the removal of pressure . the amount of exudation is directly proportional to the length of incision given n the thallus. The excretion of organic substances increases with the rising pressure intensity (200 to 1000 atm) as well as the duration of its action (
1 to 10 hours). Temperature acts antagonistically to the pressure effects . the quantity of released macromolecules decreases with the increase in temperatue (50 to 300C). high temperatures (400C) however, intensity the pressure effects.
