Effect of thermal stress on the liberation of tetraspores from Gelidium pusillum (Stackhouse) LeJolis, PterocladiLl heteroplatos
(Boergesen) Umamaheswara Rao and Kaliaperurna.l and Gelidiopsis variabilis( Greville) Schmitz was studied.
in response to temperatures lower (0° -lOOC)and higher( 40° -45°C)than the tolerance limits of plants. Spore liberation was
seen in these algae exposed to low and high temperatures for short durations but the output decreased with increase in the
duration of treatment. The temperature tolerance capacity varied in the algae tested
