Description 50-54
Experiments were carried out with tetrasporophytes of Padina boergesenii
to understand the effects of ultra violet radiation, light intensity,
photoperiod, temperature, salinity and desiccation on the liberation of
tetraspores. UV-B radiation inhibits spore liberation while UV-C radiation
enhances spore release. UV-A radiation increases spore liberation initially during
short time exposure and inhibits spore release during long time exposure. UV-B
radiation combined with day light increases the spore liberation. Low
illuminance ( 26 μEam-2s-1), short day (8:16 hr LD) and submerged
condition of plants and seawater of 35 ppt salinity and 20° C temperature were
found to be favourable for maximum liberation of tetraspores. Temperature shock
(ranges from 0° C to 50° C up to 120 minutes) could not enhance the spore
discharge in Padina boergesenii.
