Description 270-273
Gracilaria
verrucosa (Huds.) Papenfuss was collected monthly for a period of two years
from the backwaters of Muttukadu, Madras, Tamil Nadu and the agar extracted
from it was quantitatively and qualitatively analyzed to explain the

effect of environmental
variables on its yield and quality. Salinity and temperature contributed to
much of the variations in gel strength and yield of agar and the variations were
seasonal. Gelling and melting temperatures of the agar ranged from 35 to 41°C
and 67 to 76°C respectively. Gel strength (94 g cm-2) was maximum in
samples collected during summer when agar yield was low. It may be concluded
that low water temperature may be a requisite for high gel strength, and low
salinity for good agar yield.
