Agar yield and gel strength of Gracilaria heteroclada collected from Iloilo, Central Philippines

Abstract

Seasonality of yield and gel strength of agar from Gracilaria heteroclada was determined. Gel strength was high (510-794 gm cm^-2) during early dry season (October-March) and low (43-101 gm cm^-2) during the wet season (May-August). A negative correlation exist (P ≤ 0.05) between agar yield and gel-strength.
