Growth rate, yield and economics of Gracilariopsis bailinae (Gracilariales, Rhodophyta) using fixed bottom long-line method
(Science and Technology Information Institute, 1997)
Vegetative thalli of Gracilariopsis bailinae weighing 10 g each were tied to a 5-m monofilament line with plastic strips and laid horizontally on the substrate and were observed to grow at 30 d interval for 9 months. The ...
Harvesting Gracilariopsis heteroclada (Gracilariales, Rhodophyta) in Iloilo, Philippines
(Science and Technology Information Institute, 1993)
Gracilariopsis heteroclada thalli were planted in a 1 m2 ditch along a drainage canal at Leganes, Iloilo, Philippines. Monthly growth rate and production were calculated to determine the effect of harvesting on the ...
Agar production from Gracilariopsis heteroclada (Gracilariales, Rhodophyta) grown at different salinity levels
(Walter de Gruyter, 1994)
Gracilariopsis heteroclada grown in fiber glass tanks at four salinity levels was treated with three different concentrations of aqueous NaOH. Yield, gel strength, gelling and melting temperatures of the extracted agar ...
Laboratory manipulation of Gracilariopsis bailinae Zhang et Xia (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1997)
Carpospore germination, carposporeling development and tetraspore formation were investigated in Gracilariopsis bailinae Zhang et Xia by manipulating photoperiod, photon flux density, temperature, salinity and nutrients. ...
Rheological properties of agar from Gracilariopsis heteroclada (Zhang et Xia) Zhang et Xia (Gracilariales, Rhodophyta) treated with powdered commercial lime and aqueous alkaline solution
(Walter de Gruyter, 1992)
Rheological properties were measured for 1.5% agar gels from Gracilariopsis heteroclada pre-treated with powdered commercial lime (CaCO<sub>3</sub>) during sun drying, and a combination of two alkaline solutions during ...
