The genus Gracilariopsis (Rhodophyta, Gracilariales) in the Philippines: morphological and taxonomic confirmations
(University of San Carlos, 1998)
Reports of the economically-important agarophytic seaweed genus Gracilariopsis Dawson from Philippine waters are verified for the first time. Cystocarpic, spermatangial and tetrasporic materials collected from various ...
Biomass and reproductive states of Gracilaria heteroclada Zhang et Xia collected from Jaro, central Philippines
(Walter de Gruyter, 1996)
Biomass production and reproductive states were investigated to determine the abundance of Gracilaria heteroclada Zhang et Xia at Jaro, central Philippines from March 1990 to February 1991. Biomass of Gracilaria heteroclada ...
Assessment of some agarophytes from the coastal areas of Iloilo, Philippines. I. Seasonal variations in the biomass of Gracilaria changii, Gracilaria manilaensis and Gracilariopsis bailinae (Gracilariales, Rhodophyta)
(Walter de Gruyter, 1996)
Monthly biomass (g dwt m<sup>-2</sup>) of Gracilaria changii, G. manilaensis and Gracilariopsis bailinae collected in four different coastal areas of Iloilo, Philippines showed significant differences. Gracilaria changii ...
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. ...
Influence of extraction time on the rheological properties of agar from some Gracilaria species from the Philippines
(Walter de Gruyter, 1992)
The influence of extraction time on the clean anhydrous yield, rheological properties, dynamic gelling and melting temperatures of 1.5% agar from six species of Gracilaria and one species of Gracilariopsis collected from ...
New records of a marine macrobenthic algae of Panay and Guimaras Islands
(Science and Technology Information Institute, 1992)
Thirty new records of macrobenthic algae for Panay and Guimaras Islands are reported, consisting of 12 species of Chlorophyceae, 4 Phaeophyceae and 14 Rhodophyceae.
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 ...
The interactive effect of some environmental factors on the growth, agar yield and quality of Gracilariopsis bailinae (Zhang et Xia) cultured in tanks
(Walter de Gruyter, 1997)
The single and interactive effects of light and temperature, salinity, and urea enrichment on the growth and agar yield and quality of Gracilariopsis bailinae were determined under indoor and outdoor tank conditions. Culture ...
