Seasonal variation of carrageenans in tetrasporic, cystocarpic and 'sterile' stages of Gigartina skottsbergii S. et G. (Rhodophyta, Gigartinales)

Cystocarpic and 'sterile' plants of Gigartina skottsbergii produce χ-carrageenans, while tetrasporophytes produce λ-carrageenans. No seasonal variation in the carrageenan yields in the three stages was evident. Yields were clearly higher in cystocarpic (34.1-64.7%) and 'sterile'...
