| The present work is a population morphometric study of Gracilaria from different environments along a latitudinal gradient of the Chilean coast that cover 1,500 km. Gracilaria species have been extensively exploited with an average extraction of 75,000 t per year. In Chile this seaweed is usually found in sandy bottom bays between Antofagasta (23º29'S - 70º25'W) and Chiloé (42º03'0''S - 73º11'0''W). Observations were made in 51 plants. Macroscopic observations were done in fresh plants, microscopic characters were determined in transversal sections with 20% Karo syrup and stained with aniline blue. Numerical analyses were performed by one-way ANOVA and Principal Component Analysis. The latter analysis was performed for those characters with significant... |
