Última A SURVEY OF HETEROCYSTOUS NITROGEN-FIXING CYANOBACTERIA IN CHILEAN RICE FIELDS Gayana Botánica Pereira,Iris; Moya,M; Reyes,G; Kramm,V. The purpose of this study was to increase knowledge of the nitrogen-fixing cyanobacteria communities of Chilean rice fields. To this end, we sampled 34 rice fields situated between latitudes 34° 30' and 36° 36' S in central Chile. At each site, two water samples and one soil sample were taken. Samples were fixed in 4 % formalin before taxonomic determination. A total of 12 filamentous heterocystous taxa were determined, nine of which have not previously been recorded in Chile. For each taxon, a description based on morphological and reproductive characters was made and recorded along with information on the geographical distribution in the study area Tipo: Journal article Palavras-chave: Anabaena; Aphanizomenon; Cylindrospermum; Gloeotrichia; Nostoc.
