摘要: Abstract Nostoc flagelliforme is an edible blue–green alga with herbal and dietary values. Due to the diminishing supply of natural N. large investment on development its cultivation technology, it anticipated that artificially cultured will soon sustain market supply. Once this change occurs, storage-associated quality problem become focus attention for future trade. In paper, we used a chlorophyll fluorescence parameter, maximum quantum efficiency Photosystem II (Fv/Fm), several biomarkers evaluate samples. It was found longer storage times resulted in darker coloured solutions (released pigments) decreased amounts (Chl a) water-soluble sugars (WSS). Additionally, higher Fv/Fm value suggests better physiological recovery quality. actual application, determination would be first step evaluating flagelliforme, biochemical indexes serve as good secondary markers.
