Abstract
The purpose of this research was to apply measurement of soluble solids content (SSC) which is an important noticeable change to describe the growth during ripening of longan fruits (Biaokhiao cultivar) in order to contribute to the phenology studies and the information can help assist the development of longan management and control protocols. It was found that the SSC increased rapidly in parallel with enhancing fruit size and maturity until around week 27 after floral emergence. At the end of the ripening process, it reached the maximum level at 25.07±1.21 ºBrix when the longan fruits were around 95% of the final size. After that, SSC started to significantly and quickly decrease even though the fruit size was still slightly growing.
