A study was carried out to selected physiological and
biochemical characteristics of Syzygium samarangense
for their physiological and biochemical characteristics at
Functional Food Laboratory, University of Malaya, Kuala
Lumpur. Various physiological and biochemical parameters
were monitored during two seasons of fruit growth between
October, 2009 to August, 2010 with the ‘Giant green’, ‘Masam
manis pink’ and ‘Jambu madu red’ cultivars of S.
samarangense. Ripened fruits of the different cultivars
were collected from the experimental field of Banting,
Selangor and analyzed for selected physiological parameters
namely chlorophyll fluorescence, quantum yield, fruit
weight, total yield, number of seed per fruit, seed weight
and dry matter content and some biochemical parameters that
is, juice content, pH, total soluble solids (TSS), glucose,
fructose, inverted sugar, ethanol, total flavonoids, phenols
and anthocyanins content. It was observed that highest
chlorophyll fluorescence, maximum quantum yield (0.79),
fruit weight, seed number (4) and seed weight per fruit
(4.56 g) were in the ‘Giant Green’ cultivar while total
yield, glucose (9.83%), fructose (9.9%), inverted sugar
(9.57%), ethanol (20.5%), flavonoids (914.1 mg/100g) and
phenols (326.67 mg GAE/100g) were in the ‘Masam manis pink’
cultivar, and the highest juice content (76.33 ml), highest
total soluble solids (8.76ºBrix) and anthocyanins (2.78
mg/L) were in the ‘Jambu madu Red’ cultivar. From this
study, it can be concluded that ‘Masam manis pink’ and
‘Jambu madu red’ cultivar are comparatively better than
‘Giant green’ cultivar under South Asian conditions.
