Abstract
The present research was conducted to investigate the effect of
direct sun-light on color development of seedless barberry fruit.
The selected orchards were in different locations (with different
altitude). On some trees, some inflorescences were chosen to
cover as bagged (excluded from direct sun-light). Some cases
also used as non-bagged. Bagging was done in different times
during growing season. Results showed that in all regions, day
temperatures were higher than 20°C, and night was lower than
30°C. The lowest difference of day-night temperatures observed
in Marvak. Bagging showed a significant effect on anthocyanin
(ant), hue angle (h*), lightness and redness (a*). Bagging time
significantly influenced chroma (C*) and b/a values. Ant, C*, a*,
and a/b values significantly affected by location characteristics
specifically altitude, and the highest ant and a* value observed
in Marvak. In all locations, the highest value of ant and h*
observed with not-bagged fruits. The highest value of a*
obtained in not-bagged fruits. It is concluded that direct sun is
needed for color development of barberry fruits, however,
night-cool temperatures also are important for anthocyanin
accumulation of this fruit.
