| The
effect of 3 temperature regimes (31/25 (warm), 25/19 (moderate) and
19/13 deg C (cool), day/night) on flowering and pollination in 4 mango
cultivars (Haden, Irwin, Keitt and Local) was investigated in Taiwan.
Compared with the moderate treatment, warm temperatures hastened growth
rates of panicles and flowers, shortened flowering duration and life
span of individual flowers, and decreased the number of hermaphrodite
and male flowers. Warm temperatures increased the rates and percentages
of anther dehiscence and pollination. In contrast, cool temperatures
retarded the growth of panicles and flowers, extended flowering duration
and life span of flowers, and increased the number of hermaphrodite and
male flowers. Sex ratio was statistically not different among the 3
temperature treatments. The highest number of hermaphrodite flowers
occurred during the first third of the flowering period. The highest
number of male flowers occurred halfway through the flowering period. |
