Abstract

Random samples of guava flowers were observed to determine the gross morphology and biology of the flowers, including fruit set and development. The guava flower is either solitary or in groups of two in the leaf axils. It is white and is about 2.5 to 3.0 cm. in diameter. It has four or five petals and numerous stamens which around the light yellow style. It took 24-26 hours from the sepal splitting to full flower opening. Flower opening started at around 5:30 AM and was completed by 6:00 AM. Stigmatic receptivity occurred at flower opening up t 24 hours thereafter. Receptivity was in its maximum an hour after flower opening (7:30 AM.). Anther dehiscene, which started at 6:30 AM, continued until 5:30 in the afternoon. Hand pollination resulted to 79.62% fruit set while open and controlled pollination resulted to 87.12% and 82.65% fruit set, respectively, Fruits reached maturity 11weeks after pollination. The fruit turned from dark green to light green in color when it reached maturity.
