Flowering and fruiting

• Guava tree flowers throughout the year, but the peak flowering is observed in 2 season, rainy crop (April-May) and winters crop (Aug- Sept).
• Flowers are produced in leaf axils or in cyme the period of flowering varies from 25-45 days.
• Honey bees are the pollinators.
Flower regulation

• Bahar treatment expand, root exposure, with holding water and also deblosoming the rainy season crop due to insipid taste of the fruits and inferior quality.
• So winter crop is generally desirable.
Fruit set

• Only 35-50% fruits are carried to maturity though initially 80-86% fruit sets.
• In seedless variety, it is as low as 6 per cent to improve fruit set, GA3 at 200ppm.
• Fruits take 105-140 days to mature from fruit set.
• Spraying GA3 at 1000-8000 ppm is suggested to improve fruit set.
