Fruit development
The pineapple has three distinct phases of growth : the vegetative phase of leaf growth, the generative phase of fruit growth , and another vegetative phase of shoot growth. These three phases overlap to a certain extent. The leaf growth continues even after bloom has been induced and stops only after the inflorescence has appeared. Further , shoot growth may start before the fruit is harvested The flowering , fruit growth and development of pineapple had been recently reviewed Natural inflorescence development is initiated by shortened day length and cool night. However , growth regulators are used commercially to force flowering Pollination is not required for fruit development. In the self – incompatible commercial cultivars, the fruit develops parthenocarpically.
