Abstract

Vernalization of germinating endive seed or of young endive plants hastened floral initiation, but at the expense of vegetative growth. High temperatures after vernalization promoted bolting. Long days hastened bolting in both vernalized and non-vernalized plants, again at the expense of vegetative growth. A limited period of short days immediately after sowing also promoted flowering, and it is suggested that such short-day treatment may act as a partial substitute for low temperature. High light intensity had a supplementary effect in promoting bolting but, in contrast to vernalization and long days, caused more rapid vegetative growth than low light intensity.-Lab.
