Abstract
THERE has long been divergence of opinion as to whether or not the flowering of seedling trees, especially pome fruits, could be hastened by cultural practices or through environmental changes. At the California Institute of Technology, it was found with Pinus that the ‘juvenile’ or initial non-flowering period of the seedling's life could be shortened following artificial lengthening of the period of summer growth and prolonged winter dormancy1. In apples, any treatment that restricts or retards growth has been held by some to delay the onset of reproductive ability, while others have held the contrary view2,3.
