Abstract
Progressive increases in daughter bulb weight provide an accurate estimate of growth rate, and with duration of period of constant growth, determine bulb size potential.
Time of floral initiation in the mother axis provides an accurate estimate of growth period potential.
Large yields of bulbs have generally been associated with near or above-normal spring temperatures which increase the rate and duration of constant growth.
Early bulb maturity, based on numbers of daughter leaf primordia and time of daughter axis elongation, also is associated with earlier and longer growing seasons.
However, daughter leaf primordia numbers are not closely correlated with daughter bulb weight.
