It is common knowledge that for a given cultivar of Easter lily, small bulbs grown at the same location as large bulbs produce fewer flowers when forced into bloom. In a recent test at U. C. Davis, as an example, 30 gram bulbs produced 4.5 flowers per plant, while 80 gram bulbs of the same variety grown and forced exactly the same produced 8.9 flowers per plant. Bulbs of intermediate weight produced an intermediate weight produced an intermediate number of flowers. Somewhat less well known is that the number of leaves produced by the single apex of the lily plant per unit time is likewise directly proportional to bulb size. In the experimental Work reported in this paper, for instance, he increase in leaf count in 100 days was found to be directly and linearly proportional to the bulb size (Figure 1).
