Simple physics may limit the size of leaves
WebbIn words, this idea can be expressed in two ways: (1) growth rate is determined by plant size. (2) the growth rate, expressed per unit of plant, is a constant. In mathematical terms these two statements are: (1) growth rate = ∆S/∆ t = k * S, where ∆S/∆ t is the growth rate, the change in size divided by the change in time, S is the ...
