Plants were defoliated at 1- or 2-week intervals during each growth cycle, and values are the least squares means of shoot dry weight during that growth cycle at both locations ± se of the mean; n is the number of observations. The values between control and transgenic plants were not significantly different at the 5% level of probability at any growth cycle at either location.
