  1. aOverall average of the days of onset of flowering, in 30 transgenic tomato plants of each group.
  2. bAverage number of fruits per plant in 30 transgenic tomato plants of each group.
  3. cAverage dry weight of 30 transgenic tomato plants of each group of plants.
  4. dAverage number of seeds (per gram of fruit) in eight fruits of individual transgenic plant, in 30 plants of each group.
  5. Values in parenthesis indicate the probability associated with a student’s paired t-test with a two tailed distribution. When P < 0.05 the difference of the individual parametric value to that of the value of the control was significant.
