  1. aAverage number of days for onset of flowering from seed sowing, in 20 transgenic tomato plants of each line.
  2. bAverage number of fruits per plant in 20 transgenic tomato plants of each line.
  3. cAverage number of seeds (per gram of fruit) in eight fruits of individual transgenic plant, in 20 plants of each line.
  4. dDry weight of 20 transgenic tomato plants of each line.
  5. *Values in parenthesis indicate the probability associated with a student’s paired t-test.
  6. When P<0.05 the difference of the individual parametric value to that of the value of the control was significant.
