Response of three-year old Mu-Legacy and nontransgenic ‘Legacy’ plants to different chilling hours in the greenhouse at 22–24 °C under natural light conditions. These plants (n = 5) were grown under normal chilling conditions (> 1000 chilling hours) before they reached three-years old. The primary y-axis is for the column chart and the secondary y-axis is for the line chart. Each data point is a mean of five plants. Significant changes determined using a Student’s t-test are denoted. Asterisk (**) indicates p < 0.01
