  1. 1 LFE = last fully expanded leaf, M-I2 = meristem to internode 2, I4-5 = internodes 4 and 5, I7-8 = internodes 7 and 8, LI = lowest internode.
  2. 2Data are presented as mean values (n = 3). Between treatment and control for each type of sugars, numbers with different letters are significantly different based on Student t-test (P ≤ 0.05)
