(a) Lateral root formation and (b) shoot size for Ws seedlings grown for 15 days on control media supplemented with varying amounts of the non-metabolizable sugar mannitol. n = 46–50 for all data points. For shoot size, comparison between control and all other mannitol concentrations was statistically significant at p < 0.01 using Student's paired t-test. For TOT, comparison between control and all other mannitol concentration was statistically significant at p ≪ 0.01 using Student's paired t-test. Standard error is shown.
