Table 2. Absolute values and treatment effect (TE) between control and drought recovery seedlings for the soluble sugar and starch concentrations at the end of the drought period and after a 27-d recovery period.
Values are treatment averages ± se; n = 5 to 8 per tissue and treatment. –, Treatment effects do not apply to control data.
