Osmolality and carbohydrate content of SL cells as affected by aluminium

Treatment	Osmolality (mOsm kg−1)	Starch (pg cell−1)	Soluble sugar (ng cell−1)	Glucose (%)	Fructose (%)	Sucrose (%)
Initial	262±17	75±2	1.22±0.07	32±3	35±3	12±2
Control	260±4	88±3	2.34±0.05	32±2	36±2	16±3
Al (50 μM)	205±3	65±3	0.40±0.02	34±1	38±1	8±1

Cells at the logarithmic phase of growth (Initial) were treated without (Control) or with aluminium for 18 h. The values for starch and soluble sugar are expressed as glucose equivalent per cell, based on the cell number data shown in Table 1. Sugar refers to soluble sugar. Glucose, fructose, and sucrose levels are shown as percentage (w/w) of the total soluble sugar content. Data show the mean ±SE from three replicate experiments.
