FIGURE 1.

Transpiration rate (A) of wounded and unwounded (control) tissues and relative weight (B) of wounded and unwounded (control) roots during 28 days storage at 6 and 12°C. Roots were wounded by abrading the root surface with a wire brush 2 h after harvest and were subsequently stored at 94% relative humidity. Transpiration rate was measured as the rate of water lost from tissue disks from the surface of wounded or control roots. Relative weight was the weight of roots relative to their weight on the day of harvest after wounding. Data are the mean ± SE of the mean. For transpiration rate, n = 5; for relative weight, n = 8.
