Researches on plant metabolism. I. Respiration and sugar absorption by storage organs in relation to time and thickness of tissue slices

Researches on plant metabolism. I. Respiration and sugar absorption by storage organs in relation to time and thickness of tissue slices

Bull Fac Sci Fouad I Univ 24: 32-60

Expts. are reported in which tissue slices of varied thicknesses from carrot and radish roots were washed in water and then floated on sucrose solns. Sucrose was always hydrolyzed in the culture medium before its absorption by the tissue slices, the rate of hydrolysis being greater in the media of thinner slices. Discs thicker than 1 mm. showed decreasing respiration and sugar absorption. In slices thinner than 1 mm. the respiration and sugar absorption were controlled by 2 opposite factors: (a) the availability of the atmospheric O2 to the surface cells tended to increase the respiration and sugar uptake, and (b) the increase in the proportion of injured to intact cells in the thinner slices would tend to diminish the metabolic activity of these discs; the effect being greater on sugar absorption than on respiration. The duration of the washing period had a great effect on the subsequent CO2 output and sugar uptake. Slices washed in water for short periods always gave higher values of respiration and solute uptake. Such high values were attributed to the intervention of the wound-healing metabolism.
