Sample text

These results which have just been discussed had for their object the presentation of the complete diurnal curve of acidity under the natural conditions which surround the plant, the complete course of which has not been plotted in a detailed fashion for any succulent plant. The oscillations in acidity are known to be affected most importantly by light and temperature, and a number of experiments were far as possible, as is made in which these two factors were isolated as set forth below. EFFECT OF LIGHT ON ACIDITY.

This depression of temperature should be ascribed to transpiration, although the activity of cacti in this respect is notably low. The reason could hardly be found in endothermic chemical reactions. The accumulation of acid which is taking place during this time is presumably due to oxidation processes, which, while they may be only partial as compared with those that take place in ordinary plants, are nevertheless exothermic in their nature. A closer examination of this temperature relation would be of considerable interest.

Young fruits did not show the increased amount of acid that might be expected, though they do perhaps contain somewhat more acid than the ordinary tissues. It did not appear that the acidity varied to any noticeable extent in different parts of any one joint. A long, young joint showed at the base a similar acidity to that at the tip. Similarly, none of the mature joints that were tested showed any indication of inequalities in the longitudinal distribution of the acids. 9AM. M. 6PM. 9PM. ISm'U't.
