Two plants were placed in chambers subjected to equiv- alent diffuse illumination and humidity. The fruits similar to those. -i , FIG. 51.—Diagram illustrating the course of growth of a tomato during the six weeks of its development. The broken line is plotted from the average daily rate of growth during each week, and the solid line from the calculated in- creases in volume. i 1 . , FIG. 52.—Similar to fig. 51, but begin- ning at an earlier stage. The average daily rate is seen to form a graph which presents notable differences from the one plotted from variations in volume. measured in one showed thermometer readings of 19° to 21° C. and in the other 29° to 31° C. The daily rates of axial increase were as shown in table 124 for the weeks beginning on the given dates. The conditions under which both plants were grown were unfavor- able to development, but it is to be noted that the rates of increase.
