How- ever, when there is only partial shading it is quite possible that the size of succulent fruits may be increased, and the time of ripening hastened, for the moisture and temperature factors under half-shade will play important roles. It has been found, for instance, that under cheese-cloth sev- eral varieties of strawberries bear a larger fruit; and that lettuce runs earlier to seed, (b) Indirect effect through the environment. —The practice of shading may modify the factors of the environment in a variety of ways; and each of these factors is impor- tant in the life relations of the plant. The purpose, of course, is primarily the modified light effect, yet frequently the effect on other factors is much more important. Aside from reducing the light, shading is important in the relations of the plant in order (1) To regulate hu- midity. (2) To conserve soil water. (3) To mitigate or equalize temper- ature. (4) To give partial protection from wind. (5) To maintain bet- ter physical con- dition of the soil. an actual reduction in the acid content. The acid- ity, however, is more marked in taste, and this be- cause of a marked reduction of sugar. The reduc- tion of the sugar content, as well as of certain other carbohydrates in fruits, seems to be general under such cultural conditions.
