Page 10 - That a diminution of the supply of water accompanies the production of flowers in nature may be gathered from the fact that most trees and shrubs produce their flowers on short reduced shoots or spurs. The comparison of the anatomical structure of such a short shoot with that of a long leafy shoot confirms our statement, too, that an increase in stored food material is necessary for the production of flowers. The former shoots have far more storage tissue than the latter, the development...

That is he calls attention to the fact that all buds are not necessarily predestined to be a branch bud or a flower bud, but under certain conditions, more or less under the control of man, they may be changed from one form to the other. Regarding the methods by which this may be accomplished he says: "Plants will only develop flowering buds when the food material formed in the leaves is copiously stored up in the stem and branches as reserve material, and not when this material is immediately...

Page 53 - A marked decrease in the sap concentration of both bearing and non-bearing spurs occurs in late June or early July. Leaf sap from bearing and non-bearing spurs shows considerable variation in concentration. The number of fruits on a spur affects the concentration of neither spur nor leaf sap. Sugar and starch are present in slightly greater amounts in the bearing spur than in the non-bearing one.
