Winter structure and development of apple buds

Text from page 2: Practical orchard experience shows that much can be done to regulate the fruitfulness of trees. It is apparent, therefore, that if the fruit grower wishes to understand the factors and influences which favor or oppose fruitfulness, he must have a thorough know1edge of all the stimu1i affecting fruit bud formation end be so familiar with the general appearance of the buds and with their structures that he can observe and understand the responses to these stimuli end use them as a guide to intelligent orchard management.
