Excerpt from Gum Diseases of Citrus Trees in CaliforniaPrevious investigators had come to the conclusion that all gum diseases of citrus trees in California originated independently of micro-organisms.1 It was held that these diseases were largely auto genous in their nature, and frequently induced through the effects of certain climatic or soil conditions alone. It now appears evident that these environmental conditions cannot by themselves initiate the severe forms of gummosis in citrus earlier attributed to them, although certain factors are found to play (as they do in most para sitio diseases) an important role as contributing conditions which favor infection and invasion of the host by the causal parasites.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from The Relation of Rate of Maturity to Egg ProductionKennard also concluded from this experiment that the earlier maturing pullets attained greater body weight and laid relatively larger eggs.Such observations are suggestive even though the number of birds reported upon was not large, and they were not kept under com mercial conditions. It was decided, therefore, to undertake pullet segregation tests with large numbers of birds, in commercial ocks of Sonoma County, to determine the importance of rate of maturity as a factor in commercial ock management.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
