Abstract

Abstract does not appear. First page follows.

The commercial method of propagating citrus in the United States consists of budding the desired variety onto a seedling rootstock. The principal commercial scion varieties in California are Eureka and Lisbon lemon (Citrus limonia Osbeck),3 Valencia and Washington Navel orange (Citrus sinensis Osbeck), and Marsh grapefruit (Citrus grandis Osbeck). The standard rootstocks are seedlings of sweet orange (Citrus sinensis Osbeck), sour orange (Citrus aurantium Linn.), grapefruit (Citrus grandis Osbeck) and to a limited extent rough lemon (Citrus limonia Osbeck). Since a budded citrus tree is a combination of either two species or two varieties of the same species, a study of the effect of the rootstock variety, or the effect of the presence of a bud union, must necessarily include a comparison of budded trees with unbudded trees, that is, with trees propagated by cuttings.

The writer’s investigation of cutting propagation has been undertaken primarily because of its bearing on the problem relating to stocks for citrus budding. However, this method may be useful also in commercial propagation of citrus, or in the production of plants for experimental physiological and pathological study.
