Development of roots and shoots of certain deciduous tree seedlings in different forest sites

Arthur Everett Holch, University of Nebraska - Lincoln

Abstract

This investigation deals with the activities of 5 species of deciduous forest-tree seedlings. Each species was grown in 3 habitats, including the one in which it naturally occurs. The study includes the development of both roots and tops during the first 3 years; measurements of the factors of the environment; and the physiological responses of the plants in terms of transpiration, photosynthesis, and growth. From 1927 to 1929, this work was conducted in the oak-hickory forest fringing the Missouri River at Peru, in southeastern Nebraska.The great amount of labor involved in the excavation of the root systems of trees has been the principal deterrent in such investigations. In the study of the roots of mature trees, European workers have accomplished more than Americans. In America, however, initial root habit of trees has been more extensively studied.Nobbe experimented with the roots of conifers in Germany as early as 1875. He discovered striking differences in various species grown under similar conditions (cf. Jost, '07). During the 50 years following Nobbe's work, isolated investigations, especially in Germany and Russia, have laid the foundations for the studies of tree roots published since 1925. An ex- cellent resume of the work of European investigators is given by Büsgen and Münch (29).
