' I "*HE importance of seed origin in artificial reforesta-•tion has been recognized since the middle of the eighteenth century. Early research of European foresters was concerned largely with seed of Pinus stlvestrts and Picea. excelsa (5, 6, 11, 14, 17). More recent investigations were conducted by Langlet (7, 8, 9), who studied the morphological and physiological characteristics of seedlings and large trees produced from seed of different origin. In this country, the origin of seed received the attention of Pearson (12), Bates (4), Perry and Coover (13), Meuli and Shirley (10), Baldwin (3), and Rudolph (16). Both European and American studies dealt primarily with growth characteristics of different geographical strains induced largely by climatic conditions. The present study aimed to detect the differences in seed composition brought about by the state of soil fertility.
