Transport of Nitrogen in the Plant

Abstract

THE general question of translocation in plants demands attention, not only because of its practical importance in horticulture, but perhaps even more so because of its intensely controversial nature. Recent work on the translocation of carbohydrates in the cotton plant, by T. G. Mason and E. J. Maskell, has already been reviewed in NATURE (123, pp. 133–135; 1929). Maskell and Mason have extended their work to the translocation of nitrogen. This work, which appears as Memoir 2, Series B (1930), from the Cotton Research Station, Trinidad, is as valuable a contribution to the literature of nitrogen metabolism as to that of translocation.
