Research notes: The influence of low temperatures on the development and structure of yield formation of three cold tolerant and a standard soybean variety

Abstract

<p>The amount and stability of the yield of soybeans cultivated under Swiss climatic conditions is still unsatisfactory. Breeding studies (Piattini, 1977; Soldati, 1976) in relation to yield structure under various climatic conditions in Switzerland were conducted. It became evident that poor utilization of the available yield potential of different soybean varieties could be attributed mainly to low temperatures in the course of the vegetation period.</p>
