Researches on plant respiration IV— The relation between the respiration in air and in nitrogen of certain seeds during germination, (b) seeds in which carbohydrates constitute the chief food reserve

Part III of this series (Leach and Dent, 1934) dealt with experimental data concerning the effect on the respiration rates and respiratory quotients of certain fat-storing germinating seeds when successively surrounded by atmospheres of air, nitrogen, and air. The present paper describes similar data relating to the respiration of germinating seeds in which the predominant food reserves are carbohydrates. The seeds used in the present investigation, as with those used in the previous one, were of species belonging to genera widely separated from one another phyletically. The seeds were all obtained from Messrs.Sutton & Sons of Reading and the species and varieties used were as.
