Scherer H.W. author Pacyna S. author Manthey N. author Schulz M. author text journal article 2006 In a pot experiment (culture substrate: perlite with a granulometric composition 0-3 mm) with peas (Pisum sativum L.) we studied the influence of sulphur supply on S and N concentrations, yield formation, symbiotic N₂ fixation and available amounts of glucose and sucrose. Under S deficiency conditions S and N concentrations as well as the amounts of glucose and sucrose in shoots and nodules were significantly reduced. We assume that the reduced amounts of available photosynthate with suboptimal S supply could become limiting to energy production and as carbon skeletons for ammonia assimilation, and therefore cause a lower N₂ fixation and a reduced yield formation. peas; sulphur supply; carbohydrates; symbiotic N2 fixation 10.17221/3348-PSE https://pse.agriculturejournals.cz/artkey/pse-200602-0004.php https://pse.agriculturejournals.cz/artkey/pse-200602-0004.php continuing 52 2 72 77 2006 12141178 periodical academic journal
