Studies on the influence of different nitrogen forms on the chemical composition of various cultivars of Lupinus albus L

The effect of nitrogen (N) forms on the chemical composition of three cultivars of Lupinus albus L. has been studied. The N form had a significant effect on accumulation of alkaloids, polyamines, and sugars dependent upon the cultivar. In general, the ammonium and nitrate (NH4++NO3-) and amine (-NH2) forms in all cultivars caused visible increases in alkaloid content. In the case of cv. 'Butan,' the (NH4++NO3-) and (NO3-) forms caused significant increases in polyamine contents, whereas Bradyrhizobium lupini plus (NH4++NO3-), N deficiency (Nd), and (NH4+) forms caused a decrease of polyamine levels. The N forms did not influence polyamine contents as much in cvs. 'Marta' and 'Multolupa.' The Bradyrhizobium lupini plus (NH4++NO3-), (NO3-), (NH4+), (NH4++NO3-), and (-NH2) caused a decrease of total sugars in seeds of 'Butan' and 'Marta' cvs. © Taylor & Francis Group, LLC.
