The objective of our studies were seeds of two lupin species Lupinus luteus L. and Lupinus angustifolius L. cvs. Lord and Graf respectively. Lupin seeds were germinated at 15 and 24°C and during two, three and four days. In the lupin sprouts antinutritional factors: alkaloids and raffinose family oligosaccharides (RFOs) and five nitrogen fractions: non protein (Nnp), albumin (A), globulin (G), glutelin...
The influence of different nitrogen forms: (N2), [N2+(NH4++NO3-)], (NH4+), (NO3-), (NH4++NO3-) and (-NH2) on changes of albumin, globulin, prolamin-glutelin, non-fractioned nitrogen and non-protein nitrogen fractions of the protein seed of alkaloid-low content Lupinus albus L. cv. Butan has been studied. The experiments were performed in a greenhouse on perlite using in all cases the constant P, K,...
The influence of an Uncaria tomentosa extract on the development of Capsicum plants grown in green-house conditions was examined. The effect of the treatment was investigated with microscopic techniques (light and electron microscope) in leaves from three levels of control plants and plants after treatment with the extract added to the soil in doses of 0.4 and 16 mg/ml (200 ml per pot/plant). In control...
Ten to 16 ethanol-soluble carbohydrate components were identified in the seeds of six Mexican wild lupins. The analysed carbohydrates included: monosaccharides, disaccharides, cyclitols, galactosyl cyclitols and raffinose family oligosaccharides. Stachyose and sucrose were the main carbohydrate component in the Lupinus montanus, L. rotundiflorus, L. exaltatus, L. mexicanus and L. elegans seeds. Only...
