Wpływ światła na syntezę alkaloidów w łubinie wąskolistnym (Lupinus angustifolius). I. Akumulacja alkaloidów [Influence of light on the alkaloids synthesis in Lupinus angustifolius. I. Alkaloids accumulation]

It was established that the time of irradiation as well as the intensity of light have a fundamental effect on the synthesis and accumulation of alkaloids in Lupinus angustifolius plants. The increase of time and intensity of irradiation caused the increase of the percentage of alkaloids in plants up to some maximum. A further increase of illumination caused the decrease of the percentage of alkaloids. This regularity also concerns the ester fraction of alkaloids in Lupinus angustifolius.
