| dc.description.abstract | Literatūras apskatā ir aprakstīts augu ķīmiskais sastāvs un gaismas ietekme uz to. Apkopotas paraugu sagatavošanas un analīzes metodes. Darbā ir veikta četru dažādu ģiņšu mikrozaļumu diedzēšana pie 4, 8 un 12 stundu ilgiem fotoperiodiem. Spektrometriski ir noteikta kopējā hlorofila un karotenoīdu koncentrācija, kopējā polifenolu koncentrācija un antiradikālā aktivitāte augos. Noteica mikroelementu un makroelementu sastāvu augos ar ICP-MS metodi. Noteica brīvo aminoskābju koncentrāciju augos ar HPLC-MS metodi. Iegūtie dati salīdzināti savā starpā, kā arī tika salīdzināts ķīmiskais sastāvs atkarībā no fotoperioda. | |
| dc.description.abstract | The literature review describes the chemical composition of plants and the effect of light on it. Four different species of microgreen were cultivated at 4, 8 and 12 hours long photoperiods. Methods of sample preparation and analysis were compiled. The total chlorophyll, total carotenoid concentrations, total polyphenol concentration and antiradical activity in plants were determined spectrometrically. The composition of microelements and macroelements in plants was determined by ICP-MS method. The concentration of free amino acids in plants was determined by HPLC-MS method. The obtained data were compared with each other, as well as the chemical composition was compared depending on the photoperiod. | |
