Arginīna fosfāta pielietošanas ietekme uz slāpekļa un oglekļa izotopu attiecību un elementu saturu skujkoku stādos
Аннотации
Darbā apkopota informācija par divām masspektrometrijas metodēm (ICP-MS un IRMS) un to pielietojumiem skujkoku pētījumos. Tika pētīti skujkoku – egles un priedes un augsnes substrāta paraugi. Priedes skuju paraugs iegūts no Latvijas parastās priedes (Pinus sylvestris), savukārt egles skuju paraugs no Latvijas parastās egles (Picea abies). Maģistra darba ietvaros tika analizēti gan elementi abos skujkoku paraugos, gan C un N izotopu attiecības, kā arī to masas daļas un iegūtie rezultāti salīdzināti savā starpā. Rezultāti tika izvērtēti un pētītas likumsakarības starp un iekš paraugiem. The paper summarizes the two methods of spectrometry (ICP-MS and IRMS) and their uses in coniferous studies. Samples of coniferous tree - spruce and pine and soil substrate were studied. The sample of pine needles was obtained from the Latvian pine (Pinus sylvestris), while the sample of spruce needles was obtained from the Latvian pine (Picea abies). Within the master’s work, the elements in both coniferous samples and the isotope relationships of C and N were analysed, as well as their mass shares and the results were compared with each other. The obtained results were evaluated and the regularities between and within the samples were studied.
