20.500.12556/RUL-135624 The effect of water supply on sweet cherry phytochemicals in bud, leaf and fruit The influence of a water supply on the content of phytochemicals (sugars, organic acids, hydroxycinnamic acids, flavonols, flavanols and anthocyanins) in the bud, leaf and fruit of sweet cherry (Prunus avium L.) was studied in two growing seasons. In addition, the shoot length, yield efficiency and fruit weight were determined. The trees of the cultivar ‘Regina’ on Weiroot 72 or Gisela 5 rootstocks were either irrigated or non-irrigated. Irrigated trees received, in addition to rainfall, an amount of water equal to 100% of evapotranspiration, while non-irrigated trees received only rainwater (40% less). An analysis of phytochemicals was performed using high-performance liquid chromatography combined with electrospray ionization mass spectrometry. Irrigated trees had a higher content of total sugars in leaf and bud, higher content of total organic acids in the fruit, and lower content of total hydroxycinnamic acids, total flavonols and flavanols in the leaf and fruit. Irrigated trees also had higher shoot length, fruit weight and lower yield efficiency. The content of phytochemicals in bud and leaf was not affected by rootstock, but the fruit phytochemical composition, shoot length and yield efficiency were. The content of phytochemicals in the bud and leaf was influenced by the presence or absence of fruits. Our results show that irrigation, rootstock and the presence of fruits had an influence on the composition of phytochemicals in sweet cherry. bud fruit irrigation leaf organic acids phenolics Prunus avium sugars češnja Prunus avium podlage sorte kemična sestava namakanje organske kisline sladkorji fenoli true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-22 12:58:09 2022-03-22 12:58:10 2022-09-14 04:14:19 0000-00-00 00:00:00 2021 0 0 11 str. iss. 6, art. 1131 Vol. 10 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.1/.7 2223-7747 10.3390/plants10061131 65632003 RAZ_Vosnjak_Matej_2021.pdf RAZ_Vosnjak_Matej_2021.pdf 1 94A239A40E5EDC6AB29B331C25D4161F dea924e56ea858743f37df7c558e18bbed71e6a6bee30f31a7921fd15e97910f e358e80b-a9d7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154815 https://www.mdpi.com/2223-7747/10/6/1131 1 57afb1a0-a9d7-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154814 Biotehniška fakulteta 0 0 0
