20.500.12556/RUL-135513 Influence of nitrogen, calcium and nano-fertilizer on strawberry (Fragaria × ananassa Duch.) fruit inner and outer quality The production system, especially fertilisation has an important effect on yield and quality of strawberries. In the present study, plants were fertilized with different doses of nitrogen (0–100% recommended doses), calcium chelate, as well as nano fertilizer Lithovit. Strawberry cultivar ‘Clery’ yield and quality parameters (fruit color and firmness) including nutritional indicators (total soluble solids, sugars, organic acids, phenolic and volatile compounds) were monitored. Volatiles were identified and monitored using headspace solid phase microextraction and analysed using gas chromatograph-mass spectrometry (SPME/GC-MS) and sugars, organic acids, and phenolic compounds with high performance liquid chromatography. Organic acids and phenolic compounds were detected with mass spectrometer (HPLC/MS). Both nitrogen and calcium fertilisation had altered sugars, organic acids, volatile and phenolic contents in strawberry fruits. Fertilisation with higher doses of nitrogen and calcium increased the content of unpleasant aromas aldehydes hexanal (up to 3.8-fold) and (E)-2-hexen-1- (up to 3.7-fold). The content of fruity esters was uppermost in fruits fertilised with nano-fertiliser Lithovit (up to 2.3-fold). Fertilisation with N and Ca decreased the strength of ketone and terpenoids fruity aroma. The highest content of total phenols, as well as all individual hydroxycinnamic and hydroxybenzoic acid derivatives were obtained in the nanofertiliser Lithovit treatment. Fertilisation, especially with nitrogen, had mostly negative impact on strawberry flavour while nano-fertilization with Lithovit improved strawberry phenolic content and aroma. strawberries fertilisation nitrogen calcium lithovit volatiles phenolics jagode gnojenje dušik kalcij hlapne snovi fenoli true false true Angleški jezik Slovenski jezik Članek v reviji 2022-03-17 08:50:23 2022-03-17 08:50:24 2022-09-14 04:13:45 0000-00-00 00:00:00 2021 0 0 18 str. iss. 5, art. 997 Vol. 11 May 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.75 2073-4395 10.3390/agronomy11050997 63686147 RAZ_Cvelbar_Weber_Nika_2021.pdf RAZ_Cvelbar_Weber_Nika_2021.pdf 1 4AD896F12C0E56EA4FD9F0ABB39F8645 97f1c0dd5f99c53715751f45497e8990ec7ad12d0afc15e361060a451cf350bf 4432cbd8-a5c7-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154625 https://www.mdpi.com/2073-4395/11/5/997 1 e5d7ae82-a5c6-11ec-8556-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=154624 Biotehniška fakulteta 0 0 0
