Abstract	Rana defolijacija kao ampelotehnički zahvat pokazuje pozitivne rezultate u podizanju kvalitete vina. Sorta 'Trnjak' autohtona je sorta Imotske krajine i Zapadne Hercegovine i zbog njene ugroženosti aktivno se radi na očuvanju sorte. Pokus je postavljen u svibnju 2019. godine, u vinogradu proizvođača Ivice Radalja. Postavljen je prema slučajnom bloknom rasporedu s dva tretmana, bazalnom defolijacijom nakon završetka cvatnje i kontrolom predstavljenom primjenom uobičajne ampelotehnike u pokusnom nasadu. Oba tretmana imala su tri ponavljanja s tri trsa. Rana defolijacija provedena je na način da su uklanjana četiri bazalna lista na svakoj mladici. Rezultati provedenih analiza pokazuju kako zahvat rane defolijacije nije značajno utjecao na mjerene parametre u uvometrijskoj analizi, mehaničkoj analizi, osnovnoj kemijskoj analizi i analizi organskih kiselina mošta. Što se tiče osnovne kemijske analize, rana defolijacija kod sorte 'Trnjak' pozitivno je utjecala na sadržaj šećera i pH vrijednost, a negativno na sadržaj ukupnih kiselina.
Abstract (english)	Early defoliation as an ampelotechnical procedure shows positive results in raising the quality of wine. The variety 'Trnjak' is an indigenous variety of the Imotska krajina and Zapadna Hercegovina and due to its endangerment, active work is being done on the preservation of the variety. The experiment was set up in May 2019, in the vineyard of Ivica Radalj. It was placed according to a random block schedule with two treatments, basal defoliation after flowering and control represented by the application of conventional ampelotechnics in the experimental vineyard. Both treatments had three repetitions with three vines. Early defoliation was performed by removing four basal leaves on each shoot. The results of the performed analysis show that the early defoliation did not significantly affect the measured parameters in uvometric analysis, mechanical analysis, basic chemical analysis and analysis of total organic acids. Regarding the basic chemical analysis, early defoliation in the variety 'Trnjak' had a positive effect on the sugar content and pH value, and negatively on the content of total acids.
