Abstract

Cilj ovog diplomskog rada je određivanje kvalitete ploda jabuke 'Braeburn' uzgajane ispod mreža protiv tuče. Koristile su se crvena i bijela mreža protiv tuče (Agritenax), dok kontrolna stabla nisu bila prekrivena mrežama. Mjerena je masa, kalo, boja i tvrdoća plodova te sadržaj topljive suhe tvari(TST) i sadržaj ukupnih kiselina (UK). Vrijednosti svojstava testiranih plodova jabuke obrađeni su analizom varijance i LSD testom uz razinu značajnosti P≤0,05 primjenom statističkog paketa SAS 9,4 (SAS institute, Cary, NC, USA). Nakon provedenih analiza, utvrđeno je da korištenje crvenih mreža ima veći utjecaj na kvalitetu plodova od bijele mreže protiv tuče, te da obje boje mreže imaju pozitivan učinak na kvalitetu plodova. Promjene u boji plodova se nisu pokazale signifikantnima. Ovim analizama se može zaključiti da mreže protiv tuče imaju široku namjenu u zaštiti i poboljšanju kvalitete plodova jabuke.

Abstract (english)

The task of this project was to determine the quality of apple fruit 'Braeburn' grown under the anti-hail network. Red and white (Agritenax) anti-hail nets were used, while the control trees were not covered with nets. Measurements were made of mass, color, and hardness of fruit, the content of the soluble substance (TST) and total acidity (UK). The values of properties of the tested apple fruits were analyzed by the variance analysis and the LSD test at the significance level P≤0,05 using the statistical package SAS 9,4 (SAS Institute, Cary, NC, USA). After the tests have been carried out, it has been found that the use of red nets has a greater impact on the quality of the fruits than the white netting, and that both colored nets have a positive effect on the quality of the fruits. Changes in the color of the fruit did not show any significance. This analysis suggests that anti-hail networks have a broad purpose in protecting and improving the quality of apple fruits.
