Abstract

U ovom diplomskom radu provedena su istraživanja agronomskih svojstava na pet sorata
predivog lana. Pokus je postavljen na Pokušalištu Maksimir Sveučilišta u Zagrebu
Agronomskog fakulteta 2014. godine prema metodi slučajnog bloknog rasporeda u četiri
ponavljanja. U pokusu je bilo zastupljeno pet europskih sorata predivog lana (Viking, Viola,
Venica, Agatha i Electra). Nakon berbe lana, stabljike lana podvrgnute su biološkoj metodi
maceracije zagrijanom vodom u kontroliranim uvjetima različitim tvrdoćama vode (vrlo meka,
srednje tvrda i tvrda) u trajanju od tri dana pri 32C. Nakon močenja određen je prinos stabljike
nakon močenja, prinos vlakna, udio vlakna, prinos dugog vlakna i udio dugog vlakna. Na osnovi
provedene analize varijance utvrđena je signifikantna razlika za prinos stabljike nakon močenja
i prinos dugog vlakna. Najveći prinos stabljike nakon močenja imala je sorta Viola. Najveći
prinos ukupnog vlakna, prinos dugog vlakna te udio dugog vlakna ostvarila je sorta Electra.
Venica se pokazala najbolja za svojstvo udio ukupnog vlakna. Močenje mekanom vodom dalo
je najbolje rezultate za sva navedena istraživana agronomska svojstva.

Abstract (english)

In this thesis, agronomic traits were investigated on five varieties of fiber flax. The trial was set
up at the Maksimir Experiment Station of the University of Zagreb, Faculty of Agriculture, in
2014 according to the randomized complete block design in four replications. Five European
varieties of fiber flax (Viking, Viola, Venica, Agatha and Electra) were involved in the trial.
After harvesting the fiber flax, the flax stems were subjected to a biological method of
maceration with heated water under controlled conditions with different hardness of water (very
soft, medium hard and hard) for three days at 32°C. After retting, the dry stem yield after retting,
total fiber yield, share of total fiber, long fiber yield and share of long fibre were determined.
Based on the analysis of variance, a significant difference was found for the dry stem yield after
retting and the long fiber yield. The variety Viola had the highest dry stem yield after retting.
The highest yield of total fiber yield and long fiber and share of long fiber was achieved by the
variety Electra. Venica proved to be the best for the share of total fiber. Retting with soft water
gave the best results for all the investigated agronomic traits.
