The influence of stages of maturity on the agronomic traits of fibre flax introduced varieties

Abstract

The harvest time of fibre flax is influenced by climatic conditions, varieties, stages of maturity and the crop's final use. In addition, the time of harvesting of fibre flax affects the quality of the fibres. Fibre flax can be harvested in few stages of maturity. So, this paper presents the influence of three stages of maturity (green, yellow and full ripening) on the agronomic traits (stem yield, stem yield after retting, total fibre yield, share of total fibre, long fibre yield, share of long fibre) of five fibre flax varieties. Varieties trials with fibre flax were set up in two years (2010-2011) and in two locations: at the experimental fields of the Faculty of Agriculture in Zagreb on eutric cambisol and of the College of Agriculture at Križevci on pseudogley on level terrain. The trials were carried out according to the randomized complete block design (RCBD) with four replications. According to the results of the two-years research into the agronomic traits of fibre flax, significant differences were established among the varieties and among the stages of maturity under study. The varieties Agatha, Viola and Electra recorded higher values of investigated traits. All varieties achieved higher values of investigated traits at Križevci (production on heavier soil in which some of winter moisture remained available in spring months). The highest values of investigated traits were recorded when the fibre flax were harvested in the green ripening.

Morphological characteristic of fiber flax seedlings regard to different pH water solution and temperature

“…Fibre flax have the main yield fibre, whereas linseed (oilseed flax) have seeds as the primary yield and straw is the secondary yield. As morphological differences, the fibre flax is 80-150 cm tall and poorly branched, while linseed is 45-80 cm tall and more branched (Couture et al, 2002;Pospišil, 2013;Butorac et al, 2017;Butorac et al, 2018).…”

Effect of Nitrogen on the Properties of Flax (Linum usitatissimum L.) Plants and Fibres

“…For more than 20 years, there has been cooperation between agronomists and textile-oriented specialists with the aim of revitalizing the sustainable and ecological production of flax fibres in Croatia. Since Croatia does not have its own cultivars [ 5 , 6 ], it is necessary to introduce cultivars from Europe, which are grown in climatic conditions similar to Croatian cultivars [ 7 , 8 , 9 , 10 , 11 , 12 ]. Therefore, it may be assumed that the newly formed climate conditions would cause the reduction in the valuable properties of flax plant and fibres.…”

“…Considering the obtained results, the investigation continued, and the influence of nitrogen fertilization on the agronomic properties (dry stem yield, dry stem yield after retting, total fibre yield, share of total fibre, long fibre yield and share of long fibre) of fibre flax cultivars was investigated [ 11 ]. Based on the analysis of the results, it was concluded that the cultivars, Agatha, Viola and Electra, recorded the highest values for the investigated properties (dry stem yield, dry stem yield after retting, total fibre yield, long fibre yield) over three years and the highest share of total fibres and long fibres over one or two years.…”
