Dependence of fiber properties on the properties of the flax plant

Abstract

The research results of phenological (early flowering and yellow ripening), morphological (plant height, technical stem length and stem thickness) and textile-technological properties (fiber length, fineness and strength) of five flax cultivars having differently long vegetation periods and cultivated with additon of different amounts of nitrogen (0, 30, 60 and 90 kg/ha) are presented. Fiber flax trials were conducted during one year in the lowland continental part of Croatia in Zagreb in eutric cambisol and in Križevci in stangosol albic using the method of randomized block arrangement with four replications (repetitions). On the basis of morphological research and textile-technological properties of fiber flax it was found that there are significant differences between the investigated cultivars and the applied nitrogen quantities. According to the results of studied traits it is not necessary to add more than 30 kg /ha of nitrogen in fiber flax fertilization. Conducted correlation analyses showed that there is an influence of nitrogen on the properties of flax fiber and that there is a dependence of fiber properties on the properties of the flax plant.
