The effectiveness of agrotextile cover with organic photoluminophore in rooting cuttings of Hungarian lilac (Syringa josikaea J. Jacq. ex Rchb.)

Abstract

The effectiveness of the use of a light-transforming shelter of vegetation structures consisting of a polypropylene spunbond with an organic photoluminophore integrated into its structure during the rooting of physiologically active stem cuttings of Hungarian lilac was studied. The object of the study was reproductively mature Hungarian lilac plants located in the arboretum of the Nizhny Novgorod State Agricultural Academy with geographical coordinates 56°14'32.7” N 43°57'20.7”E. The unequal reaction of the tested samples of Hungarian lilac to the use of luminophore in the shelters of vegetation structures during the rooting of cuttings was established, which manifested itself in all characteristics of regeneration processes. High rates of callus formation were in the shelter variants with a higher concentration of luminophore: 73.16 ± 5.95% and 65.25± 4.80%. Lower than in other shelters, the result was recorded in the variant with the lowest luminophore density: 47.00 ± 3.62%.
