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%.
Highlights
The active introduction of woody and shrubby plants into the composition of landscaping facilities and depositing carbon polygons requires the mobilization of a variety of technologies for replicating planting material, including rooting cuttings in vegetation structures [1, 2]
The purpose of the research is to evaluate the effectiveness of using a light-transforming shelter of vegetation structures consisting of a spunbond with a photoluminophore integrated into its structure when rooting physiologically active stem cuttings of Hungarian lilac
Light-transforming agrotextile was used as covering materials: polypropylene nonwoven spunbond 30 ± 3 g/m2, coated with polylactide varnish containing a new organic photoluminophore (PL) with different concentrations with absorption mainly in the 460560nm band, and re-emitting with a spectral maximum of 660 nm with a half-width of the spectrum of 610-730nm
Summary
The active introduction of woody and shrubby plants into the composition of landscaping facilities and depositing carbon polygons requires the mobilization of a variety of technologies for replicating planting material, including rooting cuttings in vegetation structures [1, 2]. The use of light-transforming and light-correcting films and plastics for these purposes makes it possible to regulate the spectral and other parameters of the luminous flux in quantitative and qualitative terms [4, 5]. The purpose of the research is to evaluate the effectiveness of using a light-transforming shelter of vegetation structures consisting of a spunbond with a photoluminophore integrated into its structure when rooting physiologically active stem cuttings of Hungarian lilac
