Abstract

Investigated the potential regulation of adaptive characteristics of roses in complex use of biologically active substances and non-traditional organic fertilizers, which are represented by sewage sludge and ash of buckwheat husk. The work deals with change in the quantity and quality of the pigment complex, which is one of the possible ways of adaptation of plants. The influence of non-traditional fertilizers, which includes the necessary macro — and microelements and biologically active substances on the content of chlorophyll and carotenoids during flowering roses. It is shown that complex activities involving soil application of sewage sludge in the dose of 12 kg/m2, ash of buckwheat husk (100 g/m2), pruning the roots of the roses before planting by soaking in a solution of Mival-agro, 95 % ^stahlne powder (c.r.p.) within 12 hours and the subsequent dusting with ashes; during the growing season, watering twice Gumi (0.3 l/ha), spraying of Mival-agro, 95 % c.r.p. (10 g/ha) and the Bud (0.4 l/ha) contributed to the improvement of the quantitative and qualitative composition of the pigments in the leaves of the roses.

Keywords
