Diagnostic significance of the synthesis of phenolic compounds and proline in the leaves of Schisandra chinensis and Actinidia arguta for the indication of the stress levels of plants under conditions of mixed plantings

The peculiarities of the accumulation polyphenolic compounds and free proline were investigated in leaves Actinidia arguta Shisandra chinensis during their cultivation vegetation containers with different ratios number plants, namely 1 : 1, 2 2. Monocultural (single-species) planting was used as a control. content plant carried out according to method, which is based on interaction ninhydrin reagent, forming pink-red color. amount determined by Folin-Ciocalteu method. It found that ratio plants grown together significantly affects primary secondary metabolites leaves. Under conditions mixed planting, more phenolic substances are accumulated compared monoculture. maximum content, 19.44 ± 0.91 mg/g dry weight (DW), observed A. experiment combination prevailing schisandra at S. 2:1. In same combination, actinidia contained highest (36.87 2.22 DW). studied root exudates experimental had an allelopathic inhibitory effect test culture. caused 12.0 % average decrease growth objects, 30.0 objects This allows us conclude about high activity schisandra’s allelochemicals, negatively affect development plants. optimal when since higher concentration container stress expressed increased phenols prolines its result comparative analysis can be assess mutual influence plantings optimize growing conditions, confirms diagnostic significance these for indicating state
