“…European mistletoe ( Viscum album L.) is an evergreen perennial aerial hemiparasitic plant with a special mode of cellular respiration that parasitizes various tree species and is distributed in Europe, Africa, America, Australia, and Asia 1 , 2 . Mistletoe spreads actively in anthropogenic ecosystems and in some cases reaches 80% faster spreading than in natural ecosystems 3 , 4 . Thus, it creates a problem for green urban areas (reduces plants’ decorative effect and vitality), which cannot be solved without damaging the host plant and when lacking control technologies.…”

Viscum album L. (VA) is a unique plant with regard to its biological content. It is rich in many different metabolites with high potential in various spheres of human activity. We conducted a pilot study with 5 VA aqueous extracts of different host-tree species for pre-sowing treatment of Cucurbita maxima ‘Hokkaido orange’ seeds. We set the following objectives consisting of hypotheses (1) H01 is based on different effects of tested VA extracts depending on host trees and time of pre-treatment; (2) H02 focuses on the allopathic properties of the tested extracts affecting the plant growth and development by dose–response relationship; (3) A01 considers highly biologically active compounds of VA extracts also containing allelochemicals that can be used to regulate plant growth processes and create eco-friendly and resilient cities. The analysis of the stimulatory allelopathy index for 7 parameters demonstrates the direct effect of VA extracts in 62.3% of cases. The variability of the broad spectrum of effects of VA extracts of different host trees on the ontogenesis of C. maxima plants shows the presence of potential allelochemicals, resulting from the vital products of the host-parasite relationship. These effects are not fully explained by total polyphenol content and antioxidant activity as in previous studies of other mistletoe species. The authors consider this work a pilot study that expands the areas of application of VA extracts and knowledge about potential sources of allelochemicals.
