Assessment of Biometric Parameters and Health of Canna’s Cultivars as Plant Useful in Phytoremediation of Degraded Agrocenoses

Recently, the ecological awareness of society and need to take care our surroundings natural environment has significantly increased. There is also an urgent problem searching for new, environmentally friendly techniques its purification (soil, ground surface waters, sewage sludge air) with use living organisms, especially higher plants. One plant species investigated phytoremediation canna. Ten varieties canna, grown on degraded garden soil, were tested in this respect. The disease index composition fungi inhabiting organs, growth dynamics, parameters photosynthesis gas exchange determined. conducted research showed that cannas are able satisfactorily grow even seemingly unfavorable soil conditions strong degradation. Among a total 24 obtained from genus Fusarium, considered as pathogenic Alternaria alternata, and, less frequently, Thanatephorus cucumeris Botrytis cinerea, dominated. cultivars ‘Picasso’, ‘Cherry Red’, ‘President’ ‘La Boheme’ had lower rates than least affected ‘Botanica’, ‘Wyoming’, ‘Robert Kemp’ ‘Lucifer’ cultivars. Those turned out be most beneficial they can recommended cultivation strongly degenerated soils.
