Growth and flowering of Helleborus argutifolius (Viviani) grown in pots depending on substrate type

Abstract

A b s t r a c tAn experiment was conducted on the effect of substrate type on growth of Corsican hellebore (Helleborus argutifolius Viviani). Plants were grown for two years in pots with substrates whose components included Klasmann highmoor peat and Hartmann highmoor peat, mineral soil, expanded clay and perlite at various volumetric ratios. Vegetative growth and flowering were observed in hellebores. It was shown that substrates exhibited a varied effect on plant growth. Corsican hellebore in a substrate with a considerable addition of mineral soil was lower, but more branched, and it did not form inflorescences. An optimal medium for growing H. argutifolius in pots was Hartmann's de-acidified peat + mineral soil (1:1 v:v). In this medium vegetative growth of plants was extensive, flowering was early and abundant, and long peduncles were produced.

The influence of substrate type and chlormequat on the growth and flowering of marigold (Tagetes L.)

“…According to Hou and Yang (2011) and Vujošević et al (2013), best quality marigold seedlings are produced when peat is the principal component of the growing media. The favourable impact of highmoor peat (together with mineral soil) has also been reported for the growing and flowering of the Corsican hellebore (Henschke et al 2014). Witcher (2008) described the highmoor peat-based substrate as a basic substrate component in the production of marigolds, and coconut fibre as its very promising substitute.…”
