Effects of the rootstock rosa canina var. laxa on the growth and development of five miniature rose cultivars

Abstract

Generally, in Republic Kosovo rose propagation by budding resulted in about 100-130 thousand seedlings during
a year. In Kosovo the most frequent rootstocks for roses are species Rosa canina’Laxa’. Miniature varieties of
roses (Rosa hybrida L.) are among the most important garden plants in our country.
The goal of this research was to study the level of compatability for some Miniature Roses, a same rootstock of
Rosa canina 'Laxa'.
Roses are conventionally propagated by cutting, budding, grafting and layering. Cutting and budding would be
the simplest way to increase the desirable rose varieties. Plant propagation by grafting is one of the oldest
horticultural practices and one that has intrigued the gardening and non-gardening public alike.
In this study there are included five miniature rose cultivars: ‘Zwergkönig’, ‘Roulettii’, ‘Bianco‘, ‘Fire Princess’,
‘Dresden Doll’. The experiment was conducted during 2010-2011, tested in a commercial farm in Prizren,
Kosovo. During the vegetation these parameters were measured: number and diameter of roots, length of flower
stems, diameter of structural shoots, number of flowers etc.
There was found a significant level of compatibility between rootstock with all tested cultivars.
