Variety traits
Rosa L.
Rose productivity is defined as the ability of a genotype to ensure the maximum yield of marketable products: the number of cut shoots in protected ground or the volume of essential oil accumulated in the inflorescences of essential oil varieties.
In the reference 256 varieties crop Rose, where this is mentioned in the description.
In commercial floriculture, productivity is measured by the number of marketable flowers per 1 m² per year, reaching 300–450 pieces in intensive greenhouse complexes. The assessment includes not only yield but also quality parameters of the cut flower, such as peduncle length, stem strength, and bud size.
For essential oil varieties, the key indicators of productivity are flower mass and the concentration of essential oil in inflorescences, where values at the level of 0,030–0,049% are considered promising. The realization of this potential directly depends on adherence to technological cultivation regulations.
