Sorting Cut Roses with Machine Vision
Transactions of the ASAE, 1994A machine vision system was developed to inspect cut roses and sort into quality categories similar to those used by human inspectors. Image processing techniques were developed to find the base of the stem, the top of the bud, visible portions of the stem, and the projected area of the bud. Quantitative features were identified to analyze rose quality,

Обосновано значение биоморфологического подхода в агротехнике черенкования. На примере двух сортовых групп роз рассмотрены факторы успешности зеленого черенкования. We note the need to use a biomorphological approach in the agricultural technology of cuttings ...

Dark fixation of CO2 by flowers of cut roses
Planta, 1976Complete flower heads of cut roses (cv. Baccara) were exposed to (14)CO2 for 1-4 h. The flower tissue was able to fix CO2 via PEP carboxylase (E.C. 4.1.1.31) in the dark; various TCA products were identified in petals, ovary and anthers, including malate, aspartate, citrate, serine/glycine, glutamate and asparagine. The concentrations of these labelled

Budded cuttings for propagating roses
Scientia Horticulturae, 1990A scion with a dormant bud and a leaf was budded onto a single internode of rootstock. After budding, the base of the rootstock was profitably treated for 30 s with an indole-3-butyric acid solution at 2000 mg l−1. The budded cuttings were rooted in a no. 3 perlite medium under a balance type mist system. Rooting of the budded cuttings was satisfactory

VASCULAR OCCLUSION IN CUT ROSE FLOWERS: A SURVEY
Acta Horticulturae, 1995The causes of low water uptake and water stress symptoms in cut rose flowers are briefly reviewed. Low water uptake is due to an occlusion, mainly located in the basal stem end. No evidence has been found for a reaction of the plant after cutting, in the formation of this occlusion.
