Propagation of Dog Roses (Rosa Canina L.) by Seed

Dormancy and germination in Rosa multibracteata Hemsl. & E. H. Wilson

“…However, in R. multibracteata, germination did not exceed 5% in any of the treatments without cold stratification except the one in which the testa had been fully removed. The effects of GA 3 on dormancy vary among different rose species (Xu et al, 1993;Liu et al, 2001;Tillberg, 1983;Hoş afçı et al, 2005). In the present study, neither GA 3 nor smoke water improved germination even when combined with mechanical scarification or cold stratification.…”

Improved technique for treating seed dormancy to enhance germination in Rosa × hybrida

“…Germination of rose achene is a bit of a challenging task due to the presence of endogenous and exogenous dormancy ( Baskin & Baskin, 1998;Hoşafaçı et al, 2005;Alp et al, 2008;Werlemark, 2009). Proper storage conditions and any treatment given to the achene to regulate the physiological and morphological conditions of seeds are important to consider.…”

“…Even high concentrations of abscisic acid (ABA) are present in the pericarp and testa of rose seed, which may block germination (Bo et al, 1995). The germination of seeds in the genus Rosa is not easy due to the presence of endogenous and exogenous dormancy (Baskin & Baskin, 1998;Hoşafaçı et al, 2005;Alp et al, 2008;Werlemark et al, 2009). De Vries and Dubois (1987) and Gudin et al (1990) revealed that limited germination of rose achenes, due to pericarp and endocarp thickness, can be controlled by factors such as temperature during maturation of achenes and genetic factors.…”

Enhancing Seed Germination in Rose (Rosa rubiginosa L.)

“…Therefore seed propagation can be the easiest method for these species [4]. However, seed propagation is difficult because of the low germination percentage, a result of prolonged seed dormancy [5][6][7][8].…”
