Comparison of the growth and development of dwarf rose cultivars propagated in vitro and in vivo by softwood cuttings

Shoot regeneration from stem and leaf explants of Dendranthema grandiflora Tzvelev (syn. Chrysanthemum morifolium Ramat.)

“…The observation that plants derived from adventitious shoots flowered earlier than those from nodal explants is probably due to the elevated hormone levels of the regeneration medium. Such minor differences, related to hormone carry-over effects have been reported for other plant species [21].…”

Micropropagation of Ficus benjamina clones

“…Large differences in in vitro proliferation rates among clones are reported in several plant species (Brandt 1990;Dubois et al 1988;Economou & Read 1986;Gertsson 1988). The aim of the present work was to compare the growth in vitro of different clones of F. benjamina.…”

Rosa spp. (Roses): In Vitro Culture, Micropropagation, and the Production of Secondary Products

“…Micropropagated plants are well suited for cut-flower production as they are more compact (Onesto et al 1985), branch better and sometimes yield more flowers (Reist 1985b). In addition, tissue culture-derived dwarf roses which are used for pot plant production have a faster rate of growth, flower earlier, and exhibit shorter shoots and more laterals than conventionally produced plants (Dubois et al 1988). Many of these differences favour micropropagation, but advantages are partly offset by higher production costs.…”

“…Present outlets include specialist rose growers and garden centres. As evidence of quality and acceptability of micropropagated roses, such as that provided by Dubois et al (1988), Martin et al (1981) and Reist (1985a,b), is assimilated by the horticultural industry, demand for micropropagated roses may increase rapidly. Micropropagation may be further enhanced by the transformation of roses by "shooty mutants" of Agrobacterium tume[aciens or by the root-inducing strains of Agrobacterium rhizogenes.…”
