Cytokinins in Rosa hybrida in relation to bud break

Physiologia Plantarum, 1997
To assess the role of endogenous cytokinins in growth and development of Rosa hybrida, their concentrations in bleeding sap and in roots, stem, leaves, axillary shoots and bottom breaks in three stages of development were quantified. Cytokinins were purified by means of immunoaffinity chromatography and HPLC, and identified by retention time, UV ...

Controlling the plant development of Rosa hybrida ‘Motrea’

Scientia Horticulturae, 1993
Abstract Influencing the development of rose plants after planting has been mainly focused on manipulation of the bottom-break formation. In this experiment, the plant development of Rosa hybrida cultivar ‘Motrea’ could be improved by certain plant treatments considering the diameter of the harvested shoots.

Rose (Rosa hybrida L.)

2006
Although rose transformation is successful, it remains difficult to transform myriad rose species as well as different rose genotypes. In this protocol, a detailed description of rose transformation is presented. This protocol relied on Agrobacterium-mediated transfer of embryogenic callus cultures.

Somatic Embryogenesis in Rosa hybrida

2018
Roses are among the most economically important cut flowers throughout the world. Improving a number of rose traits, including resistance to pests and diseases, flower color and form, vase life and fragrance are some of the major goals of rose breeding programs (Bao et al. in Plant cell, tissue and organ culture 109:411–418, 2012; Ludwig et al.

Response of selected antioxidants and pigments in tissues of Rosa hybrida and Fuchsia hybrida to supplemental UV‐A exposure

Physiologia Plantarum, 2003
The effect of supplemental UV‐A (320–400 nm) radiation on tissue absorption at 355 nm, levels of various antioxidants (ascorbate, glutathione, carotenoids and flavonoids) and of antioxidant scavenging capacity were investigated with leaves and petals of Rosa hybrida, cv.

Bilateral rooting and flower production inRosa hybridacuttings

The Journal of Horticultural Science and Biotechnology, 2008
The effect of cutting type (20 cm-long, three-to-four node cuttings, rooted at both ends and planted horizontally vs. vertical controls) on flowering was studied in the cut-rose cultivars 'Meidebenne', 'Meicofum' and 'Meitanet'. Rose plants were grown in rockwool cubes in a greenhouse for 9 months, with new shoots bent over to stimulate flowering ...

Embryo rescue in Rosa hybrida L.

Euphytica, 1993
Two crosses between Rosa hybrida L. cultivars, that fail to produce progenies by conventional means, were carried out. In one of them, total hip abscision occured seven weeks after pollination; in the other one, only 2% of the fertilized hips remained on the plants after eleven weeks. Four- and five-week-old fertilized ovules were isolated in the first

SOMATIC EMBRYOGENESIS AND SHOOT DEVELOPMENT IN ROSA HYBRIDA L.

Acta Horticulturae, 2010
This study was conducted to induce somatic embryogenesis in in vitro root and leaf explants of different Rosa hybrid cultivars. Somatic embryogenesis was induced at the ratio of 2.9~20.5% from in vitro roots of Rosa hybrida 'Charming', 'Sweet Yellow' (Korean cultivar), and 'Tineke' cultured in SH medium supplemented with 5 or 11 mg·L -1 2,4-D for 2 or

Rooting-enhancement of Rosa hybrida for tissue culture propagation

Scientia Horticulturae, 1982
Abstract The effect of combinations of auxin sources and concentrations, temperature shifts, light intensity and light reduction on shoot-tips were studied relative to root formation of Rosa hybrida L. ‘Bridal Pink’ propagated in vitro. 2,4-dichlorophenoxyacetic acid alone was almost ineffective, and similarly its combinations with other auxins were ...

Abscission of flower peduncles in rose (Rosa × hybrida) plants

Scientia Horticulturae, 1993
Abstract Abscission of flower buds was not observed when plants or harvested flowers of rose cultivars ‘Nubia’ and ‘Celica’, grown for cut flowers were kept for 3 weeks at 22°C in the dark. However, all young buds of the miniature rose cultivar ‘Orange Meillandina’ abscised after 6 days of darkness.
