Applications of Potassium Silicate Decrease Black Spot Infection in Rosa hybrida `Meipelta' (Fuschia Meidiland™)

Effect of Absorbent Granules Coated by Potassium Permanganate on Postharvest Quality of Rose (Rosa hybrida) Cultivars

Enrichment of zeolite and sponge as ethylene absorbent with potassium permanganate was theidea of this study to provide an efficient way to scavenge ethylene during storage period ofthree Rosa hybrida cv. ‘Shiraz’, ‘Avalanche’, and ‘After-party’ cut flowers. A preliminaryexperiment revealed that two mL of potassium permanganate solution (1 mM) was enough toenrich two gra...

Histological analyses of the fungal endophytes in Rosa hybrida.

Endophytes are fungi that cause asymptomatic infections in leaves and stems of healthy plants. This study evaluated the presence of endophytic fungi on leaves of Rosa hybrida collected in Bogota, (Colombia) using histological techniques and light microscopy. Histological preparations showed fungal mycelium with few cells in the vascular tissue. Colonization of mesophyll cells was not observed. ...

Effect of Agar and Different Culture Media on the Micropropagation of Rosa hybrida cv.’Black Baccara’

In vitro propagation of plant has played a very important role in rapidmultiplication of cultivars with desirable traits and production of healthy and disease-free plants. In the present investigation, the objectives were to optimize the micropropagation of Rose hybrid ‘Black Baccarat’ cultivar. In proliferation step, the nodal segments (1.5 cm) was cultured on both liquid and solid media (MS, ...

The Biology and Ecology of Rosa x hybrida (Rose)

Nitrate and potassium uptake by greenhouse roses (Rosa hybrida) along successive flower-cut cycles: a model and its calibration

Rose (Rosa hybrida L.) plants grown for cut-flower production in greenhouses produce flowers in flushes year-round. Crop models for this system must handle the cyclical nature of productivity, which is determined by the horticultural production methods. Nutrition was not accounted for in previous rose growth models, since little is known about uptake of the essential nutrients by rose roots. Th...
