Ethephon and Silver Thiosulfate Affect Postharvest Characteristics of Rosa hybrida `Victory Parade'

Temperature and Postharvest Performance of Rose (Rosa hybrida L. ‘First Red’) and Gypsophila (Gypsophila paniculata L. ‘Bristol Fairy’) Flowers

The respiration of cut flowers of rose (Rosa hybrida L. ‘First Red’) and gypsophila (Gypsophila paniculata L. ‘Bristol Fairy’) increased exponentially with increasing respiration, with a Q10 value between 0 and 10°C of 3 for both flowers. The vase life of the flowers was negatively affected by simulated transport at higher temperatures whereas dry storage for 5 days at 0°C resulted in a vase li...

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...

Shading Impact on Qualitative Characteristics and Chlorophyll Content of Cut Rose (Rosa hybrida cv. Avalanche)

Light intensity is considered a limiting factor in greenhouse rose production. The main aim of this experiment was to evaluate the effect of shading treatments (0, 25, 50, and 65% shading) on quality and chlorophyll content of cut rose (Rosa hybrida cv. Avalanche), under greenhouse conditions. The experiment was planned in randomized completely block design with four replications. All shoots we...

The Biology and Ecology of Rosa x hybrida (Rose)

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. ...
