Stomatal anatomy and closing ability is affected by supplementary light intensity in rose (Rosa hybrida L.)

A coupled model of photosynthesis, stomatal conductance and transpiration for a rose leaf (Rosa hybrida L.).

The following three models were combined to predict simultaneously photosynthesis, stomatal conductance, transpiration and leaf temperature of a rose leaf: the biochemical model of photosynthesis of Farquhar, von Caemmerer and Berry (1980, Planta 149: 78-90), the stomatal conductance model of Ball, Woodrow and Berry (In: Biggens J, ed. Progress in photosynthesis research. The Netherlands: Marti...

The Biology and Ecology of Rosa x hybrida (Rose)

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...

The Rose (Rosa hybrida) NAC Transcription Factor 3 Gene, RhNAC3, Involved in ABA Signaling Pathway Both in Rose and Arabidopsis

Plant transcription factors involved in stress responses are generally classified by their involvement in either the abscisic acid (ABA)-dependent or the ABA-independent regulatory pathways. A stress-associated NAC gene from rose (Rosa hybrida), RhNAC3, was previously found to increase dehydration tolerance in both rose and Arabidopsis. However, the regulatory mechanism involved in RhNAC3 actio...

RhVI1 is a membrane-anchored vacuolar invertase highly expressed in Rosa hybrida L. petals

Invertases are a widespread group of enzymes that catalyse the conversion of sucrose into fructose and glucose. Plants invertases and their substrates are essential factors that play an active role in primary metabolism and in cellular differentiation and by these activities they sustain development and growth. Being naturally present in multiple isoforms, invertases are known to be highly diff...
