Genotypic variation of cut chrysanthemum response to high CO2 concentration: gr...

In this study sixteen cut chrysanthemum cultivars were used to evaluate the effects of high CO2 concentration (1500 μmol mol-1) on growth, time to flowering and visual quality as compared to the concentration used in commercial greenhouses (600 μmol mol-1). CO2 enrichment increased light use efficiency (11-41%) and total plant dry mass (TDM) (5-40%) in a cultivar dependent manner. This TDM increase was a result...

Melhoramento para elevada qualidade pós-colheita: validação do método de selecç...

Breeding for better keeping quality: validation of the selection method of promising genotypes. Water stress is one of the most important postharvest quality problems, resulting in shorter vase life and reduced consumer‟s satisfaction. This problem is enhanced in plants grown at high RH (RH > 85%) due to stomatal malfunctioning leading to shorter postharvest longevity. Previously, a subset of a segregating tetr...

Effect of relative air humidity on the stomatal functionality in fully develope...

Several studies have shown that stomata developed under long-term high relative air humidity (RH ≥85%) are malfunctional, resulting in a poor control of water loss. Yet, little is known about the dynamics of stomatal adaptation to moderate RH, and the possibilities to improve or reverse the destabilized stomatal responsiveness. In this study, a reciprocal transfer experiment was conducted in climate chambers us...

Qualidade pós-colheita de rosas: efeitos da humidade relativa e da variação gen...

Elevada humidade relativa (i.e. HR > 85%) durante a produção de rosas de corte reduz a sua longevidade em jarra, mas a magnitude desse efeito depende em larga medida da cultivar em causa. Na tentativa de compreender melhor os mecanismos ligados à sensibilidade a valores de HR elevada, foram analisadas folhas completamente desenvolvidas de quatro cultivares de rosas de corte: as tolerantes ‘Frisco’ e ‘Dream’, e ...
