Increasing the light level in protected cultivation of ornamental crops via supplementary lighting is critical to enhance both production and external quality especially during periods low availability. Despite wide applications effects intensities were not previously addressed on water loss pathways. In this study rose plants cultivated at 100, 200 or 400 μmol/(m2.s) photosynthetic photon flux density (PPFD). The stomatal responsiveness desiccation, anatomical features cuticular...
In greenhouse horticulture, evaporative demand varies between seasons.For instance, plants are typically exposed to low relative air humidity (RH) during summer, whereas elevated RH prevails in winter.Since high cultivation impairs stomatal functioning, some opposite changes might be expected, when subjected long-term RH.To investigate this, Rosa hybrida 'Pasadena' was cultivated at 40, 60 or 90% RH.Plant performance, transpiration, closing ability and anatomy were recorded.As increased from...
Abstract Abiotic stress tolerance in plants is said to be induced by pre‐stress events (priming) during the vegetative phase. We aimed test whether drought priming could improve heat and wheat cultivars. Two cultivars “Gladius” “Paragon” were grown a fully controlled gravimetric platform subjected either no or two cycles tillering stage. At anthesis, both batches high temperature stress, kept as control. No alleviation of grain yield reduction due was observed. Higher CO 2 assimilation rates...
The important role of polyploidy in plant evolution is widely recognized. However, many questions remain to be explored address how affects the phenotype plant. To shed light on phenotypic and molecular impacts allopolyploidy, we investigated leaf development a synthesized allotetraploid (Cucumis × hytivus), with an emphasis chlorophyll development. Delayed maturation was identified C. hytivus, based delayed expansion, initial deficiency leaves disordered sink-source transition. Anatomical...
With the aim of improving shade tolerance cucumber, Cucumis ×hytivus, a newly synthesized allotetraploid, was obtained by crossing tolerant wild relative, C. hystrix, with cultivated sativus L. 'BejingJietou'. The results show that new ×hytivus only partly is an intermediate hybrid and it has not chlorophyll deficiency, which recovers during leaf development, but also lower carotenoid content. Three light conditions combination different intensities photoperiods were employed to investigate...
Abstract Climate change predictions foresee a combination of rising CO 2 , temperature and altered precipitation. Effects single climatic variables are well defined, but the importance combined genotypic effects is less known, although pivotal for assessing climate impacts, example, with crop growth models. This study provides developmental physiological data from factors two distinct wheat cultivars (Paragon Gladius), as basis to improve scenarios. The were grown in controlled chambers...
Ceratophyllum demersum (common hornwort) is presently considered the worst invasive submerged aquatic macrophyte in New Zealand. We explored global phylogeographic pattern of species, based on chloroplast and nuclear DNA, order to identify origin populations Zealand clarify if there were multiple introductions. The study identified geographically differentiated gene pools North America, tropical Asia, Australia, South Africa, likely native these regions, a recent dispersal event...
The effect of considering cultivar differences in stomatal conductance (gs) on relative air humidity (RH)-related energy demand was addressed. We conducted six experiments order to study the variation evapotranspiration (ETc) pot rose cultivars, investigate underlying processes and parameterise a gs-based ETc model. Several levels crop were realised by adjusting growth environment. commonly applied Ball–Woodrow–Berry gs-sub-model (BWB-model) models validated under greenhouse conditions,...
Two geographically distinct populations of the submerged aquatic macrophyte Ceratophyllum demersum L. were compared after acclimation to five different nitrogen concentrations (0.005, 0.02, 0.05, 0.1 and 0.2 mM N) in a common garden setup. The two an apparent invasive population from New Zealand (NZ) noninvasive Denmark (DK). with focus on both morphological physiological traits. NZ had higher relative growth rates (RGRs) photosynthesis (Pmax) (range: RGR, 0.06–0.08 per day; Pmax, 200–395...
Summary The importance of temperature responses photosynthesis and respiration in determining species distributions was compared two closely related freshwater macrophytes, C eratophyllum demersum . submersum differed significantly response to the short long term, despite being collected same geographical region, near A arhus, D enmark. distribution is narrower globally does not extend as far north , which a cosmopolitan species. Results from short‐term (within minutes) temperature‐response...
Plants' response to single environmental changes can be highly distinct from the multiple changes. The effects of a factor on wheat growth have been well documented. However, interactive influences factors different genotypes need further investigation. Here, treatments three important factors, namely water regime, temperature, and CO
