The climbing habit is an evolutionary key innovation in plants because it is associated with enhanced clade diversification. We tested whether patterns of species divergence and variation of three ecophysiological traits that are fundamental for plant adaptation to light environments (maximum photosynthetic rate [A(max)], dark respiration rate [R(d)], and specific leaf area [SLA]) are consisten...
BACKGROUND AND AIMS Nitrogen availability varies greatly over short time scales. This requires that a well-adapted plant modify its phenotype by an appropriate amount and at a certain speed in order to maximize growth and fitness. To determine how plastic ontogenetic changes in each trait interact and whether or not these changes are likely to maximize growth, ontogenetic changes in relative gr...
Interstocks improve the growth and salt resistance of lemon (Citrus limon (L.) Burm. f.) trees, but their effects on orange (Citrus sinensis (L.) Osbeck) trees are unknown. We grew 'Cleopatra' mandarin (CM) seedlings, budded trees of 'Salustiano' orange (SAO) on CM, 'Valencia Late' orange (VLO) on CM (VLO/CM), and interstock trees VLO/SAO/CM in pots of sand watered with nutrient solution contai...
Leaf trait data were compiled for 258 Australian plant species from several habitat types dominated by woody perennials. Specific leaf area (SLA), photosynthetic capacity, dark respiration rate and leaf nitrogen (N) and phosphorus (P) concentrations were positively correlated with one another and negatively correlated with average leaf lifespan. These trait relationships were consistent with pr...
Alternative methods for restoring tropical forests influence the ecological processes that shape recruitment of understory species. In turn, traits species recruited will provide now and over long term. We assess phylogenetic functional structure seedlings beneath monoculture plantations, mixed-species plantations (both active restoration) regenerating selectively logged native (passive restora...
High concentrations of airborne particulate matter (PM) in urban areas are great concern to human health. Urban greening has been shown be an effective and eco-friendly way alleviate particle pollution, attention its role mitigating pollution increased worldwide. The species-specific PM-capturing capacity ten urban-greening species Seoul was evaluated by leaf functional traits (average area (AL...
in this regard, the morphophysiologic and anatomic characteristics of six olive cultivars (nabali, feshomi, arbequin, zard, gordal and roghani) were investigated under drought. experiments were designed based on factorial and complete block random plot with two control treatments, -1.5 mpa stress and three replicates. the investigated factors were as follows: leaf area, specific leaf area, leaf...
With the aim to explore how plants acclimate elevation changes in understudied (sub)alpine tropics we tested two hypotheses along a 1000-m gradient Mexico: (H1) due severe increase abiotic constraints at higher elevations, functional traits of plant species will converge toward more resource conservation, and (H2) specific growth forms biogeographic origins present may influence interspecific t...
Failure to adjust the fertilization system quantitative needs, and especially dynamics of mineral demand, causes plant metabolism disorders, low utilization by plant, an increased risk environmental pollution. Additionally, unbalanced may reduce assimilation surface actively involved in photosynthesis, which determines yield potential individual varieties. The aim strict field experiment was de...
Drought is the major abiotic constraint affecting peanut productivity and quality worldwide. There is a pressing need to improve the water use efficiency (WUE) of rain-fed peanut production. Breeding varieties with higher water use efficiency is seen as providing part of the solution. The objectives of this work were to (i) evaluate genetic variation in WUE, harvest index, root dry weight, spec...
