Stability of Ampelometric Characteristics of Vitis vinifera L. cv. 'Syrah' and 'Sauvignon blanc' Leaves: Impact of Within-vineyard Variability and Pruning Method/Bud Load [PDF]
, 2013 Historically, grapevine (Vitis vinifera L.) leaf characterisation has been a driving force in the identification of cultivars. In this study, ampelometric (foliometric) analysis was done on leaf samples collected from hand-pruned, mechanically pruned and

Quantifying leaf trait covariation and its controls across climates and biomes [PDF]
, 2018 Plant functional ecology requires the quantification of trait variation and its controls. Field measurements on 483 species at 48 sites across China were used to analyse variation in leaf traits, and assess their predictability.

Biologia Plantarum, 2011 Variation in photosynthetic parameters was observed between eight contrasting cacao (Theobroma cacao) genotypes. Net photosynthetic rate (PN) ranged from 3.4 to 5.7 μmol(CO2) m-2 s-1 for the genotypes IMC 47 and SCA 6, respectively.

Does initial spacing influence crown and hydraulic architecture of Eucalyptus marginata? [PDF]
, 2008 Long-term declines in rainfall in south-western Australia have resulted in increased interest in the hydraulic characteristics of jarrah (Eucalyptus marginata Donn ex Smith) forest established in the region's drinking water catchments on rehabilitated ...

Specific leaf area in barley: individual leaves versus whole plants [PDF]
New Phytologist, 1999 We have explored the relationships between specific leaf area calculated for a whole plant and its individual leaves. Barley was grown in hydroponics in controlled environment cabinets. Plants were harvested on the basis of physiological age (defined as the number of days after full expansion of leaves on the main stem) and the area and weight of whole,

Effect of light on the growth and photosynthesis of an invasive shrub in its native range [PDF]
, 2014 Invasive species' success may depend on ecophysiological attributes present in their native area or those derived from changes that took place in the invaded environment.

Specific leaf area predicts dryland litter decomposition via two mechanisms [PDF]
Journal of Ecology, 2017 Abstract Litter decomposition plays important roles in carbon and nutrient cycling. In dryland, both microbial decomposition and abiotic degradation (by UV light or other forces) drive variation in decomposition rates, but whether and how litter traits and position determine the balance between these processes is poorly understood.
