Leaf Traits of Trees in Tropical Dry Evergreen Forests of Peninsular India

open access: yesEcologies, 2021
A plant functional trait study was conducted to know the existing relationship between important leaf traits namely, specific leaf area (SLA), leaf dry matter content (LDMC), and leaf life span (LL) in tropical dry evergreen forest (TDEFs) of Peninsular ...

Evaluation of Argentine wild sunflower biotypes for drought stress during reproductive stage [PDF]

open access: yes, 2012
As in several regions where sunflower production has moved to areas with limiting water availability, the search for water-stress tolerant genotypes has been intensified. Helianthus annuus ssp. annuus L.

Regional‐Scale Relationships of Leaf Area Index to Specific Leaf Area and Leaf Nitrogen Content

open access: yesEcological Applications, 1994
Specific leaf area (SLA) is an important link between vegetation water and carbon cycles because it describes the allocation of leaf biomass per unit of leaf area. Several studies in many vegetation types have shown that canopy SLA is closely related to canopy leaf nitrogen (N) content and photosynthetic capacity.

Seasonal Variation in Leaf Growth and Antioxidant Content of Moringa oleifera Cultivated at Buenos Aires, Argentina [PDF]

open access: yes, 2016
The properties and applications of Moringa oleifera are so vast that it is called the "miracle tree". The objective of this work is to study the seasonal variations in the leaf antioxidant content and the scavenging activity on DPPH radicals in ...

A Prototype Sensor for Estimating Light Interception by Plants in a Greenhouse [PDF]

open access: yes, 2008
Light interception is one of the most important factors for plant growth. The intercepted amount depends on the incoming radiation in the greenhouse and the percentage of interception by the crop and is directly related to the leaf area.

Tree mortality across biomes is promoted by drought intensity, lower wood density and higher specific leaf area.

open access: yesEcology Letters, 2017
Drought events are increasing globally, and reports of consequent forest mortality are widespread. However, due to a lack of a quantitative global synthesis, it is still not clear whether drought-induced mortality rates differ among global biomes and ...

Effect of expansion time and sunlight radiation on the functional and anatomical traits of mango tree leaves

open access: yesRevista Agrogeoambiental, 2018
The mango tree (Mangifera indica L.) is cultivated on a large scale in Brazil for economic purposes. Since the leaves, as the main photosynthetic organs, play an essential role in fruit production, the primary objective of the present study was to ...

Foliar and wood traits covary along a vertical gradient within the crown of long-lived light-demanding species of the Congo Basin semi-deciduous forest [PDF]

open access: yes, 2019
Plant functional traits have shown to be relevant predictors of forest functional responses to climate change. However, the trait-based approach to study plant performances and ecological strategies has mostly been focused on trait comparisons at the ...

Effect of shade on the leaflet morphology of wild Pistachio sapling under drought stress [PDF]

open access: yesمجله جنگل ایران, 2019
In this research, the effects of drought stress and shade on leaflet morphology of wild pistachio (Pistacia atlantica subsp. Mutica) saplings were evaluated in Albroz Research center (Karaj, Iran) in the summer of 2014.

Above- and below-ground competition in high and low irradiance: tree seedling responses to a competing liana Byttneria grandifolia [PDF]

open access: yes, 2008
: In tropical forests, trees compete not only with other trees, but also with lianas, which may limit tree growth and regeneration. Liana effects may depend on the availability of above- and below-ground resources and differ between tree species.
