Tree canopy defoliation can reveal growth decline in mid-latitude temperate forests

open access: yesEcological Indicators, 2021
Climate and weather fluctuations and changes are the most important environmental drivers of tree canopy defoliation, an indicator of forest health. We examined the relationship between tree defoliation and Basal Area Increment (BAI), a dimension of tree

Health status of forest stands on permanent research plots in the Krkonoše Mts.

open access: yesJournal of Forest Science, 2010
Damage to beech, mixed (beech with spruce to spruce with beech) and spruce stands in the Krkonoše Mts. is described on the basis of evaluation of transition matrices describing the probability of a change in the assessment of defoliation of particular ...

An Experimental Comparison of Two Methods on Photosynthesis Driving Soil Respiration: Girdling and Defoliation.

open access: yesPLoS ONE, 2015
Previous studies with different experimental methods have demonstrated that photosynthesis significantly influences soil respiration (RS). To compare the experimental results of different methods, RS after girdling and defoliation was measured in five ...

Simulated impacts of insect defoliation on forest carbon dynamics

open access: yesEnvironmental Research Letters, 2012
Many temperate and boreal forests are subject to insect epidemics. In the eastern US, over 41 million meters squared of tree basal area are thought to be at risk of gypsy moth defoliation. However, the decadal-to-century scale implications of defoliation

Effects of Defoliation on Phenolic Concentrations, Antioxidant and Antibacterial Activity of Grape Skin Extracts of the Varieties Blaufränkisch and Merlot (Vitis vinifera L.)

open access: yesMolecules, 2019
Vitis vinifera L. has been highlighted by its many positive effects on human health, including antibacterial, anti-inflammatory and antioxidant activity due to its rich phytochemical content. Removing six basal leaves has great potential to influence the

Defoliation and nitrogen fertilization on the physiological quality of soybean seeds [PDF]

open access: yesRevista Ciência Agronômica, 2023
Stress caused by defoliation can compromise the physiological quality of soybean seeds. However, there is evidence that the application of nitrogen (N) can be an alternative to reduce the qualitative losses in seeds caused by defoliating insects.

Effects of time and intensity of defoliation on yield and yield components of corn

open access: yesپژوهشهای زراعی ایران, 2009
In order to evaluate the effects of time (20, 40, 60 and 100 days after sowing) and intensity of defoliation (0, 33, 66 and 100%) on a corn cultivar ( three way cross 647), a complete randomized block design with split plot arrangement and three ...

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.
