The Role of Environmental Parameters in the Evolution of Holm Oak (Quercus ilex L. subsp. ballota (Desf.) Samp) Decline: Studies in the Iberian Peninsula

Forest Pathology, Volume 56, Issue 5, October 2026.
ABSTRACT The combination of geographical factors (climate, slope, orientation, lithology, water availability, etc.) and the pathogenicity of agents such as the oomycete from the kingdom Straminopile Phytophthora or Pythium species causes the plant disease known as oak decline in the Iberian Peninsula. Leaving aside the presence of the pathogen, the aim

Optimising Defoliation Frequency and Intensity to Enhance Forage Accumulation in Annual Ryegrass

Grass and Forage Science, Volume 81, Issue 4, October/December 2026.
ABSTRACT To increase grazing efficiency, it is necessary to understand morphogenetic responses and how they drive forage harvest. Our objective was to evaluate defoliation frequency (time between defoliations required for the expansion of 2, 3 and 4 leaves) and intensity (low: maintenance of 50% stubble height; intermediate: maintenance of 25% stubble ...

Defoliation patterns on a mixture pasture of forage sorghum and Alexandergrass

Semina: Ciências Agrárias
Detailing the morphogenic characteristics of tropical species that form mixed pastures allows a broader view of plant-animal interactions. The objective of this study was to evaluate the intensity and frequency of defoliation in a mixed pasture of ...

Influence of intensity of post-veraison defoliation or shoot trimming on vine physiology, yield components, berry and wine composition in Aglianico grapevines

, 2017
Background and Aims: Post-veraison trimming and defoliation have been proposed as strategies to decrease the concentration of berry carbohydrate at harvest and of wine alcohol, but it is unclear which of these two pruning techniques is more suitable and ...

Effect of defoliation intensity and timing on the growth of Populus alba and Salix babylonica x Salix alba

, 2019
Insect defoliations have detrimental impacts on timber production in commercial tree plantations. The effect of intensity and timing of defoliation on the growth of two commercial salicaceae was assessed at plantations located in the Delta of the Paraná ...

Tree-ring proxies of larch bud moth defoliation: latewood width and blue intensity are more precise than tree-ring width

, 2018
Reconstructions of defoliation by larch bud moth (LBM,Zeiraphera dinianaGn.) based on European larch (Larix deciduaMill.) treerings have unraveled outbreak patterns over exceptional temporal and spatial scales.

Effects of Light Intensity and Defoliation on the Receptiveness for Primary Induction in Festuca Pratensis Huds [PDF]

Seedlings of Festuca pratensis Huds. (cv. Salten) were raised at three different light intensities (141, 85 or 28 (mol m-2s-1 ) for 7 weeks after emergence and then either left uncut or defoliated 40 or 80% of total leaf area, before transfer to primary ...

Influence of frequency and intensity of defoliation on production and morphological development of Panicum maximum Jacq. cv. Sabi

, 1974
Severe defoliation (2cm height) at fortnightly intervals was extremely detrimental to foliage and root dry matter production. High intensity of defoliation appeared to be more detrimental than high frequency.
