Defoliation Dynamics on Grazing Horizons in Pastures Intercropped by Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens

open access: yesTropical Animal Science Journal, 2020
The aim of this study was to quantify and verify the defoliation dynamics process of the Panicum maximum, Brachiaria brizantha, and Brachiaria decumbens intercropping during the formation of four grazing horizons in lenient grazing intensities and high ...

Screening for Fall Armyworm (Spodoptera frugiperda J. E. Smith) Resistance in Early‐Maturing Tropical Maize Adapted to Sub‐Saharan Africa

open access: yesPlant Breeding, EarlyView.
ABSTRACT Fall armyworm (FAW) (Spodoptera frugiperda J. E. Smith) has emerged as a serious pest since 2016 in Africa, affecting the food security and livelihoods of millions of smallholder farmers, especially those growing maize. Native genetic resistance to FAW is essential for reducing yield loss.

Intervalo e intensidade de desfolhação nas taxas de crescimento, senescência e desfolhação e no equilíbrio de gramíneas em associação Interval and intensity of defoliation on the growth, senescence and defoliation fluxes and equilibrium of associated grasses

open access: yesRevista Brasileira de Zootecnia, 2002
O experimento foi realizado no INRA (Institut National de la Recherche Agronomique) em Theix, França. Duas gramíneas (azevém perene e festuca)foram semeadas em caixas (0,13 m²) e submetidas a três intervalos (3,5, 7 e 14 dias) e três intensidades (160 ...

Leaf economics and tissue turnover dynamics in four perennial C4 grasses

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.
Abstract Warm‐season perennial grasses are important components of pasture systems in the United States, yet their functional characteristics and relationships with productive attributes remain poorly understood. This study evaluated tissue flow dynamics and leaf economic traits in four C4 forage grasses: eastern gamagrass (Tripsacum dactyloides (L.) L.

The effects of defoliation on plant community, root biomass and nutrient allocation and soil chemical properties on semi-arid steppes in northern China

open access: yes, 2012
Semi-arid steppes in northern China have severely deteriorated over the past 50 years, mostly due to improper grazing management. A defoliation experiment was conducted on a Leymus chinensis-dominated semi-arid steppe to provide guidelines of grazing ...

Defoliation Frequency and Intensity of Arrhenathherum elatius [PDF]

open access: yes
This experiment was conducted with the aim of studying whether the frequency and intensity of defoliation of the temperate grass fromental (Arrhenatherum elatius (L.) Presl.) affected its total dry matter (DM)/ha yield as well as the seasonal ...

Carbon allocation during defoliation: testing a defence-growth trade-off in balsam fir

open access: yesFrontiers in Plant Science, 2015
During repetitive defoliation events, carbon can become limiting for trees. To maintain growth and survival, the resources have to be shared more efficiently, which could result in a trade-off between the different physiological processes of a plant. The

Enhancing spring green‐up of warm‐season turfgrasses through late‐winter scalping

open access: yesCrop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Rapid spring green‐up of warm‐season turfgrasses in the transition zone is often desired to improve early‐season turfgrass quality, thereby increasing the acceptance of these species in arid and semi‐arid climates. This study evaluated the effects of late winter scalping on spring green‐up speed in 41 cultivars of bermudagrass (Cynodon spp ...

Defoliation of the vines before or after berry set: Physiological consequences and qualitative factors

open access: yesIVES Technical Reviews, 2019
Defoliation of the vines consists of eliminating the leaves in the grape bunch zone in a more or less intensive manner. It is a long-proven prophylactic technique that has seen a renewed interest in the current context of the reduction of phytosanitary ...
