Defoliation Frequency and Intensity of Arrhenathherum elatius [PDF]

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 ...

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

, 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 ...

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

Revista 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 ...

Spodoptera litura (Lepidoptera: Noctuidae) Adult Abundance and Larval Host Plant Use in the Ord River Irrigation Area, Western Australia

Austral Entomology, Volume 65, Issue 4, November 2026.
ABSTRACT Spodoptera litura (Fabricius) is a highly polyphagous lepidopteran pest; however, little is known about its seasonal population dynamics or larval host plant use in northern Australia. Improved understanding of the ecology of S. litura is increasingly important given the anticipated expansion of Bacillus thuringiensis (Bt) cotton production in

Simulated beetle defoliation on willow genotypes in mixture and monotype plantations

, 2006
The effect of simulated beetle damage (0%, 25%, 50% and 75% mechanical defoliation) on 12 willow genotypes, grown in short-rotation coppice, was studied in a modified criss-cross experimental design.

Lotus tenuis in Association with Arbuscular Mycorrhizal Fungi Is More Tolerant to Partial Submergence than to High-Intensity Defoliation

International Journal of Plant Biology
This study aimed to investigate the effect of the association of Lotus tenuis with arbuscular mycorrhizal fungi (AMF) on its development under high defoliation intensity or partial submergence in a P-deficient soil of the Salado River Basin in a pot ...

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

Frontiers 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

Evaluating seedling traits, maintenance and effective costs to support tropical forest restoration practices

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
Seedling weeding in tropical forest restoration may not be universally needed across all species. Its cost may not be affordable for private landowners. This research shows that all landowners who wish to plant trees on their lands should be encouraged to do so—weeding or no weeding.

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.

Effect of defoliation interval and height on the growth and quality of Arachis pintoi cv. Amarillo [PDF]

, 2007
The effect of defoliation on Amarillo (Arachis pintoi cv. Amarillo) was studied in a glasshouse and in mixed swards with 2 tropical grasses. In the glasshouse, Amarillo plants grown in pots were subjected to a 30/20°C or 25/15°C temperature regime and to
