Effects of defoliation intensity on soil food‐web properties in an experimental grassland community
Oikos, 2001We established a greenhouse experiment based on replicated mini‐ecosystems to evaluate the effects of defoliation intensity on soil food‐web properties in grasslands. Plant communities, composed of white clover ( Trifolium repens ), perennial ryegrass ( Lolium perenne

This article synthetizes observations from five experiments and reports on the effects of timing and intensity of defoliation on the white and red Vitis vinifera cultivars Pinot noir, Gamay, Merlot, Chasselas, and Doral. Intensive defoliation (removal of six basal leaves + six lateral shoots per shoot) was completed at three developmental stages of the

Habitat loss and alien tree invasion reduce defoliation intensity of an eruptive forest pest
Forest Ecology and Management, 2019Abstract In forest ecosystems, bush-cricket species often occur at low density for very long periods until they suddenly outbreak with important economic and ecological consequences. In the last decades, isolated but severe outbreaks were reported across Europe for several species belonging to the genus Barbitistes.

Effects of Corn Row Width and Defoliation Timing and Intensity on Canopy Light Interception
Crop Science, 2019ABSTRACTYield losses due to defoliation may be reduced in corn (Zea mays L.) grown at narrow compared to wider row widths. However, the physiological mechanisms behind this response are unclear. A 2‐yr experiment was conducted with two hybrids, row widths (38 and 76 cm), and a combination of defoliation timings–intensities: undefoliated control, V7–100%

Abstract Our ability to restore rangelands is limited, and it is unknown if seedling herbivory on its own, or in interaction with other stressors, is a major contributor to restoration failure. To address this, we conducted two experiments: a No Defoliation (ND) experiment (n = 48), in which seedlings from three perennial grasses (crested wheatgrass [

Abstract In an intensively managed commercial teak plantations wild undergrowth of two malvaceous weed species, namely, Pavonia odorata Willd. and Pavonia zeylanica (L.) Cav. Willd. trapped larvae of the teak defoliator, Hyblaea puera Cramer (Lepidoptera: Hyblaeidae) because of the presence of sticky trichomes all over the plant surface ...

Grassland Science
AbstractThe objective of this study was to evaluate the effects of different potassium (K) fertilization levels and defoliation intensities on performance of “BRS Zuri” guineagrass Megathyrsus maximus (Jacq.) B.K. Simon & S.W.L Jacobs (syn. Panicum maximum Jacq.). Treatments were the factorial arrangement of three K fertilization levels: 0 (control)

The response to Anthephora pubescens Nees to different intensities and frequencies of defoliation
African Journal of Range and Forage Science, 1975A factorial experiment with four frequencies (2, 4, 6 or 8-weekly) and five intensities (2, 5, 8, 11 and 14 cm height) of clipping was carried out on Anthephora pubescens in a pot soil culture. Response was measured in terms of total dry matter clipping yield, root production and top growth/root ratio.Keywords: responses|defoliation intensities ...
