Genomic loci associated with leaf abscission contribute to machine picking and environmental adaptability in upland cotton (Gossypium hirsutum L.)

Journal of Advanced Research
Introduction: Defoliation by applying defoliants before machine picking is an important agricultural practice that enhances harvesting efficiency and leads to increased raw cotton purity.

Influence of meteorological conditions and crown defoliation on tree phenology in intensive forest monitoring plots in Slovenia

Acta Silvae et Ligni, 2014
Data from the forest monitoring programme in Slovenia were used to assess the relationship between tree phenology, crown defoliation and meteorological conditions in Fagus sylvatica, Quercus robur and Picea abies forests in the 2004-2013 period.

The Effect of Partial Defoliation on Growth Characteristics of Vitis vinifera L. cv. Cabernet Sauvignon I. Vegetative Growth

, 2017
The effect of partial defoliation over the whole canopy on the reproductive growth of Vitis vinifera L. cv. Cabernet Sauvignon was investigated. The 33% defoliation treatment prior to pea size and the 66% defoliation treatment prior to veraison adversely

Slowed Biogeochemical Cycling in Sub-arctic Birch Forest Linked to Reduced Mycorrhizal Growth and Community Change after a Defoliation Event

Ecosystems, 2016
Sub-arctic birch forests (Betula pubescens Ehrh. ssp. czerepanovii) periodically suffer large-scale defoliation events caused by the caterpillars of the geometrid moths Epirrita autumnata and Operophtera brumata.

Leaf‐chewing but not sap‐feeding herbivores create soil legacies that shape plant resistance through trait‐mediated, guild‐specific effects in Baccharis salicifolia

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Herbivory can affect the soil microbiome, creating legacies that affect plant resistance, but how these effects vary by feeding guild and the plant traits involved remain underexplored. We tested how soil legacies created by a leaf‐chewing caterpillar (Spodoptera exigua)

STUDY OF DEFOLIATION INTENSITY AND NITROGEN RATE EFFECTS ON YIELD, YIELD COMPONENTS AND GERMINATION TRAITS OF PRODUCED SEED IN WHEAT (Triticum aestivum)

Agricultura, 2013
A field experiment and a laboratory experiment were conducted in 2011-2012 to determine the effect of defoliation intensity and nitrogen rate on yield, yield components and seed germination of wheat (Triticum aestivum).

Distribution of 14C-photosynthetate in the shoot of vitis vinifera L. cv cabernet sauvignon II. the effect of partial defoliation

, 2017
The effect of partial defoliation of Vitis vinifera L. cv Cabernet Sauvignon on the distribution of photosynthetates, originating in leaves in different positions on the shoot at berry set, pea size, veraison and ripeness stages, was investigated ...

Plant–plant nitrogen transfer is prevalent in a semi‐arid shrubland and affects the foliar N content of recipient plants

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In agroecosystems, it is well known that nitrogen (N) can be transferred below‐ground among plants, especially between legumes and forage crops. However, we still lack a deep mechanistic understanding of this ecological process and its implications in plant communities,

Spatio-temporal modelling of forest monitoring data: modelling German tree defoliation data collected between 1989 and 2015 for trend estimation and survey grid examination using GAMMs

iForest - Biogeosciences and Forestry, 2019
Spatio-temporal modelling of tree defoliation data from the German forest condition survey is statistically challenging, particularly due to irregular grids. In the present study, generalized additive mixed models (GAMMs) were used to estimate the spatio-
