Defoliation percentage in two soybean cultivars at different growth stages

Revista Brasileira de Engenharia Agrícola e Ambiental, 2015
The objective of this study was to evaluate the agronomic variables due to the effects of different levels of defoliation in the phenological phases of two soybean cultivars. The experiment was conducted during the 2011/2012 season, in a randomized block

Recent plant photosynthate as a driver of ecological and evolutionary processes

New Phytologist, EarlyView.
Timeline of key eco‐evolutionary outcomes arising from belowground allocation of recent plant photosynthate from shoots. Summary Plants rapidly allocate carbon from photosynthesis belowground via root exudates and root‐associated microorganisms. Here we synthesise recent evidence of our understanding of the consequences of this ‘fast’ pathway of recent

Effects of Invasive Winter Moth Defoliation on Tree Radial Growth in Eastern Massachusetts, USA

Insects, 2014
Winter moth, Operophtera brumata L. (Lepidoptera: Geometridae), has been defoliating hardwood trees in eastern Massachusetts since the 1990s. Native to Europe, winter moth has also been detected in Rhode Island, Connecticut, eastern Long Island (NY), New

Response of Cowpea (Vigna Unguiculata L) Varieties to Defoliation [PDF]

, 2018
Loss of foliage in cowpea (Vigna unguiculata [L] Walp) as a result of field physiological disorders and/or diseases is detrimental to the growth and development of the crop in both tropical and sub-tropical areas.

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

Plant 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.

Revealing the Key Genetic Basis of Late Leaf Spot Resistance in Peanut by Combining QTL Mapping, QTL‐seq and RNA‐seq

Plant, Cell &Environment, EarlyView.
ABSTRACT Late leaf spot (LLS) is the most widespread and destructive fungal disease affecting peanut worldwide, yet relatively little is known about its genetic basis. In this study, QTL mapping using a 1327‐bin map (derived from 9533 SNP/InDel markers) and multi‐environment phenotypic data repeatedly detected two major LLS‐resistance QTLs on ...

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.
