Defoliation management and boron application as a strategy to reduce poor fruit set and improve the quality of ‘Merlot’ grapes

Acta Scientiarum. Agronomy
‘Merlot’ grapevines hold significant importance in Brazilian viticulture, particularly within the high-altitude region of Santa Catarina. However, they often experience a physiological disorder known as poor fruit set and shot berries, which results in ...

Amaranth as a Dual-Use Crop for Leafy Greens and Seeds: Stable Responses to Leaf Harvest Across Genotypes and Environments

Frontiers in Plant Science, 2019
Dual-use production systems that utilize the green leaves as well as seeds from amaranth are highly promising for small-scale farmers around the world. The leaves are an important source of nutrients for farming families, while seeds can provide income ...

Satire and Silence Under Authoritarian Rule: Cotton and Pesticide Perceptions in Tajikistan

Journal of Agrarian Change, EarlyView.
ABSTRACT Over the past 70 years, agricultural chemicals have become a mainstay of cotton farming in Central Asia. This growing reliance on agrochemicals has not remained uncontested. This article analyses the politics of pesticides in Soviet and post‐Soviet Tajikistan by examining how, and to what extent, pesticides have featured in graphic satire, an ...

Interval and intensity of defoliation on the growth, senescence and defoliation fluxes and equilibrium of associated grasses [PDF]

, 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 ...

The classification of machines for vineyard defoliation in relation to production quality

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Defoliation fulfilment in correct terms, range and intensity effects highly on conditions of bunches and quantity of their contentual matters. Due care reduction of foliar surface together with sunshine allows better access of air to the proximity of ...

Functional memory of drought affects leaf chemical defenses and microbial interactions in aspen

New Phytologist, EarlyView.
Experimental design of the common garden study. Summary Drought is an important driver of tree mortality, but its long‐term impacts on trait expression remain poorly understood. Leaves are a key interface at which trees respond to abiotic stress, and foliar traits such as chemical defenses and microbial communities may play a role in determining post ...

Linking drought strategy to climate‐of‐origin in a widespread C4 grass: hydraulic traits, xylem anatomy and stomatal behaviour in Themeda triandra

New Phytologist, EarlyView.
Climate‐of‐origin of Themeda triandra populations used in this study. Summary Hydraulic, stomatal, and anatomical traits strongly influence plant performance under drought, but the extent to which these trait‐types are coordinated and relate to climate‐of‐origin remains vastly underexplored in herbaceous species relative to woody plants.

Coupled decline in growth and fine‐branching signals the onset of drought‐induced European beech mortality

New Phytologist, EarlyView.
Conceptual synthesis of drought‐induced mortality in European beech. Summary Severe and recurrent droughts have caused widespread canopy decline and mortality in European forests. Drought‐induced mortality occurs when structural damage and physiological dysfunction impair a tree's ability to recover, yet it remains unclear when trees transition from ...
