Dose Splitting Increases Selection for Both Target‐Site and Non‐Target‐Site Fungicide Resistance—A Modelling Analysis

Plant Pathology, Volume 74, Issue 4, Page 1152-1167, May 2025.
Epidemiological model shows that dose splitting increases selection for fungicide resistance, especially for partial resistance mechanisms that only affect efficacy at lower fungicide concentrations. ABSTRACT Fungicide resistance management principles recommend that farmers avoid splitting the total dose applied of a fungicidal mode of action (MoA ...

Soybean seed yield distribution within the canopy as affected by nitrogen supply

Crop Science, Volume 65, Issue 2, March/April 2025.
Abstract Soybean (Glycine max [L.] Merr.) seed yield is influenced by the seasonal availability of resources (i.e., nutrients, light, and water). While nitrogen (N) supply is becoming a soybean yield‐limiting factor, the N‐induced effect in seed yield components is still unclear.

Abscisic acid increase correlates with the soil water threshold of transpiration decline during drought

Plant, Cell &Environment, Volume 47, Issue 12, Page 5067-5075, December 2024.
Abstract By regulating carbon uptake and water loss by plants, stomata are not only responsible for productivity but also survival during drought. The timing of the onset of stomatal closure is crucial for preventing excessive water loss during drought, but is poorly explained by plant hydraulics alone and what triggers stomatal closure remains ...

Morphogenetic and structural characteristics of guinea grass pastures submitted to three frequencies and two defoliation severities. [PDF]

, 2011
It was evaluated the morphogenic and structural characteristics of guinea grass under rotational at three grazing intervals and two defoliation intensities. Grazing intervals corresponded to the time needed by the forage canopy to reach 90, 95 or 100% of

Desenvolvimento vegetativo de duas cultivares de oliveira na fase de muda Vegetative development of two olive cultivars in seedling phase

Ciência Rural, 2012
O desenvolvimento de plantas, influenciado pela temperatura do ar, pode ser estimado através do conceito de filocrono, definido como o intervalo de tempo entre o surgimento sucessivo de folhas em uma haste, sendo o tempo expresso em °C dia e o filocrono ...

Model assisted phenotyping of processes involved in rice response to drought: case study of a tropical japonica population during vegetative phase : [Abstract, P 7.15] [PDF]

, 2009
Tropical japonica rice is frequently exposed to drought in upland ecosystems. Its drought tolerance is poor compared to other crops but the group has great genetic, in part unexploited diversity in adaptations.

A Functional Analysis of Inflorescence Architecture in Musa L. (Musaceae)

Food and Energy Security, Volume 13, Issue 5, September/October 2024.
ABSTRACT Inflorescence architecture underpins sexual reproduction in wild Musa species and productivity in edible banana cultivars. In a functional analysis, we identified the apical inflorescence and lateral ‘cushion’ meristems and the change in flower type as the three primary components that generate inflorescence architecture. Five genotypes of two

Comprehensive evaluation of the DSSAT‐CSM‐CERES‐Wheat for simulating winter rye against multi‐environment data in Germany

Agronomy Journal, Volume 116, Issue 4, Page 1844-1868, July/August 2024.
Abstract Crop models are valuable tools for simulating and assessing genotype‐by‐environment interactions. In most studies, these models are parameterized based on crop data from a few sites and years, which often limits their applicability to a broader geographic context.

Thermal Time as a Parameter to Determine Optimal Defoliation Frequency of Perennial Ryegrass (Lolium perenne L.) and Pasture Brome (Bromus valdivianus Phil.)

Agronomy, 2020
The herbage mass and nutritional value of harvested forage are fundamental determinants of the production potential of pastoral systems. The objective of this study was to evaluate the growth dynamics and accumulated herbage mass expressed in dry matter (
