Relationship of floral morphology and biology of yellow melon hybrids with the attractiveness of pollinators. [PDF]

, 2016
To increase the productivity of melon, new hybrids have been released. The aim of this study was to c ompare the differences in morphology and floral biology of two yellow melon hibrids and these could influence the attractiveness of the pollinators. The

A Continental United States Climatology of Precipitation Whiplash Using a New Event‐Based Definition

International Journal of Climatology, EarlyView.
Precipitation whiplash events have been increasingly studied over the recent decade, however, no studies have considered the spatial coherence of grid points in their examination. Therefore, we developed an algorithm that defines spatially coherent precipitation whiplash events on the subseasonal‐to‐seasonal timescale between 1915 and 2020 which can be

Temporal stability of Heliconia spp. flower stem production

Ornamental Horticulture, 2016
The instability of heliconia flower stem production may be related to climatic variation. Therefore, that information is very important for planning the species production throughout Brazil, mainly in northeast region.

Compound Hot‐Dry Days (CHDDs) and Their Implications on Maize Yields in the Free State Province, South Africa

International Journal of Climatology, EarlyView.
Compound hot‐dry events occurring during the maize growing period are increasing significantly (p < 0.05) with time, with the median values ranging from 93 to 120 days. El Niño Southern Oscillation (ENSO) influences the variability of compound hot‐dry events with high significance (p < 0.05) positive Pearson correlation.

Boron availability and fertilizer response of maize in soils from sub‐Saharan Africa

Journal of Plant Nutrition and Soil Science, EarlyView.
Abstract Background and aims Low boron (B) availability is associated with strongly weathered, coarse‐textured, and low organic matter soils, widespread in sub‐Saharan Africa (SSA). It is unknown to what extent B fertilization can increase maize yields in SSA.

Floral Resources Used by Euglossini Bees (Hymenoptera: Apidae) in Coastal Ecosystems of the Atlantic Forest

Psyche: A Journal of Entomology, 2012
In spite of playing an important ecological role as pollinators of tropical ecosystems, orchid bees are still poorly known regarding their floral resources.

Potential pollinators of understory populations of Symphonia globulifera in the Neotropics.

Journal of Pollination Ecology, 2018
One difference between the forest canopy and the understory is that animals pollinate the majority of understory species in the tropical wet forest. Pollinators active in the understory are also different from those in the forest canopy and are adapted ...

Effect of Vapor Pressure Deficit on Nutrient Uptake and Growth of Four Tomato Varieties Grown Hydroponically at Low Nutrient Concentrations

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Marginal water sources, such as wastewater, have been proposed as the basis for hydroponic nutrient solutions to improve the resource efficiency of greenhouse‐based tomato production. Such water sources are often low in plant‐available nutrient concentrations, and uptake and use efficiency of these nutrients may vary widely among ...
