Borax Promotes Fertility of Brassica napus Better Than Other Boron Species at Suboptimal Supply

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Continuous and sufficient boron (B) supply is essential for achieving maximum yield in Brassica napus. Increasing incidences of environmental water limitation are linked to reduced plant B availability and increased B deficiencies.

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 ...

Tissue location of resistance in apple to the rosy apple aphid established by electrical penetration graphs [PDF]

, 2009
A study of the constitutive resistance of the apple cultivar Florina, Malus domestica Borkh. (Rosaceae), to the rosy apple aphid, Dysaphis plantaginea (Passerini) (Homoptera Aphididae), was performed for the first time by the electrical penetration graph

Seasonal Vascular Tissue Formation in Four Boreal Tree Species With a Focus on Callose Deposition in the Phloem

Frontiers in Forests and Global Change, 2019
We studied the seasonal dynamics of xylem and phloem formation in four boreal tree species that differed in leaf phenology (evergreen vs. winter-deciduous) and wood anatomy (angiosperms vs. gymnosperms).

Preharvest potassium silicate treatments influence the morphological appearance and enhance nutritional composition of almond kernels

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The almond industry requires new strategies to improve almond kernel quality. The use of biostimulants such as potassium silicate (KSi) is an eco‐friendly and non‐polluting alternative. The aim of this work was to investigate the preharvest application of KSi solutions at 2 and 20 mmol L−1 to ‘Peraleja’ almond trees during two ...

RNAi efficiency, systemic properties, and novel delivery methods for pest insect control : what we know so far [PDF]

, 2016
In recent years, the research on the potential of using RNA interference (RNAi) to suppress crop pests has made an outstanding growth. However, given the variability of RNAi efficiency that is observed in many insects, the development of novel approaches

Tree defence and bark beetles in a drying world: carbon partitioning, functioning and modelling. [PDF]

, 2020
Drought has promoted large-scale, insect-induced tree mortality in recent years, with severe consequences for ecosystem function, atmospheric processes, sustainable resources and global biogeochemical cycles.

Stem anatomy and ontogeny of vascular variants in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae)

Nordic Journal of Botany, EarlyView.
An increase in stem thickness and ontogeny of successive cambia, intraxylary cambium, and inter‐and intraxylary phloem is elaborated for the first time in Ipomoea asarifolia (Desr.) Roem. & Schult. (Convolvulaceae). As the plants grew older, several small segments of cambium were initiated simultaneously external to the phloem formed by regular ...

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

Nordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

TreeWatch.net : a water and carbon monitoring and modeling network to assess instant tree hydraulics and carbon status [PDF]

, 2016
TreeWatch.net is an initiative that has been developed to watch trees grow and function in real-time. It is a water- and carbon-monitoring and modeling network, in which high quality measurements of sap flow and stem diameter variation are collected on ...
