Plant phenotyping is an emerging discipline in plant biology. Quantitative measurements of functional and structural traits help to better understand gene-environment interactions support breeding for improved resource use efficiency important crops such as bean (Phaseolus vulgaris L.). Here we provide overview state-of-the-art approaches addressing three aspects plants: belowground roots, aboveground shoots transport/allocation processes. We demonstrate the capacity high-precision methods...
• Root colonization by arbuscular mycorrhizal fungi (AMF) was investigated in industrially polluted grassland characterized exceptionally high phosphorus levels (up to 120 g kg−1 soil). Along a pollution-induced nitrogen gradient, soil and tissue element concentrations of Artemisia vulgaris plants their status were determined. Additionally, we compared mycorrhization rates above-ground biomass A. at N-fertilized control plots the N-poor area. Despite P concentrations, from N-deficient plots,...
Live imaging methods have become extremely important for the exploration of biological processes. In particular, non-invasive measurement techniques are key to unravelling organism–environment interactions in close-to-natural set-ups, e.g. highly heterogeneous and difficult-to-probe environment plant roots: rhizosphere. pH CO2 concentration main drivers rhizosphere Being able monitor these parameters at high spatio-temporal resolution is utmost importance relevant interpretation underlying...
• Translocation is shown of phosphorus, nitrogen, potassium and magnesium to a P-deficient host from ectomycorrhizal fungal hyphae. Mycorrhizal (with Paxillus involutus) nonmycorrhizal spruce (P. abies) seedlings were grown in two-compartment sand-culture system. Hyphal translocation nutrients the inner compartment (penetrated only by hyphae) was measured using mass balance (for N, P K) or stable isotope (15N 25Mg) methods. Addition hyphal strongly stimulated growth, this also increased both...
We have detailed knowledge from controlled environment studies on the influence of root temperature plant performance, growth and morphology. However, in all was kept spatially uniform, which motivated us to test whether a vertical gradient soil affected development biomass production. Roots barley seedlings were exposed three uniform treatments (10, 15 or 20°C) (20-10°C top bottom). Substantial differences production architecture occurred 30-day-old plants. Shoot plants increased by 144...
Root temperature has long been considered an essential environmental factor influencing the plant’s physiology. However, little is known about effect of root on quality food produced by plant, especially that horticultural crops. To fill this gap, two independent cooling experiments (15 °C vs. 20 and 10 °C) were conducted in autumn 2017 spring 2018 hydroponics with Chinese broccoli (Brassica oleracea var. alboglabra Bailey) under greenhouse conditions. The aim was to investigate plant growth...
The contribution of the extramatrical mycelium to N and P nutrition mycorrhizal Norway spruce ( Picea abies (L.) Karst.) was investigated. Seedlings either inoculated with Paxillus involutus (Batsch) Fr. or non‐mycorrhizal were grown in a two compartment sand culture system where hyphae separated from roots by 45 μm nylon net. Nutrient solution hyphal contained 1.8 m NH 4 + 0.18 H 2 PO − no P. Aluminium added as tracer mass flow not detected plant compartment, indicating that measurements...
Understanding the effects of root temperature on plant growth and key food components horticultural crops under greenhouse conditions is important. Here, we assess impact cooling fruit quality two cocktail tomato cultivars ( Lycopersicon esculentum cv “Amoroso” “Delioso”) during winter 2017-2018 summer 2018. Plants were grown hydroponically rockwool different temperatures (16–27°C 10°C) from 2 nd inflorescence to harvest inside greenhouse. A 10°C was controlled independently air (18–23°C in...
Article On the Distribution and Transport of Mineral Elements in Xylem, Cambium Phloem Spruce (Picea abies [L.] Karst.) was published on January 1, 1997 journal Holzforschung (volume 51, issue 6).
In laboratory and greenhouse experiments with potted plants, shoots roots are exposed to temperature regimes throughout a 24 h (diel) cycle that can differ strongly from the regime under which these plants have evolved. field, often lower temperatures than shoots. When root-zone in Ricinus communis was decreased below threshold value, leaf growth occurred preferentially at night inhibited during day. Overall, expansion, shoot biomass growth, root elongation ramification rapidly, carbon...
Abstract Aims Magnesium (Mg) deficiency is detrimental to plant growth. However, how plants respond Mg via regulation of uptake and allocation yet not fully understood. In this study, we tested whether isotope compositions (δ 26 Mg) associated with mass balance the could be used as an indicator trace subsequent translocation processes under sufficient low-Mg supply conditions. We aimed at using stable fractionation a novel proxy for nutrient cycling in plants. Methods grew wheat ( Triticum...
Salinity is a major constraint for crop health and productivity, particularly on arid, semiarid, otherwise marginal soils, such as quarry residue. Quarries are main pillar of national income in Palestine but have long-lasting toll the environment. We examined barley (Hordeum vulgare L.), another Palestinian economy one most important crops world, this regard its tolerance to salinity stress. This study first evaluate impact (50, 85, 120, 175 mM NaCl) seed germination, early growth stage,...
