Intercropping maintains soil fertility in terms of chemical properties and enzyme activities on a timescale of one decade
Springer Science and Business Media LLC - - 2015
Overyielding (i.e., mixtures of crops yielding higher than expected when compared with monocultures) and increased nutrient acquisition have been found in many intercropping systems. However, there are very few published studies on long-term changes in soil chemical and biological properties in intercropping systems compared to sole cropping. A field experiment was established in 2003 in Gansu pro......
The role of histidine kinase signalling in response to salt stress
Springer Science and Business Media LLC - - Trang 1-15 - 2023
Salt stress is a global environmental problem, which affects various biochemical and physiological processes in plants and significantly decreases the quantity and quality of the yield. NaCl is the main driver of NaCl-mediated effects because the accumulation of sodium ions (Na+) in plant tissues disrupts the homeostasis of other ions and may lead to secondary stresses. Two-component signalling (T......
Stemflow nutrient inputs to soil in a successional hardwood forest
Springer Science and Business Media LLC - Tập 140 - Trang 249-254 - 1992
Stemflow and throughfall from a regenerating (8-year-old) southern Appalachian hardwood forest were collected to examine the relative importance of tree bole nutrient leaching in response to acid deposition. Samples from nine (2 m2) stemflow collection plots were analyzed for four dormant season and 11 growing season rainstorm events. Results showed that, relative to throughfall fluxes, stemflow a......
Effects of forest conversion and recovery age on fine root multi-element stoichiometry in subtropical forests
Springer Science and Business Media LLC - Tập 492 - Trang 675-686 - 2023
Fine root multi-element stoichiometric coupling is essential to maintain terrestrial ecosystem functions. Although forest conversion has been a major driver globally in recent decades, its effect on multi-element stoichiometric coupling remains poorly understood. This study examined the ratios of fine root N or P relative to exchangeable cations (i.e., K, Ca, and Mg) along a chronosequence of seco......
Effect of Enhanced Calcium Supply on Aluminum Toxicity in Relation to Cell Wall Properties in the Root Apex of Two Wheat Cultivars Differing in Aluminum Resistance
Springer Science and Business Media LLC - Tập 276 - Trang 193-204 - 2005
The present study was conducted to investigate the effects of enhanced Ca supply on Al toxicity in relation to cell wall properties in two wheat (Triticum aestivum L.) cultivars differing in Al resistance. Seedlings of Al-tolerant Inia66 and Al-sensitive Kalyansona cultivars were grown in complete nutrient solutions for 4 days then subjected to treatment solutions containing Al (0, 50 μM) and Ca (......
Towards understanding the traits contributing to performance of pearl millet open-pollinated varieties in phosphorus-limited environments of West Africa
Springer Science and Business Media LLC - Tập 407 - Trang 243-259 - 2015
Pearl millet [Pennisetum glaucum (L.) R. Br.] open-pollinated varieties, which are the predominant cultivars, have never been systematically evaluated for adaptation to low-soil phosphorus (P), a major constraint on pearl millet production in West Africa (WA). We evaluated grain yield (GY), flowering time (FLO), harvest index (HI), and residual grain yields (RGY) of 102 open-pollinated varieties f......
Simultaneously reducing the intensity and increasing the frequency of sand movements promotes the performance of Artemisia ordosica seedlings in dune environments
Springer Science and Business Media LLC - - 2024
Windblown sand movements, i.e., wind denudation and sand burial, pose a strong selective pressure on dune vegetation. Dune plants commonly receive repeated wind denudation or sand burial. Therefore, simultaneously examining the role of sand movement intensity and frequency in shaping dune vegetation is critical for dune biodiversity conservation and ecological restoration. However, studies of this......
Influence of scion cultivar on the rhizosphere microbiome and root exudates of Phaseolus vulgaris in grafting system
Springer Science and Business Media LLC - - 2024
Grafting is a commonly used technique in horticulture and agriculture. The rhizosphere microbiome is critical for plant growth and performance, however, knowledge of the effect of grafting on rhizosphere microbial assemblages is still limited. Here, we use grafting systems of common beans (Phaseolus vulgaris) to study the effects of scion cultivar and grafting on rhizomicrobiome and root exudates.......
Effects of elevated atmospheric CO2 and its interaction with temperature and nitrogen on yield of barley (Hordeum vulgare L.): a meta-analysis
Springer Science and Business Media LLC - Tập 475 - Trang 535-550 - 2022
The general aim of this meta-analysis is to synthesize and summarize the mean response of barley yield variables to elevated CO2 (eCO2) and how temperature and nitrogen (N) affect the CO2-induced yield responses of barley. A meta-analysis procedure was used to analyze five yield variables of barley extracted from 22 studies to determine the effect size and the magnitude concerning eCO2 and its int......
