Intercropping, which grows at least two crop species on the same pieces of land time, can increase grain yields greatly. Legume-grass intercrops are known to overyield because legume nitrogen fixation. However, many agricultural soils deficient in phosphorus. Here we show that a new mechanism overyielding, phosphorus mobilized by one increases growth second grown alternate rows, led large yield phosphorus-deficient soils. In 4 years field experiments, maize (Zea mays L.) overyielded 43% and...
Symbiotic nitrogen (N2 ) fixation plays a vital role in sustainable agriculture. Efficient N2 requires various materials, including phosphate (Pi); however, the molecular mechanism underlying transport of Pi into nodules and bacteroids remains largely unknown. A nodule-localized transporter, GmPT7, was functionally characterized soybean (Glycine max) its yield investigated via composite whole transgenic plants. GmPT7 protein localized to plasma membrane showed activity for yeast. Altered...
Abstract Water and nitrogen stresses are major constraints for agricultural forest productivity. Although the effects of water scarcity or stress on plant growth, physiology, yield have been widely studied, few studies assessed combined both stresses. In present study, we investigated different forms (NO 3 − N, NH 4 + -N, a combination NO N -N) antioxidant enzyme activity, osmotic regulatory substances, assimilation in Chinese fir ( Cunninghamia lanceolata ) plantlets under drought (induced...
As a primary sediment source, gully erosion leads to severe land degradation and poses threat food ecological security. Therefore, identification of susceptible areas is critical the prevention control erosion. This study aimed identify prone using four machine learning methods with derived topographic attributes. Eight attributes (elevation, slope aspect, degree, catchment area, plan curvature, profile stream power index, wetness index) were as feature variables controlling occurrence from...
Gullies are primary sediment sources that restrict sustainable agricultural development by reducing the quality of soil and destroying farmlands. In black regions Northeast China, intensive exploitation unreasonable cultivation result in severe erosion malignant expansion gully erosion. However, few susceptibility (GES) assessments have been performed this area, despite being an effective tool to explain potential occurrence. study, four adjacent catchments were selected Keshan County,...
Introduction A better understanding of xylem hydraulic characteristics in trees is critical to elucidate the mechanisms forest decline and tree mortality from water deficit. As well as temperate forests growing arid regions, subtropical tropical are also predicted experience an increased frequency intensity climate change-induced drought near future. Methods In this study, 1-year-old Cunninghamia lanceolata seedlings (a typical species southern China) were selected for a continuous...
Mineral accumulation in plants under drought stress is essential for tolerance. The distribution, survival, and growth of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.), an evergreen conifer, can be affected by climate change, particularly seasonal precipitation drought. Hence, we designed a pot experiment, using 1-year-old plantlets, to evaluate effects simulated mild drought, moderate severe which corresponds 60%, 50%, 40% soil field maximum moisture capacity, respectively. A...
To improve efficiency in the use of water resources water-limited environments such as North China Plain (NCP), where winter wheat is a major and groundwater-consuming crop, application water-saving irrigation strategies must be considered method for sustainable development resources. The initial objective this study was to evaluate validate ability CERES-Wheat model simulation predict grain yield, biomass yield (WUE) responses different management methods NCP. results from evaluation...
Abstract Background Carbohydrate partitioning and utilization is a key determinant of growth rate yield in plants crops. There are few studies on crops field conditions. In Arabidopsis , starch accumulation leaves negative indicator rate. Results Here, we wished to establish if could potentially be marker for such as maize. We characterized daily patterns non-structural carbohydrate (NSC) at different stages over two seasons maize hybrids the field. 27 commercial hybrids, found significant...
Rhizosphere and endophytic microbiota significantly affect plant growth development by influencing nutrient uptake stress tolerance. Herein, root rhizosphere soil of Acacia species were collected analyzed to compare the structural differences bacterial communities. High-throughput 16S rRNA gene sequencing technology was employed analyze A total 4249 OTUs identified following sequence analysis. The contained more than soil. Principal component analysis (PCA) hierarchical cluster indicated...
The Chinese fir Cunninghamia lanceolata (Lamb.) Hook. is an important timber conifer species in China. Much has been studied about fir, but the distribution of non-structural carbohydrates (NSCs) among different organs (needles, branch, stem, and roots) under drought stress remains poorly understood. In this study, we used one-year-old C. plantlets to evaluate effects simulated four water regimes, i.e., adequate or control, light drought, moderate severe corresponding 80%, 60%, 50%, 40%,...
Papaya ( Carica papaya L.) fruit flesh and seed growth, respiration, sugar accumulation, the activities of sucrose phosphate synthase (SPS), (SS), acid invertase (AI) were determined from anthesis for ≈150 days after (DAA), full ripe stage. Sugar began to accumulate in between 100 140 DAA, maturation had occurred. SPS activity remained low throughout development. The SS was high 14 DAA decreased less than one-fourth within 56 then constant during remainder AI young increase 90 reached a peak...
