Neighbouring plants modify maize root foraging for phosphorus: coupling nutrients and neighbours for improved nutrient‐use efficiency

New Phytologist (2019)

Deshan Zhang Yang Lyu Hongbo Li Xiaoyan Tang Ran Hu

Summary Nutrient distribution and neighbours can impact plant growth, but how neighbours shape root‐foraging strategy for nutrients is unclear. Here, we explore new patterns of plant foraging for nutrients as affected by neighbours to improve nutrient acquisition. Maize ( Zea mays ) was grown alone (maize), or with maize (maize/maize) or faba bean ( Vicia faba ) (maize/faba bean) as a neighbour on one side and with or without a phosphorus (P)‐rich zone on the other in a rhizo‐box experiment. Maize demonstrated root avoidance in maize/maize, with reduced root growth in ‘shared’ soil, and increased growth away from its neighbours. Conversely, maize proliferated roots in the proximity of neighbouring faba bean roots that had greater P availability in the rhizosphere (as a result of citrate and acid phosphatase exudation) compared with maize roots. Maize proliferated more roots, but spent less time to reach, and grow out of, the P patches away from neighbours in the maize/maize than in the maize/faba bean experiment. Maize shoot biomass and P uptake were greater in the heterogeneous P treatment with maize/faba bean than with maize/maize system. The foraging strategy of maize roots is an integrated function of heterogeneous distribution of nutrients and neighbouring plants, thus improving nutrient acquisition and maize growth. Understanding the foraging patterns is critical for optimizing nutrient management in crops.

Biomass partitioning and ionomics of Macadamia with high manganese and low phosphorus concentrations

Functional Plant Biology (2023)

Xin Zhao Yang Lyu Qianqian Dong Xiyong He Yue Hai

Knowledge of the ionome of plant organs helps us understand a plant’s nutritional status. However, the ionome of Macadamia (Proteaceae), which is an important nut-producing tree, remains unknown. We aimed to characterise the allocation of biomass and nutrient-partitioning patterns in three macadamia genotypes. We excavated 15 productive trees (three cultivars at 21 years of age; two cultivars at 16 years of age) in an orchard. Biomass, nutrient concentrations, and contents of roots, stems, branches, and leaves were analysed. Dry weight of roots, stems, branches and leaves accounted for 14–20%, 19–30%, 36–52%, and 12–18% of total plant weight, respectively. No significant difference was found in the total biomass among the cultivars at the same age. Compared with most crop plants, macadamia had low phosphorus (P) concentrations in all organs (<1 g kg−1), and low leaf zinc (Zn) concentration (8 mg kg−1). In contrast, macadamia accumulated large amounts of manganese (Mn), with a 20-fold higher leaf Mn concentration than what is considered sufficient for crop plants. Leaves exhibited the highest nutrient concentrations, except for iron and Zn, which exhibited the highest concentrations in roots. The organ-specific ionomics of Macadamia is characterised by low P and high Mn concentrations, associated with adaptation to P-impoverished habitats.

Optimizing Nitrogen Application for Growth and Productivity of Pomegranates

Agronomy (2020)

Silit Lazare Yang Lyu Uri Yermiyahu Yehuda Heler Alon Ben‐Gal

Quantification of actual plant consumption of nitrogen (N) is necessary to optimize fertilization efficiency and minimize contamination of earth resources. We examined the performance of fruit-bearing pomegranate trees grown in soilless media and exposed to eight N-fertigation treatments, from 5 to 200 mg N L−1. Reproductive and vegetative indices were found to be optimal when 20 to 70 mg N L−1 was supplied. Nitrogen application levels over 70 mg L−1 reduced pomegranate development and reproduction. N uptake in low-level treatments was almost 100% and decreased gradually, down to 13% in 200 mg N L−1 treatment. N usage efficiency was maximized under 20 mg N L−1, in which case 80% to 90% of added N was taken up by the trees. At high N application, its efficiency was reduced with less than 50% utilized by the trees. Leaf N increased to a plateau as a function of increasing irrigation solution N, maximizing at ~15 to 20 mg N g−1. Therefore, analysis of diagnostic leaves is not a valid method to identify excessive detrimental N. The results should be valuable in the development of efficient, sustainable, environmentally responsible protocols for N fertilization in commercial pomegranate orchards, following adaptation and validation to real soil field conditions.

The niche complementarity driven by rhizosphere interactions enhances phosphorus‐use efficiency in maize/alfalfa mixture

Food and Energy Security (2020)

Liyang Wang Baicheng Hou Deshan Zhang Yang Lyu Kai Zhang

Abstract Rhizosphere interactions between intercropping maize and alfalfa to increase phosphorus (P) acquisition remain largely unknown. This study aimed to investigate the mechanisms underlying niche complementarity to increase P acquisition in the maize/alfalfa mixture by influencing root/rhizosphere interactions. Maize was grown alone (single maize) or with maize (maize/maize) or alfalfa (maize/alfalfa) with low P (30 mg P kg −1 soil) and high P (150 mg P kg −1 soil) supplies. The target maize had greater shoot biomass and P content when grown with alfalfa than maize. Compared with maize, alfalfa had higher secretion of carboxylates and acid phosphatase, suggesting a stronger capacity to mobilize soil P. Phosphorus deficiency also increased the specific root length and the proportion of thin roots (diameter < 0.2 mm) in alfalfa, and intercropped alfalfa had higher carboxylates secretion than monocropped one, indicating that alfalfa root traits were modified by both soil P supply and the identity of neighbor. Increased soil P availability by alfalfa root exudation and improved rhizosphere environment by thin alfalfa roots promoted shoot growth and P acquisition of maize in the maize/alfalfa mixture. The presence of maize increased the secretion of carboxylates from alfalfa roots, suggesting that the root interactions between maize and alfalfa are crucial for improving P‐use efficiency and productivity in intercropping.

Effects of nitrogen fertilization on pomegranate fruit, aril and juice quality

Journal of the Science of Food and Agriculture (2019)

Yang Lyu Ron Porat Uri Yermiyahu Yehuda Heler Doron Holland

Abstract BACKGROUND Nitrogen (N) fertilization influences plant growth and yield, and may also affect fruit quality. For two consecutive seasons, we examined the effects of various N fertilization levels – 5 to 200 mg L −1 – on pomegranate fruit, aril and juice quality. Evaluations included fruit and aril weight, size and color, appearance of peel blemishes, internal black rot and nutritional composition of extracted juices. RESULTS Nitrogen fertilization affected pomegranate fruit, aril and juice quality. The most pronounced effects were observed in trees grown under the lowest N fertilization level, which bore smaller fruit and arils, the latter with lighter color; the fruit suffered from sunburn, and the juice had lower total soluble solid, acidity and anthocyanin contents. The proportion of edible aril weight per total fruit weight gradually increased with an increase in N fertilization concentration. In contrast, N fertilization did not affect peel color, roughness or cracking incidence. Black rot incidence increased with increasing N concentration. CONCLUSIONS Nitrogen fertilization affected pomegranate fruit, aril and juice quality, and the total number of marketable fruits per tree. The optimal N fertilization levels, which were most beneficial for achieving high‐quality marketable fruit, were between 40 and 100 mg L −1 . © 2019 Society of Chemical Industry

Spatial and Interannual Variability in Distributions and Cycling of Summer Biogenic Sulfur in the Bering Sea

Geophysical Research Letters (2019)

Chengxuan Li Baodong Wang Zi‐Cheng Wang Jiang Li Gui‐Peng Yang

Abstract In the Bering Sea, summer dimethylsulfide (DMS) and dimethylsulfoniopropionate (DMSPd and DMSPp) exhibited substantial spatial and interannual variations during 2012–2016, encompassing both cold (2012) and warm (2014 and 2016) temperature regimes. Summer average chlorophyll a , DMS, and DMSPd concentrations in the upper water increased significantly, paralleling a 1.6 °C increase in seawater temperature. High DMS/DMSPp regions in the upper 50 m at 177°E–175°W extended both north‐eastward and south‐westward, which were associated with elevated phytoplankton biomass and concurrent proportion of dinoflagellates in phytoplankton community in warm years. Simultaneously, these patches spread vertically throughout the upper 200 m in warm years, which corresponded with rapid bacteria consumption and abundant small copepods at the 50–200‐m layer in 2014 and 2016. Starting from 4.88 μmol/(m 2 day), summer average DMS fluxes increased sharply by threefold to fivefold in response to a warming of 2.8 °C in the surface water during 2012–2016.
