Effects of row direction and row spacing on maize leaf senescence.

PLoS One 2019 18;14(4):e0215330. Epub 2019 Apr 18.

Northeast Institute of Geography and Agroecology, CAS, Changchun, China.

To analyze three row orientations (south-north, east-west, southwestern 20°) and two row spacings ('65 + 65', '160 + 40'), we investigated the effect of row orientation and planting pattern on photosynthetic performance, physiological and biochemical indicators related to the aging of leaves. Results revealed that during maturity stage, in north-south and east-west, the initial fluorescence (Fo) at '65 + 65' were higher than those under'160 + 40'; the maximum quantum yield of PS2 photochemistry(ΦP0), basal quantum yield of non-photochemical processes in PS2(ΦN0)of the lower leaves and photosynthetic rate of the upper and ear leaves under'160 + 40'were higher than those under'65 + 65'. The polyphenoloxidase (POD) activities of leaves at different positions under '160 + 40' were higher than that under'65 + 65', while the malondialdehyde (MDA) content was lower. Read More

Evolutionary agroecology: Trends in root architecture during wheat breeding.

Evol Appl 2019 Apr 26;12(4):733-743. Epub 2018 Dec 26.

State Key Laboratory of Grassland Agro-ecosystems, Institute of Arid Agroecology, School of Life Sciences Lanzhou University Lanzhou Gansu Province China.

Root system characteristics determine soil space exploration and resource acquisition, and these characteristics include competitive traits that increase individual fitness but reduce population performance. We hypothesize that crop breeding for increased yield is often a form of "group selection" that reduces such "selfish" traits to increase population yield. To study trends in root architecture resulting from plant breeding and test the hypothesis that increased yields result in part from group selection on root traits, we investigated root growth and branching behavior in a historical sequence of wheat () cultivars that have been widely grown in northwestern China.

Wood ash effects on growth and cadmium uptake in Deschampsia flexuosa (Wavy hair-grass).

Environ Pollut 2019 Mar 27;249:886-893. Epub 2019 Mar 27.

Center for Bioenergy Recycling - ASHBACK, Terrestrial Ecology Section, Department of Biology, University of Copenhagen, Universitetsparken 15, DK2100, Copenhagen, Denmark. Electronic address:

Wood ash recycling to forests is beneficial because it regains nutrients and prevents acidification, but wood ash application is restricted due to its cadmium (Cd) content. We question if Cd in wood ash represents a problem, since decreases in Cd bioavailability due to ash-induced pH changes may counteract increased total Cd concentration. We studied effects of wood ash (0, 3, 9 and 30 t ha) and lime (pH increase equivalent to the wood ash treatments) on growth and Cd uptake in Deschampsia flexuosa. Read More

Land Surface Temperature Response to Irrigated Paddy Field Expansion: a Case Study of Semi-arid Western Jilin Province, China.

Sci Rep 2019 Mar 27;9(1):5278. Epub 2019 Mar 27.

Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, Changchun, 130102, China.

The irrigated paddy fields have expanded greatly at semi-arid western Jilin province of China in recent over ten years, the sources of which are rain-fed cornfields, swamp meadow and saline alkali land mainly. Based on regional land use data, remote sensing data and meteorological data, this paper evaluates the land surface temperature changes response to land surface biophysical processes changes resulting from land use change (LUC), and dissociates the effect of radiative change (albedo) and non-radiative change (evapotranspiration and turbulent process) quantitatively using the energy redistribution factor. The results show that, the total land surface temperature changes based on energy redistribution factor are consistent with that based on remote sensing data on the whole, which have significant and different seasonal variations for agriculture adjustment of rain-fed cornfields to irrigated paddy fields and nature land reclamation.

Characterizing diversity of food systems in view of sustainability transitions. A review.

Agron Sustain Dev 2019 17;39(1). Epub 2018 Dec 17.

1Farming Systems Ecology Group, Wageningen University and Research, PO Box 430, 6700AK Wageningen, The Netherlands.

Dominant food systems are configured from the productivist paradigm, which focuses on producing large amounts of inexpensive and standardized foods. Although these food systems continue being supported worldwide, they are no longer considered fit-for-purpose as they have been proven unsustainable in environmental and social terms. A large body of scientific literature argues that a transition from the dominant food systems to alternative ones built around the wider principles of sustainable production and rural development is needed.

Genetically Engineered Crops: Importance of Diversified Integrated Pest Management for Agricultural Sustainability.

Front Bioeng Biotechnol 2019 20;7:24. Epub 2019 Feb 20.

Research Division Agroecology and Environment, Agroscope, Zurich, Switzerland.

As the global population continues to expand, utilizing an integrated approach to pest management will be critically important for food security, agricultural sustainability, and environmental protection. Genetically engineered (GE) crops that provide protection against insects and diseases, or tolerance to herbicides are important tools that complement a diversified integrated pest management (IPM) plan. However, despite the advantages that GE crops may bring for simplifying the approach and improving efficiency of pest and weed control, there are also challenges for successful implementation and sustainable use.

Maize productivity and soil properties in the Loess Plateau in response to ridge-furrow cultivation with polyethylene and straw mulch.

Sci Rep 2019 Feb 28;9(1):3090. Epub 2019 Feb 28.

College of Food science and Engineering, Gansu Agricultural University, Lanzhou, 730070, China.

Ridge-furrow with full film mulching (RFFM) is widely used in the Loess Plateau (LP) to increase maize yield. However, continuous RFFM application may cause excessive depletion of soil organic carbon (SOC) and soil water storage (SWS). The present study tested four production systems, namely, (1) RFFM; (2) ridge-furrow with polyethylene film and straw mulching (RFFSM); (3) non-contoured seedbed with film mulching (FFM); and (4) non-contoured seedbed without mulching (CK) in 2013 and 2014 to identify an optimal technique to increase maize yield yet minimizing the negative effects.

Reduced caterpillar damage can benefit plant bugs in Bt cotton.

Sci Rep 2019 Feb 25;9(1):2727. Epub 2019 Feb 25.

Agroscope, Research Division Agroecology and Environment, Reckenholzstrasse 191, 8046, Zurich, Switzerland.

Bt cotton was genetically modified to produce insecticidal proteins targeting Lepidopteran pests and is therefore only minimally affected by caterpillar damage. This could lead to reduced levels of inherent, systemically inducible defensive compounds in Bt cotton which might benefit other important cotton herbivores such as plant bugs. We studied the effects of plant defense induction on the performance of the plant bug Lygus hesperus by caging nymphs on different food sources (bolls/squares) of Bt and non-Bt cotton which were either undamaged, damaged by Bt tolerant caterpillars, or treated with jasmonic acid (JA).
