Sampling roots to capture plant and soil functions

Functional Ecology, Год журнала: 2017, Номер 31(8), С. 1506 - 1518

Опубликована: Апрель 18, 2017

Summary Roots vary in anatomy, morphology and physiology, both spatially (different parts of the same root system) temporally (plastic changes, ageing), suggesting that trait measurements are strongly affected by sampling categories. In this context, it is urgent to clarify functional significance current categories (e.g. fine roots first order, three orders, ≤1 mm or ≤2 mm), establish guidelines for choosing between methods revise ontology account differences traits measured on distinct Here, we used a worldwide database fine‐root test hypothesis values – with link functions were generally different We observed indeed clear break first‐order all other categories, smaller but substantial orders category, demonstrating globally methodologies capture roots. Our synthesis suggests present advantages pitfalls no single method can appropriately tackle main challenge ecology: i.e. linking plant ecosystem truly comparable way across plants. argue instead small set complementary standardized necessary linkages forms functions. To assist experimenters selecting adequate developed decision table following logical questions: (i) what function must be addressed; (ii) involved (iii) should these Challenging, strengthening expending such common reference framework would step towards wider comparability future datasets.

Insight Into the Role of PGPR in Sustainable Agriculture and Environment

Frontiers in Sustainable Food Systems, Год журнала: 2021, Номер 5

Опубликована: Июнь 30, 2021

A multitude of roles is played by microbes in food and agriculture that include nutrient cycling management, organic matter decomposition fermentation. Plant growth promoting rhizobacteria (PGPR), representing microbial groups with ability colonizing plant roots, influence through various indirect direct modes order to promote its and/or protect it from diseases or damage due insect attack. Thus, PGPR research has received renewed interest worldwide. Increasing number crop-specific are being commercialized these days. Approaches like seed-inoculation soil application either alone combination bacterial culture/product for increased availability phosphate solubilisation, potassium sulfur oxidation, nitrogen fixation, iron, copper chelation gaining popularity. Arbuscular mycorrhizal fungi (AMF) root fungal symbiont improve management abiotic stress such as phosphorus deficiency. involves production indole acetic acid (IAA), ammonia (NH 3 ), hydrogen cyanide (HCN), catalase, etc. also uptake altering the level hormone enhances surface area increasing girth shape, thereby helping absorbing more nutrients. facilitate seed germination, seedling crop yield. An array including Pseudomonas, Azospirillum, Azotobacter, Klebsiella, Enterobacter, Alcaligenes, Arthrobacter, Burkholderia, Bacillus , Serratia enhance growth. Various Pseudomonas sp. have demonstrated significant increase yield different agricultural crops, wheat. Hence, developing a successful formulation, candidate should possess characteristics high rhizosphere competence, extensive competitive saprophytic ability, enhancing ease mass production, broad-spectrum action, safety toward environment compatibility other partnering organisms.

Climate Change Impacts and Adaptation Strategies of Agriculture in Mediterranean-Climate Regions (MCRs)

Sustainability, Год журнала: 2019, Номер 11(10), С. 2769 - 2769

Опубликована: Май 15, 2019

The world’s five Mediterranean-climate regions (MCRs) share unique climatic regimes of mild, wet winters and warm dry summers. Agriculture in these is threatened by increases the occurrence drought high temperature events associated with climate change (CC). In this review we analyze what would be effects CC on crops (including orchards vineyards), how cropping farming systems could adapt to CC, are social economic impacts, as well strategies used producers CC. rainfed areas, water deficit occurs mostly during flowering grain filling stages (terminal stress), which has large detrimental productivity crops. Orchards vineyards, cultivated irrigated will also vulnerable due a reduction available for irrigation an increase evapotranspiration. Adaptation agriculture MCRs requires integrated that encompass different levels organization: crop system (sequence management techniques particular agricultural field) system, includes farmer.

Abstract. Accurate high-resolution actual evapotranspiration (ET) and gross primary production (GPP) information is essential for understanding the large-scale water carbon dynamics. However, substantial uncertainties exist in current ET GPP datasets China because of insufficient local ground measurements used model constraint. This study utilizes a water–carbon coupled model, Penman–Monteith–Leuning Version 2 (PML-V2), to estimate 500 m at daily scale. The parameters PML-V2(China) were well calibrated against observations 26 eddy covariance flux towers across nine plant functional types China, indicated by Nash–Sutcliffe efficiency (NSE) 0.75 root mean square error (RMSE) 0.69 mm d−1 ET, respectively, NSE 0.82 RMSE 1.71 g C m−2 GPP. estimates get small Bias 6.28 % high water-balance annual 10 major river basins China. Further evaluations suggest that newly developed product better than other typical products (MOD16A2, SEBAL, GLEAM, MOD17A2H, VPM, EC-LUE) estimating both Moreover, accurately monitors intra-annual variations croplands with dual-cropping system. new data showed that, during 2001–2018, use experienced significant (p<0.001) increase (8.99 yr−2 0.02 mm−1 H2O yr−1, respectively), but non-significant (p>0.05) (0.43 yr−2). indicates vegetation exhibits huge potential sequestration little cost resources. provides great opportunity academic communities various agencies scientific studies applications, freely available https://doi.org/10.11888/Terre.tpdc.272389 (Zhang He, 2022).

Enhancing climate change resilience in agricultural crops

Current Biology, Год журнала: 2023, Номер 33(23), С. R1246 - R1261

Опубликована: Дек. 1, 2023

Climate change threatens global food and nutritional security through negative effects on crop growth agricultural productivity. Many countries have adopted ambitious climate mitigation adaptation targets that will exacerbate the problem, as they require significant changes in current agri-food systems. In this review, we provide a roadmap for improved production encompasses effective transfer of knowledge into plant breeding management strategies underpin sustainable agriculture intensification resilience. We identify main problem areas highlight outstanding questions potential solutions can be applied to mitigate impacts Although translation scientific advances lags far behind technology, consider holistic approach, combining disciplines collaborative efforts, drive better connections between research, policy, needs society.
