Abstract Maize (Zea mays L., the third most important cereal crop after wheat and rice, is the major kharif (summer) crop of rainfed areas in Pakistan. The yield per hectare and total production of maize in Pakistan is low versus an exponentially increasing population. The objective of this work was to study the interactive effects of phytohormones [Gibberellic acid (GA), Sodium nitroprusside (SNP), Abscicic acid (ABA) and kinetin (KIN)] on morphological, physiological and biochemical parameters during the germination of maize seeds. Seeds were presoaked in different hormones, separately or in combinations. Priming with GA+SNP+ABA+KIN enhanced the total More >

Abstract Wheat is one of the most important protein sources for human beings. Several food products are elaborated from this cereal, such as bread. Mexican wheat breeding programs are focused on to identify those genotypes with high yields and bread quality. Therefore, the aim of this study was to evaluate the environmental effects over the Physicochemical and Bromatological quality parameters of Cal Blanco F2011, Matchett F2011 and RSM-Norman F2008 wheats sown at the experimental fields at Mexicali, Baja California, Querendaro, Michoacán and Tarimoro, Guanajuato, Mexico during the autumn-winter growing cycle for two consecutive years (2014-2016) under… More >

Abstract Genetic diversity and relatedness of 17 water primrose (Ludwigia hyssopifolia) accessions in Thailand were estimated using morphological characters and random amplified polymorphic DNA (RAPD) markers. Eight morphological characters were diverse among the accessions. However, some accessions could not be distinguished from one another based on these morphological characters alone. Unweighted pair-group arithmetic average (UPGMA) analysis of these characters separated these 17 accessions into 2 major clusters. Among the 5 RAPD primers used, a total of 68 fragments (150 to 2000 bp) were amplified, showing a polymorphism percentage of 80%. The polymorphic information content (PIC) among accessions… More >

Abstract Leaf δ¹³C is widely used to explain plant strategies related to resource availability in different environments. However, the coupled response of leaf δ¹³C to precipitation and temperature as well as the relationship between leaf δ¹³C and leaf traits remain unclear. The leaf δ¹³C and its relationship with leaf traits [leaf size (LS), leaf length (LL), leaf width (LW), leaf length to width ratio (L:W), specific leaf area (SLA) and mass-based leaf nitrogen concentration (N_mass)] were investigated on the dominant shrub species Nitraria tangutorum Bobr. in the arid region (Dengkou and Minqin) of northwestern China under the simulated increasing precipitation… More >

Abstract Rapid and precise assessment of biodiversity is a central issue in conservation biology and biodiversity science. Higher taxonomic units and life form-based morphospecies were utilised to assess plant diversity patterns at the habitat scale in temperate meadow steppe, Songnen Plain, China. Patch area, taxonomic composition (families and genera) and life form (based on Raunkiaer’s life forms, and stem and root growth forms) were recorded in five communities. Taxonomic unit-based hierarchical diversity indices (HDI) and life form-based hierarchical diversity indices (HLDI) were calculated. Twenty-six families, 67 genera, and 87 species were recorded in the five communities.… More >

Abstract The objective of this study was to investigate extracts from the peels of Annona squamosa L. (purple sugar apple), Annona reticulata L. (custard apple), Chrysophyllum cainito L. (green star apple), and Melicoccus bijugatus Jacq. (mamoncillo), as potential sources of anti-HIV-1 agents. Methanolic extracts from the peels of the aforementioned tropical fruits were obtained by maceration. Antiviral activity was evaluated through HIV-1 RT inhibition by extracts, using a non-radioactive immuno/colorimetric assay (Lenti RT Activity Assay, Cavidi Tech). Assay was performed according to the protocol provided by the manufacturer. Extracts from the peels of A. squamosa, A. reticulata, and C. cainito showed high More >

Abstract Plant competition for soil resources is common in semiarid rangelands. Plants have various, alternative mechanisms to deal with soil resource acquisition. They include (1) length, weight and proliferation of roots, (2) root length density, and (3) root colonization by arbuscular mycorrhiza. In rangelands of Argentina, plants are exposed to herbivory after natural fires. As a result, knowledge on how these disturbances impact root traits is important for outlining guidelines focused on rangeland management and improvement. Our aim was to analyze the effects of defoliation after a controlled burning on root traits (1) to (3) on… More >

Abstract Abiotic stresses like salt stress and soil compaction are responsible for increased ethylene production which may adversely affect crop growth. A field experiment was conducted to evaluate the response of seed inoculation with ACC-deaminase containing rhizobacteria (Pseudomonas fluorescens and Pseudomonas syringae) in the presence of recommended or half of a recommended rate of inorganic fertilizers at different growth stages of fodder maize in a compacted saline-sodic soil. At both fertilizer rates, seed inoculation with P. fluorescens and P. syringae significantly improved all growth parameters over the control treatment. After 30, 60 and 75 days of sowing, treatment with recommended… More >

Abstract Underground railway vibration source strength is one of the key values used for environmental impact assessment and the evaluation of mitigation measure’s performance. However, currently there is no international standard of measuring the underground railway vibration source strength for such purposes. The available local standards and industrial guidelines do not agree on measurement locations as well as the metrics for presenting the source strength. This has caused many confusions. This paper aims to study the suitable measurement location and metrics using the data from a large scale field-testing carried out at the Nanchang underground railway… More >

Abstract In this work, we have developed a novel machine (deep) learning computational framework to determine and identify damage loading parameters (conditions) for structures and materials based on the permanent or residual plastic deformation distribution or damage state of the structure. We have shown that the developed machine learning algorithm can accurately and (practically) uniquely identify both prior static as well as impact loading conditions in an inverse manner, based on the residual plastic strain and plastic deformation as forensic signatures. The paper presents the detailed machine learning algorithm, data acquisition and learning processes, and validation/verification More >
