Based on panel data from 30 provinces 2001 to 2018 in China, this paper explores the effects and mechanisms of green urbanization forestry total factor productivity (FGTFP) context carbon neutral strategy using a two-way fixed model instrumental variables. The results show that: Firstly, as sector with ecological economic benefits, ignoring sink output tends make FGTFP overestimated. Secondly, ...
Yield is a function of root distribution and activity. In flood conditions, root growth and efficiency are essential for crop productivity. The goal of this study was to investigate the effect of different irrigation regimes on the root development, yield and yield components of green pepper (green Hashemi cultivars). This study, which was based on a completely randomized design with three repl...
Breeding programs with the aim to enhance yield productivity under abiotic stress conditions during the reproductive stage of crops is a top priority in the era of climate change. However, the choice of exploring stay-green or senescence phenotypes, which represent an opposing physiological bearing, are explored in cereal breeding programs for enhanced yield stability to a different extent. Thu...
The importance of the eukaryotic algal CO(2)-concentrating mechanism (CCM) is considered in terms of global productivity as well as molecular phylogeny and diversity. The three major constituents comprising the CCM in the majority of eukaryotes are described. These include: (i) likely plasma- and chloroplast-membrane inorganic carbon transporters; (ii) a suite of carbonic anhydrase enzymes in s...
Low food availability is a major structuring force in deep-sea benthic communities, sustaining only very low densities of organisms in parts of the abyss. These low population densities may result in an Allee effect, whereby local reproductive success is inhibited, and populations are maintained by larval dispersal from bathyal slopes. This slope-abyss source-sink (SASS) hypothesis suggests tha...
Research on Green Innovation Performance of Manufacturing Industry and Its Improvement Path in China
Green innovation, which combines “innovation-driven” and “green development,” is one of the most powerful ways to overcome resource environmental constraints enhance manufacturing industry sustainability. Based on innovation value chain perspective, green process decomposed into two stages: scientific technological R&D achievement transformation. Then, using three-stage DEA Malmquist index ...
Organisms have their own patterns of distribution and biological organizations functioning in the natural system. Community is one of the hierarchies of ecological organizations composed of different species of organisms interacting in space and time. Photosynthesis is the fundamental biological process by which radiant energy is converted to chemical energy and thereby readily becomes availabl...
Nitrogen deficiency promotes lipid formation in many microalgae, but also limits growth and lipid productivity. In spite of numerous studies, there is poor understanding of the interactions of growth and lipid content, the time course of lipid accumulation and the magnitude of nitrogen deficiency required to stimulate lipid formation. These relationships were investigated in six species of olea...
Improvement of leaf photosynthesis is an important strategy for greater crop productivity. Here we show that the quantitative trait locus GPS (GREEN FOR PHOTOSYNTHESIS) in rice (Oryza sativa L.) controls photosynthesis rate by regulating carboxylation efficiency. Map-based cloning revealed that GPS is identical to NAL1 (NARROW LEAF1), a gene previously reported to control lateral leaf growth. T...
