The responses of macroalgae to ocean acidification could be altered by availability of macronutrients, such as ammonium (NH4+). This study determined how the opportunistic macroalga, Ulva australis responded to simultaneous changes in decreasing pH and NH4+ enrichment. This was investigated in a week-long growth experiment across a range of predicted future pHs with ambient and enriched NH4+ tr...

While genotype-environment interaction is increasingly receiving attention by ecologists and evolutionary biologists, such studies need genetically homogeneous replicates-a challenging hurdle in outcrossing plants. This could be potentially overcome by using tissue culture techniques. However, plants regenerated from tissue culture may show aberrant phenotypes and "somaclonal" variation. Here, ...

The chlorophyll fluorescence parameter Fv/Fm (maximum photosynthetic efficiency of optical system II) is an intrinsic index for exploring plant photosynthesis. Hyperspectral remote sensing technology can be used rapid nondestructive detection parameters. Existing studies show that there a good correlation between the vegetation and Fv/Fm. However, due to limited hyperspectral information reflec...

The maximum quantum efficiency of photosystem II (Fv/Fm) is a widely used indicator photosynthetic health in plants. Remote sensing Fv/Fm using MS (multispectral) and RGB imagery has the potential to enable high-throughput screening plant agricultural ecological applications. This study aimed estimate spring wheat at an experimental base Hanghou County, Inner Mongolia, from 2020 2021. images we...

Mexican lime is one of the commercial citrus cultivars in the world, which is commonly used as a citrus rootstock in the southern regions of Iran. This cultivar is one of the most sensitive citrus cultivars to cold stress and is used as a cold-sensitive plant in many citrus studies. This study aimed to investigate the effect of melatonin (0 and 500 μM), mannitol (0 and 50 μM), acetic acid (0 an...

in order to evaluate of physiological traits, related to drought tolerance, an experiment was carried out in controlled condition. the experiment was conducted to assess the effect of drought stress on photosynthesis, chlorophyll fluorescence and photosynthetic pigments in two tolerant genotypes (mcc392 & mcc877) and two susceptible genotypes (mcc68 & mcc448) were grown in drought stress (25% f...
