Photoreceptors and Plant Responses to Light

20.6K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

Plant Tissues

6.6K
Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions. Different tissues work together to perform a unique function and form an organ. Organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system and a root system. The shoot system consists of two portions: the vegetative (non-reproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant,...

Differential Staining Technique01:26

Differential Staining Technique

141
Differential staining is an essential microbiological technique that exploits variations in cell wall structures to classify and identify microorganisms. It facilitates the distinction of bacteria, aiding in diagnostic and research applications. Two of the most widely used differential staining methods are Gram staining and acid-fast staining, both of which rely on the chemical and structural differences in bacterial cell walls.Gram Staining TechniqueGram staining differentiates bacteria by...

Simple Staining Technique

222
OverviewStaining techniques in microscopy enhance the visualization of microorganisms by increasing contrast and allowing the differentiation of cellular structures. Simple staining is one of the fundamental methods used to observe the basic morphological characteristics of microorganisms, including their size, shape, and arrangement. This method relies on the application of a single dye to stain the entire cell, producing a clear contrast between the cell and the background.FixationFixation is...

Area of Science:

  • Agricultural Science
  • Plant Pathology
  • Food Science

Background:

  • Black spot disease, caused by Alternaria alternata, significantly impacts postharvest winter jujubes.
  • Accurate detection of this disease is crucial for maintaining fruit quality and reducing losses during storage.

Purpose of the Study:

  • To investigate the potential of hyperspectral imaging (HSI) for detecting black spot disease in winter jujubes during postharvest storage.
  • To evaluate the effectiveness of Visible and Near-Infrared (Vis-NIR) and Short-Wave Infrared (SWIR) spectral regions for disease detection.

Main Methods:

  • Acquisition of HSI data in Vis-NIR (400-1000 nm) and SWIR (1000-2000 nm) spectral regions.
  • Measurement of physical (color, weight loss) and chemical (soluble solids, chlorophyll) parameters.
  • Application of Partial Least Squares Discriminant Analysis (PLS-DA) and Principal Component Analysis (PCA) for data analysis.

Main Results:

  • Spectral reflectance showed a downtrend in both Vis-NIR and SWIR ranges during infection.
  • PLS-DA models achieved high discrimination accuracy for disease detection (>92.31% for Vis-NIR, >91.03% for SWIR).
  • PCA of Vis-NIR HSI spectra effectively visualized diseased areas on infected jujubes.

Conclusions:

  • Vis-NIR and SWIR HSI techniques show strong potential for detecting black spot disease in postharvest winter jujubes.
  • Vis-NIR HSI is particularly effective for visualizing the spatial distribution of disease on the fruit.
