- Experiments for the determination of free proline in plants SummaryPlants grown under normal environmental conditions have low levels of free proline, but under adversity (e.g., drought, cold, salt, etc.) the free proline content in plants can increase 10-100 times, so it has been proposed that the free proline content can be used as an indicator of ...
- Experimental colorimetric determination of inter-root pH SummaryWhile absorbing nutrients, the plant root system overflows H+, OH-, HCO3- and other organic substances, which changes the inter-root pH, and thus affects the inter-root nutrient status (e.g., ionic state, solubility, etc.). Therefore, inter-root pH has an important role in plant nutrition ...
- Diffusion Observation Experiment in Small Holes SummaryExperiments to deepen the understanding of efficient diffusion of water through small pores.Operation methodDiffusion Observation Experiment in Small HolesPrincipleThe stomata on the leaf surface are the main channels for carbon dioxide and gaseous water molecules to and from the leaf. ...
- Root Volume Measurement Experiment SummaryThe root system is the main organ of the plant body, and its growth is closely related to the speed of water and mineral uptake by the plant. Therefore, it is often necessary to measure the growth of the root system. Through the experiment, master the principle and method of root volume ...
- Experiments on the effect of environmental factors on plant water exhalation SummaryTo understand the influence of environmental factors on the vital activities of the root system by observing the spitting phenomenon of plants under different environmental conditionsOperation methodExperiments on the effect of environmental factors on plant water ...
- Plant transpiration rate measurement experiment SummaryTranspiration is an important process of water metabolism in plants. The speed of transpiration is related to the rate of upward transport of mineral salts and other salts in the plant, as well as leaf temperature, etc. In particular, the rate of transpiration can also be used as an ...
- Plant stomatal detection experiment by fixation method SummaryThrough the experiment, master the principle and method of observing the stomatal opening and closing condition of plant leaves by the fixation method.Operation methodPlant stomatal detection experiment by fixation methodPrincipleAnhydrous ethanol can make the plant cells quickly ...
- Experimental determination of plant root vigor by alpha-naphthylamine method SummaryThis experiment was mainly used to determine plant root vigor.Operation methodExperimental determination of plant root vigor by alpha-naphthylamine methodPrincipleThe α-naphthylamine adsorbed on the root surface will be oxidized by the plant roots to produce red 2-hydroxy-1-naphthylamine ...
- Plant stomatal infiltration assay experiment SummaryThrough the experiment, master the principle and method of observing the stomatal opening and closing condition of plant leaves by the infiltration method.Operation methodPlant stomatal infiltration assay experimentPrincipleVarious liquids have different wetting power on plant leaves, the ...
