Plant respiration intensity measurement experiment
The intensity of respiration can be expressed as the number of CO2mg released per unit weight of plant material per unit time. The CO2 released by respiration i

Experiments for the quantitative determination of chlorophyll
According to the absorption spectrum of chlorophyll on visible light, the use of spectrophotometer at a particular wavelength to determine its optical density,
Experiments on oxidation and phosphorylation in isolated mitochondria
When sufficient oxygen is supplied to plant tissues, plant cells can oxidize substrates completely. When glucose is fully oxidized as a respiratory substrate, C
Simple identification experiments of plant peroxidases
Peroxidases are metalloproteins containing iron in the porphyrin ring. Peroxidase forms a compound with hydrogen peroxide in which the hydrogen peroxide is acti
Experiments on the antagonistic effects of single-salt toxicity and mixed salts
Monosalt toxicity and antagonism are related to hydrophilic colloids in protoplasm and protoplasmic membranes; the higher the ionic valence, the lower the conce
Experiments on the determination of water potential in plant tissues by the small fluid flow method
The water status of plant tissues can be expressed in terms of water potential. The magnitude of the water potential of plant tissues can, to a certain extent,
Experiments on the selective uptake of mineral elements by plant roots
Monosalt toxicity and antagonism are related to hydrophilic colloids in protoplasm and protoplasmic membranes; the higher the ionic valence, the lower the conce
Simple identification experiments of plant oxidizing enzymes
Oxidases dehydrogenate from metabolites and allow them to combine directly with oxygen to produce water or hydrogen peroxide. Examples include cytochrome oxidas
Experiments on the compositional analysis of plant wounding fluids
Plant root system is not only an important organ to absorb water and mineral elements, but also an important synthetic organ, plant absorbed inorganic salts, so
