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
Fluorescence method to detect seed experiments
Plant seeds often exist in many substances that can produce fluorescence under ultraviolet irradiation, such as certain flavonoids, coumarins, vegetal, phenolic
Solution culture of plants with mineral deficiency experiments
Plants must absorb certain essential mineral elements for their normal growth and development. If an essential element is missing, it will show specific deficie
A test for determining the growth zones of leaves of dicotyledonous plants
Different stages in the plant growth cycle show a certain rhythmic pattern, the growth of plants or organs is often limited to certain areas, the observation of
Experiments on the compartmentalized method of measuring the growth area of dicotyledonous plant stems
Different stages in the plant growth cycle show a certain rhythmic pattern, the growth of plants or organs is often limited to certain areas, the observation of
Seed activity assay by red ink staining
The protoplasmic membrane of living cells has the ability to selectively absorb substances, while the protoplasmic membrane of dead cells loses this ability, so
Seed Viability Bromothymolan (BTB) Method Identification Experiment
Where viable seeds can constantly respire, absorbing O2 from the air while releasing CO2, CO2 dissolves in water to form H2CO3, which is unstable and dissociate
Experiments on the determination of the growth zones of stems and leaves of monocotyledonous plants
Different stages in the plant growth cycle show certain rhythmic patterns, and the growth of plants or organs is often limited to certain areas, so the observat
