Experiments on the extraction, isolation, properties and quantitative determination of chloroplast pigments
Chloroplast pigment is an important substance for plants to absorb sunlight energy for photosynthesis. This experiment is to learn the extraction and separation
Experiments to determine the degree of water deficit in plants
The proline content in plants increases when they are dehydrated. The proline content in plants reflects the water situation in plants to a certain extent, and
Experiments for the determination of photosynthetic intensity
Modified half-leaf method is part of the plant symmetrical leaf shade or remove placed in the dark, the other part is left in the light for photosynthesis, afte
Experiments for the identification of plant resistance
The study of plant stress tolerance is important in scientific research and is closely related to production, so it is often necessary to measure the magnitude
Experiments for the determination of respiratory strength
