Determination of stomatal opening and closing conditions in plants
Stomata are the main channel for gas exchange between plant leaves and the outside world, and the distribution, density, shape, size and opening and closing of
Seed assay by triphenyltetrazolium chloride (TTC) method
Viable seed embryos undergo continuous redox reactions during respiration, and the hydrogen shed reduces the coenzymes (NAD or NADP). When TTC penetrates into t
Determination of osmotic potential of plant cells
The osmotic potential of plant cells mainly depends on the concentration of solutes in the vesicles, and some plants actively accumulate solutes in their cells
Determination of malondialdehyde in plant tissues
Determination of malondialdehyde content in plant tissues is to understand the factors of malondialdehyde (malondialdehyde, MDA ) formation in living organisms;
Solution culture of plants and observation of deficiency diseases
Essential elements are mineral elements that are necessary to maintain the normal physiological activities of plants. To determine whether various elements are
Assay of nitrate reductase activity
Nitrate reductase is a key enzyme in the metabolic action of plant nitrogen and is associated with the ability of crops to take up and utilize nitrate nitrogen.
Single-salt toxicity and inter-ionic antagonism
The phenomena of single salt toxicity and inter-ionic antagonism are simple experiments to illustrate the importance of the balance of various ions (various ion
Determination of nitrate reductase activity
NO3- taken up by plant roots must be metabolically reduced before it can be further utilized by the plant. Nitrate reductase (EC.1.6.6.1, abbreviated as NR) is
