Fat Extraction - Soxhlet's Fat Extraction Method Experiment
In the determination of the oil content of the sample, usually using organic solvents with a boiling point of less than 60 ℃ as a fat solvent (such as ether an
Experiments on the induction of α-amylase formation by gibberellin
Gibberellins are produced in the dextrinous layer of the embryo after water absorption and germination of barley or wheat seeds. These gibberellins, when releas
Experiments on Plant Damage from Undesirable Environments
When plant tissues are subjected to drought or other adverse conditions, the protoplasmic structure of the cells will be injured, especially the membrane system
Phenylalanine deaminase (PAL)
Phenylalanine ammonia-dissolving enzyme (PAD) plays an important role in regulating the formation of secondary substances such as lignin, phytoalexins, flavonoi
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
Experiments on the effect of potassium ions on stomatal openings
The expansion and contraction of the guard cells on both sides of the stomata directly affects the opening and closing of the stomata, which significantly influ
Determination of coolant content in plant tissues
Phenolic substances in plant tissues are oxidized to Da by polyphenol oxidase, and Da can automatically polymerize into colorful substances and browning occurs.
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
