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
RNA-mediated gene silencing assay
Down-regulation of endogenous gene expression by post-transcriptional horizontal gene silencing (PTGS) is a key to characterize plant gene function. Many RNA le
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
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
Phenylalanine deaminase (PAL)
Phenylalanine ammonia-dissolving enzyme (PAD) plays an important role in regulating the formation of secondary substances such as lignin, phytoalexins, flavonoi
Determination of plant transpiration rate
The speed of transpiration is related to the speed of mineral salt transportation in the plant and leaf temperature, etc. The transpiration rate can be used as
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
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
