Floral color and scent are two important components of floral design. Although previous studies on floral design have been mostly descriptive. The exploration on their quantitative studies can provide key evidence to learn pollination mechanisms. Our study focuses on recently developed methods for the quantitative measurement of floral color and floral scent. We introduce three floral color measurement and plotting methods, including color chart, colorimeter and spectrometer. Dynamic headspace collection-adsorption, adsorption-solvent desorption and solid phase micro-extraction are the three frequently-used floral scent collection methods and gas chromatography-mass spectrometry and zNose are usually used in floral scent analysis. Lastly, gas chromatography with electroantennographic detector, Y-tube olfactometer and flight cage experiment can help us to evaluate insect behavior.
