chlorophyll content

Chlorophyll content is highly sensitive for detecting plant nitrogen and sulfur stress, and is commonly used to manage nitrogen fertilization by measuring chlorophyll content. Chlorophyll content is also used to measure other types of stress in many plants, when the measured value of the tested plant is that of a normally fertilized plant At 90%, nitrogen fertilizer needs to be applied. The measurement band of this system is different from most chlorophyll measuring instruments, and it can also measure nitrogen balance index.
Chlorophyll content:T850nm/T720nm

Flavonol content

Flavonoids appear yellow in plants. There is evidence to suggest that they contribute to photoprotection of plants in the ultraviolet spectrum and eliminate reactive oxygen species, thereby protecting plant photosynthesis. Flavonoids can effectively indicate the nitrogen status of plants, and their yellow color can attract pollinating insects.
Flavonol content: fluorescence ratio F660/F375

Anthocyanin content

According to plants Different pH values can appear as red, blue, purple, or colorless. Research has shown that anthocyanins play an important role in temperature protection of plants under stress, attracting pollinating insects and promoting animal seed distribution.
Anthocyanin content: Fluorescence ratio F660/F525

NFI (nitrogen flavonol index)

Chlorophyll and flavonols are good indicators of plant nitrogen status. Under suitable conditions, plants produce chlorophyll and small amounts of flavonols. When nitrogen is insufficient, plants produce more flavonols or carbon based compounds,The sensitivity of NFI to leaf age and thickness is lower than that of standard chloroplasts.
nitrogen -Flavonol Index: Chlorophyll to Flavonol Measurement Ratio (T850nm/T720nm)/(F660nm/F375nm)
The ratio fluorescence method has many advantages and can be used to measure very small and opaque samples. The measurement methods for anthocyanins and flavonols are both ratio fluorescence methods.

Measure berry cap

MPM-100 measures the relative maturity of grapes by removing the thin berry cover with a blade, which can be used to measure the relative maturity of grapes with an instrument.
