Advantages and disadvantages of measuring seed vigor by fluorescence method

Advantages and disadvantages of measuring seed vigor by fluorescence method;

1, advantages:

It has a good effect on cruciferous seeds such as Chinese cabbage and radish.

2. Disadvantages:

Not suitable for seeds whose fluorescence will be weakened or lost after aging and death. In the latter case, direct observation should be adopted.

Characteristics of fluorescence analysis:

Fluorescence analysis is an advanced analysis method, which is more widely used than electron probe method, mass spectrometry, spectrometry and polarography, which is inseparable from the many advantages of fluorescence analysis.

The equipment used in fluorescence analysis is relatively simple, such as visual fluorometer, fluorescence photometer, etc., and the structure is very simple, so it can be manufactured by itself.

Compared with mass spectrometer, polarograph and electron probe instrument, it is many times cheaper in cost. The biggest characteristics of fluorescence analysis are: high sensitivity, strong selectivity and convenient use. There are not many instruments with these three characteristics at the same time.
