Research on biophotonics in agricultural issues

For agricultural biophotonic measurements both spontaneous photon emission and delayed luminescence technologies are used. Delayed luminescence is a “time-resolved” spectrum analytical method.

Spontaneous photon emission is mainly applied to characterize the defense systems of plants. The quality of the defense system predicts the capacity of plants to protect themselves against attack from pathogens such as bacteria, fungi, nematodes and insects.

Delayed luminescence provides information about vitality of a biological product. It is based on the integral structural quality in relation to the developmental state and capacity of a product. Vitality is a novel quality marker of food products and complimentary to commonly used tests for chemical content and structural properties of a product.

Delayed luminescence is used:
  • to predict germination capacity of seeds,
  • to estimate stage of growth and ripening,
  • to predict vitality under storage conditions.
