Abstract

Preserving and obtaining quality seeds are a pressing need in the face of climate change and in relation to alimentary sovereignty in our country. The use of emitting systems of different wavelengths to improve seeds can contribute to reducing the vulnerability of cultivated species to agricultural pests. The work is carried out with the objective of improving the quality of the seeds by means of high brightness light emitting diodes systems of different wavelengths (BIOFIE-ULTRA), resulting from previous investigations developed in a joint work INISAV-CUJAE, through the Scientific Chair of Science for Life. The investigation was based on the irradiation of seeds of corn, cucumber, green beans and lettuce with red and green light, during different times of exposure and using seeds of the same batch as control or control. The results achieved show an increase in germination percentage between 40 and 80% in those with latency or stress problems, and an increase in the germination rate of 24 to 48 hours in the seeds that have a high percentage, as well as an increase in the height of the seedling superior to 24% and of 70 and 80% the length of the root.
