Thus the experiences of dry seeds were irradiated with different doses four lots in 2009 and 2010 corresponding variants V1-V4 (5-20 minutes). The experimental results were analyzed in parallel with a control group of seeds that did not apply to treatment of red laser diodes.Inallthe seedsanalyzedfromthetwoflower speciesstudiedgerminationcapacityandthatthe growth ofseedlings, determining germinationpercentageseverytwodays for3weeks. Results have shown a percentage of germination higher than control group of seeds (75%) for all repetitions of variant V4 (95%), with exposure time of 20 minutes (1.53 joules / cm 2) to treatment with red light produced by laser modulated at audio frequency
