APPLICATION OF LASER TREATMENT WITH RADIATION STIMULATION IN ANNUAL SPECIES OF SEED GERMINATION DIANTHUS CARYOPHYLLUS - VAR CHABAUD AND PETUNIA HYBRIDA

Journal Title: Current Trends in Natural Sciences - Year 2012, Vol 1, Issue 1

Abstract

Additional illumination with red light produced by laser diodes in continuous and different exposure times, was applied to seeds from two species of annual flowers: Garofita Dianthus caryophyllus - var. CHABAUD; FEUER KONING and romanian Petunia hybrid variety "WHITE CASCADE. The experimental results presented in the present study are a continuation of research initiated in 2009 ((P. Niculita , S. Danaila-Guidea, O. Livadariu , M. Ristici, J. Ristici si F. Burnichi, 2009 )and were aimed at testing the germination of seeds and development morphology induced by treatment effect based on laser radiation fields in the early stages of development of seeds under the effect of intensity light in the spectral range 640 nm - 660nm. Sets of seeds were irradiated once mounted on the first day of the experiment at different energy doses by changing exposure time. 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. In all the seeds analyzed from the two flower species studied germination capacity and that the growth of seedlings, determining germination percentages every two days for 3 weeks. 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.
