SPECTRUM OF ULTRASOUND PRODUCED BY SOME PLANT LEAVES EXPOSED TO NITROGEN LASER

In this work six samples from Bougainvillea spp1, Citrus Sinesis, Canna Indica, Ixora Coccinia, Bougainvillea spp2 and Citrus Paradisi living under sun light beside another six samples from the same plants living in shadow were exposed to Nitrogen laser for few seconds. The ultrasound wave emitted by them was detected by ultrasound detectors. It was found that Bougainvillea spp1 leaves produce ultrasound frequencies: (0.0041and 0.0042X) Hz, Citrus Sinesis leaves produce frequencies: (0.0040X; 0.0039 X 1017; 0.0038X; 0.0043XHz, Canna Indica leaves produced frequencies: (0.0040X ; 0.0043X; 0.0039X0.0038Xand 0.0035X )Hz, Ixora Coccinia leaves produce frequencies: (0.0041X; 0.0043X; 0.0039X and 0.0038) Hz, Bougainvillea spp2 leaves produce frequencies (0.0042X;0.0045X;0.0039X,0,0034X,0.0031X and 0.0043XHz). Citrus Paradisi leaves produce frequencies (0,0041X, 0.0042X and 0.0040X) Hz.
