Abstract:
In this work six samples from Bougainvillea spp1, Citrus Sinesis, Canna Indica, Ixora Coccinia, Bougainvillea spp2 and Citrus Paradisi living under sun light beside 6 samples from the same plants living in shadow were exposed to Nitrogen laser for 0.0125 seconds. The ultrasound wave emitted by them was detected by ultrasound detectors. It was found that Bougainvillea spp1leaves produce ultrasound frequencies 0.0041× 1017 and 0.0042× 1017 Hz, Citrus Sinesis leaves produce frequencies 0.0040× 1017 ,0.0039, 0.0038× 10 17, 0.004× 1017 3 Hz, Canna Indica leaves produced frequencies0.0040× 1017,0.0043× 1017,, 0.0039×1017, 0.0038×1017and 0.0035×1017 Hz, Ixora Coccinia leaves produce frequencies 0.0041× 1017, 0.0043× 1017, 0.0039× 1017 and 0.0038× 1017 Hz, Bougainvillea spp2 leaves produce frequencies
0.0042× 1017 0.0045× 1017 , 0.0039× 1017 0,0034× 1017 , 0.0031× 1017 ,and 0.0043× 1017 Hz . Citrus Paradisi leaves produce frequencies 0,0041×1017,0.0042×1017 and 0.0040×1017 Hz .
