In: Misr Journal of Agricultural Engineering 2017.v.34(2)Summary: In this work, three types of light used for Carml'aJ' fruits sterilization namely helium-neon (He-Ne) green laser at wavelength 543.5 nm. ultraviolet ( UV) light at wavelength 245 nm and helium-neon (HeNe) red laser at wavelength 632.8 nm with exposure times ( 1. 3. 5. 10 and 15 min. ) with the aim ofstudying the effect for type of radiation. exposure time and their interaction on Caraway fruits. lm'estigated the measurements dimensions from length, width thickness. volume. diameter geometric. diameter area. frontal area, transverse area. sphericity lvith constant moisture to some of sterilization treatments for Carum Carvi. L. fruits. Also in this work studied the correlation for length! width, length! thickness. width! thickness. frontal areal transverse area. sphericity/ frontal area. sphericity/ transverse area, geometric diameter! area diameter, sphericity/ geometric diameter and sphericity/ area diameter. The obtained results indicated that sterilization treatment by He-Ne red laser at doses of 3 and 10 min. recorded the significant effects as increased in essential oil percentage. moisture content. Also the sterilization treatment by ultraviolet radiation at dose of 10 min. recorded Significant effect in carbohydrate. Meanwhile, concerning germination percentage. there was an observable increased in germination percent with wavelength 632.8 nm with dose of3 min. and ultraviolet radiation (UV) at lvavelength 245 nm with dose of 15 min. Finally, it is recommend that using sterilization by helium-neon green at 10 min. in order to eliminate the microbial load.
