Studies and developments related to increasing the nutritional value of rice have been receiving widespread attention. One of the most popular techniques for increasing the nutritional value of rice during processing is germination. This study aims to break the dormancy of rough rice (Oryza sativa L.) cultivar Khao Dawk Mali 105 (KDML105) by using infrared radiation to stimulate seed quality (seed vigour and seed germination were included in this study). This study used a full factorial in a completely randomized design (CRD) with stimulation by different factors including storage periods of 3 5 7 and 9 weeks; infrared wavelengths of 4.00 3.75 and 3.52 m; and duty cycles of radiation of 1 2 and 3 cycles. The feed rate was controlled at 20 kg.hr-1 and the seed moisture content did not exceed 14 wb. It was found that the storage period infrared wavelength and duty cycle of radiation significantly affect the seed quality at P0.05. For good performance we recommend a storage period of 5 weeks an infrared wavelength of 3.75 m and a duty cycle of 2 cycles.

Abstract

Studies and developments related to increasing the nutritional value of rice have been receiving widespread attention. One of the most popular techniques for increasing the nutritional value of rice during processing is germination. This study aims to break the dormancy of rough rice (Oryza sativa L.) cultivar Khao Dawk Mali 105 (KDML105) by using infrared radiation to stimulate seed quality (seed vigour and seed germination were included in this study). This study used a full factorial in a completely randomized design (CRD) with stimulation by different factors including storage periods of 3 5 7 and 9 weeks; infrared wavelengths of 4.00 3.75 and 3.52 m; and duty cycles of radiation of 1 2 and 3 cycles. The feed rate was controlled at 20 kg.hr-1 and the seed moisture content did not exceed 14 wb. It was found that the storage period infrared wavelength and duty cycle of radiation significantly affect the seed quality at P0.05. For good performance we recommend a storage period of 5 weeks an infrared wavelength of 3.75 m and a duty cycle of 2 cycles.
