為探討碾白機機型對稻米含胚率之影響,並作為水稻育種篩選適合碾製胚芽米新品種(系)時,設定礦製條件之依據,以1987年二期作及1988年一期作在台中區農業改良場收穫之稻谷為材料進行試驗。結果發現胚芽米之含胚率是以稻谷含水率12%者為最高,而含水率16%者為最低,然在本試驗稻谷水分含量範圍內,均以直立式小型碾白機(YamamotoVP-30T)碾製胚芽米時,其理論含胚率高於橫筒式碾白機(McGill No.2)。Yamamoto VP-30T在實際操作上亦比McGill No.2簡便,而且其理論含胚率(碾白度27度時)與循環2~4次時之含胚率呈顯著正相關,放在育種上以Yamamoto VP-30T碾白機碾製2~4次時,其品種間含胚率的高低,應可作為篩選胚芽米品種之參考。
The effect of different modes of milling machine on the quality of ernbryoed rice (embryo-intact rice) was evaluated. The experiments were conducted at Taichung DAIS, with the materials harvested in the 2nd crop of 1987 and 1st crop of 1988. The resulted showed that the highest percentage of ernbryoed grains was obtained when the moisture content of rice grain was adjusted at 12% level. While the lowest percentage of that was obtained at the grain moisture level of 16%. The milling machine Yamamoto VP-30T resulted in a better milling quality in terms of ernbryoed rice than that of McGill No.2 regardless of grain moisture content. The former was found to be much easier to control and operate than the latter. In addition to this, there is a positive correlation between the theoretial rate of ernbryoed grains (at 27º of milling whiteness) and the actural rate of ernbryoed grains after the circulation of rice grains 2-4 times. Therefore, using Yamamoto VP-30T miller at 2-4 times circulation is considered to be a standard method or testing the percentage of ernbryoed grains in breeding program.
