中文摘要 | 分析近年來相關試驗中,稻米蛋白質含量的變異,探討影響米粒蛋白質含量的因素,供各界參考應用,期對國內稻米品質改良有所助益。結果發現不同的品種間蛋白質含量有差異存在,本研究中參試的早熟稉稻、糯稻及秈稻的蛋白質含量均比中晚熟稉稻高。二期作的蛋白質含量亦比一期作高, 1998年二期作的蛋白質含量比 1997年二期作高,顯示不同的栽培季節及年度間的蛋白質含量有差異存在。台稉 9號及台稉 14號以栽培在彰化縣北斗鎮的蛋白質含量較高,台稉 15號、台稉 16號及台農 67號則以栽培在南投縣草屯鎮的蛋白質含量較高,顯示不同栽培地點間的蛋白質含量有差異存在,同時稻米的蛋白質含量亦隨氮肥用量的增加而增加。水稻以劍葉 0~1/3面積罹患白葉枯病時的蛋白質含量最低,隨著劍葉罹病面積的增加,蛋白質含量亦有增加的趨勢。台中縣大甲鎮稻米品質競賽中,不同參賽戶間的蛋白質含量仍有差異,糙米的蛋白質含量比白米高,且糙米與白米二者間的蛋白質含量有正相關存在。 |
英文摘要 | The purpose of this study was to investigate the variability of crude protein content of rice and to explore the factors affecting them. Results showed significant difference in crude protein content among varieties, seasons and locations. Crude protein content was generally higher in early maturity japonica rice, glutinous rice and indica rice compared to medium-late maturity japonica rice. Crude protein content in the second crop was higher than that in the first crop. It was also noted that crude protein content in the second crop of 1998 was higher than that of 1997. The crude protein content of rice from Peitou had the highest for Tai Keng 9 and Tai Keng 14, but from Tsaotun the highest were Tai Keng 15, Tai Keng 16 and Tainung 67. Crude protein content also increased with an increase in the amount of nitrogen fertilizer and in diseased lesion area of bacterial leaf blight of rice plants. Comparing rice grain quality in Tachia, the results showed that there was a variation of crude protein content among rice samples. The average crude protein of brown rice was higher than that of milled rice. There was also a positive correlation between the crude protein content of brown rice and milled rice. The results can provide farmers, breeders, processors and testers to improve rice grain quality. |
