中文摘要 | 本試驗目的係利用幼穗分化期之分蘗數及當時植株葉綠素計值估測水稻成熟期之產量。本試驗在2008年第二期作及2009年第一期作於雲林縣、嘉義縣、台南市等三地區進行田間試驗調查,每期作均調查41個田區,試驗材料為水稻臺南11號。試驗調查項目為每一田區水稻幼穗分化期之分蘗數及葉色值(葉綠素計值),並於成熟期調查單位面積產量及其構成因素。由試驗結果顯示稻穀產量之四個構成因素,與產量間之關係雖部分未呈顯著之正相關,但單位面積總粒數(單位面積穗數與每穗粒數之乘積)與稻穀產量間之關係極為密切。由此,本研究以水稻幼穗分化期之分蘗數及葉色值調查數據,進行成熟期稻穀產量之預測,結果顯示在三個地區均以第一期作之結果較第二期作為佳。 |
英文摘要 | The project aims to modeling grain yield using the tillers number and chlorophyll meter determined value at panicle initiation stage in rice Tainan 11. This experiment was undertaken from 41 fields during the second crop season of 2008 to the first crop season of 2009 in Yunlin, Chiayi, and Tainan regions. The result showed that only partial of positive correlation between the four yield components and grain yield. However, the grain yield is highly correlated to total grain numbers (produced from panicle number and grain number per panicle). In addition, the result indicated that predicting model from the first crop season was better than that for the second crop season according to the measurement of tiller number and leaf color. We suggested that to increase sampling regions and yearly are necessary in the future to enhance the predicting accuracy. |
