１９９７～１９９８年，在长沙的天水田和旱地比较研究了几种栽培因素对巴西陆稻ＩＡＰＡＲ９的穗粒结构和米质的影响。结果表明，土壤质地、土壤保水力、叶面肥、多效唑等会影响ＩＡＰＡＲ９的穗重和米质。巴西陆稻可作为育种资源加以利用和在缺粮少田地区的天水田和旱地作早、中稻栽培。
From 1997 to 1998, the effects of several cultural factors on the spike-grain structure and grain quality of Brazilian upland rice IAPAR9 were studied in Tianshui and dry land in Changsha. The results showed that soil texture, soil water retention, foliar fertilizer and paclobutrazol could affect the panicle weight and grain quality of IAPAR9. Brazilian Upland rice can be used as a breeding resource and cultivated in early and middle-season in the Tianshui and dry land in the area where the grain is scarce.
