1987年和1988年，在阿肯色州斯图加特的非竞争性田间条件下，比较了红米（strawhull）、“Lemont”和“Newbonnet”水稻的生长和发育。 红米与普通水稻的生长发育差异大于水稻品种间的差异。 红米比水稻高，产生更多的秆m-2和地上干重，有较高的叶面积指数，并有较大的剑叶面积。 此外，它在季节后期具有较低的叶茎比，在季节早期具有较高的作物生长率，但在季节后期较低，并且产生的粒重低于水稻。 与Newbonnet相比，Lemont植物在出苗后60 d或更晚时较短，产生更多的秆m-2，具有更大的叶面积指数，并产生比Newbonnet更高的粒重。 此外，Lemont和Newbonnet产生了可比的叶茎比，作物生长速度和旗叶面积。
Growth and development of red rice (strawhull) and 'Lemont' and 'Newbonnet' rice were compared in 1987 and 1988 under noncompetitive field conditions at Stuttgart, AR. Growth and developmental differences were greater between red rice and rice than between rice cultivars. Compared to rice, red rice was taller, produced more culms m-2 and aboveground dry weight, had higher leaf area indices, and had a greater flag leaf area. Also, it had lower leaf to stem ratios late in the season, had greater crop growth rate early in the season but less late in the season, and produced a lower grain weight than rice. Compared to Newbonnet, Lemont plants were shorter at 60 d after emergence or later, produced more culms m-2, had a greater leaf area index, and produced higher grain weight than Newbonnet. Also, Lemont and Newbonnet produced comparable leaf to stem ratios, crop growth rates, and flag leaf areas.
