在平均气温下，对4个珍珠谷子品种的叶面积发育、光截获和干物质生产进行了研究。19.5、21.0、26.0和31.0℃时生长最慢，31.0℃时生长最快。不同品种的冠层透光系数差异较大，SANIO为0.47，OASIS为0.23，平均能量转换效率为1.0~2.7g/MJ。这些品种在这些方面的排名与以前报道的萌发和早期建立的品种一致
Leaf area development, light interception and DM production of 4 contrasting pearl millet [P. americanum] cultivars were investigated at mean air temp. of 19.5, 21.0, 26.0 and 31.0°C. Growth was slowest at 19.5° and fastest at 31.0°. The canopies of the cultivars varied considerably with regard to their light transmission coeff., from 0.47 for Sanio to 0.23 for Oasis, and in their mean efficiency of energy conversion, from 1.0 to 2.7 g/MJ. The ranking of the cultivars in these respects was consistent with those previously reported for germination and early establishment
