对14个北美杂种白杨无性系在北京附近1 × 1 m短轮伐期人工林中的表现进行了评价。无性系间的生态生理和形态特征存在显着差异。DN-17、DN-2、DN-182、DN-14274、328-162和NM 6表现出较高的出苗率和存活率，DN-17、DN-14274、DN-182和NE-222表现出较短的生育期。其它无性系（306-45、195-522、184-411和328-162）生育期较长，可能更适合华南地区。克隆DN-2、DN-182和195-522具有最高的生产力和作为生物质生产者的最佳潜力。DN-14274、DN-17、DN-182、NE-222和DTAC-7无性系在第一生长季分配的地下生物量高于其他无性系，表明它们可能更适合于北方等干旱地区。克隆195-522、184-411、DTAC-7、NE-222、R-270和306-45具有较高的CO2同化能力。无性系NE-222、306-45、DTAC-7、195-522、R-270、15-29和DN-17具有较高的光合潜力，能够适应广泛的环境条件。无性系195-522、184-411、328-162、DN-182和NM 6具有较高的水分利用效率，表明它们能够更有效地利用土壤水分，尤其是在干旱季节和干旱地区。无性系R-270、DN-14274、15-29、DN-2和DTAC-7具有较高的蒸腾速率，表明它们在干旱季节和干旱地区需要频繁灌溉以确保正常存活和生长。
The performance of 14 North American hybrid poplar clones was evaluated near Beijing in short-rotation plantations grown at a 1 × 1 m spacing. Significant clonal differences were found in eco-physiological and morphological characteristics. Clones DN-17, DN-2, DN-182, DN-14274, 328-162, and NM6 exhibited high emergence and survival rates, and DN-17, DN-14274, DN-182 and NE-222 had a short growing period. Other clones (306-45, 195-522, 184-411 and 328-162) had a long growing period and may be more suitable in southern China. Clones DN-2, DN-182, and 195-522, had the highest productivity and the best potential as biomass producers. Clones DN-14274, DN-17, DN-182, NE-222, and DTAC-7 allocated more belowground biomass than the other clones during the first growing season, indicating that they might be better adapted to arid regions such as those in northern China. Clones 195-522, 184-411, DTAC-7, NE-222, R-270 and 306-45 had a higher capacity for CO2assimilation. Clones NE-222, 306-45, DTAC-7, 195-522, R-270, 15-29, and DN-17 had a higher photosynthetic potential and could potentially adapt to a wide range of environmental conditions. Clones 195-522, 184-411, 328-162, DN-182, and NM6 had higher water-use efficiency than the others, suggesting that they would utilize soil water more effectively, especially in the dry season and in arid regions. Clones R-270, DN-14274, 15-29, DN-2, and DTAC-7 had higher transpiration rates, indicating that they would require frequent irrigation in the dry season and in arid regions to ensure normal survival and growth.
