摘要
以山东省栽种的5个杨树无性系(I-107杨、L35杨、中菏1号,中林46杨和八里庄杨)为材料,在超短轮伐经营下,研究其生物量及分配规律。结果表明:不同杨树无性系间生物量差异达显著水平,杨树品系是影响超短轮伐经营生物量产出的重要因素,各无性系的1年生生物量分布为93.72g^432.82g,其中以L35的生物量最大,其次为I-107杨、中菏1号、中林46杨和八里庄杨。各杨树无性系不同植物组织间生物量分配比例也不同。
The biomass of five one--year--old poplar clones for short rotation management were studied. The results showed that： Poplar clones were a maior factor influencing biomass of the one year--old plantation, and there was a signifi- cant difference among five clones. The biomass measured was from 93.7 g to 432.8 g, among which P. ×euramericana cv. ＇79 35＇ showed best, and then they were P. Xeuramericanacv. ＇74/76＇, P. ×euramericanacv. ＇Zhonglin46＇, P. deltoites cv. ＇ Zhonyhe-- 1 ＇ and P.×＇ Balizhuangyang＇.
