以1年生杂交杨树无性系为试验材料，在生长季结束后对茎、皮、根等器官的生物量及热值进行研究。结果表明：共有13个杨树无性系的生物量高于平均值，无性系208的地上部分、地下部分和生物量均为最高，分别达到485.77、146.18、631.95 g；不同器官间干质量热值的顺序为茎、皮、根。不同杨树无性系的单株干质量热值存在极显著差异，其变异幅度为18.659~19.141 kJ/g。选出的优良无性系单株热值、生物量和单株干质量热值平均值分别比群体平均值高26.12%、25.99%和0.12%。不同无性系单株热值的差异主要来源于生物量。
Abstract
In this paper, biomass production and calorific values of components for oneyearold hybrid poplar clones were studied after one growth season. The results showed that the biomass production in 13 poplar clones were higher than population mean, and clones 208 had the highest biomass production in aboveground, underground and total, reached 485.77g, 146.18g and 631.95 g. Gross calorific values of components were also different, it was ordered as stem, bark, root. There were significant difference in seedling individual gross calorific values among all poplar clones, and the variation ranges were 18.659—19.141 kJ/g. The means of individual calorific values, biomass production and individual gross calorific values for poplar clones that were selected as elite clones were 26.12%, 25.99% and 0.12% higher than the population mean. The differences of individual calorific values for poplar clones were mainly determined by their biomass production.
