Abstract

This study was carried out to investigate above-ground biomass of white poplar (Populous alba L.) plantations by four different plant spacing (0.5 × 0.5, 1 × 1, 2 × 2 and 4 × 4 m) in south west of Iran. After taking inventory, 10 trees were selected from each density section at one-hectare area (totally 40 stems). The tree's characteristics including diameter at breast height (DBH), total height, and crown diameter were measured. Then measured trees were felled down in order to measure the wet and dry weight of their different organs. After sampling from all the parts, carbon stock in the structure of this biomass species was obtained and the results showed that the most amount of biomass among the components per hectare is related to the bole wood and most amounts of biomass was related to the 0.5 × 0.5 m and 1 × 1 m planting spaces.

10年杨树生物量和碳分配伊朗西南部的种植园

研究了伊朗西南部4种不同株距(0.5 × 0.5、1 × 1、2 × 2和4 × 4 m)条件下白杨人工林的地上生物量。清查后，在1公顷面积内每个密度段选择10棵树(共40株)。测定了树的胸径、总高、冠径等特征。然后将被测量的树木砍倒，以测量其不同器官的干湿重量。结果表明:每公顷各组分生物量中与孔材有关的生物量最多，与0.5 × 0.5 m和1 × 1 m种植空间有关的生物量最多;
