中文摘要 | Little is known about the role of tree sprouting in the regeneration of karst forest communities. In Shilin Stone Forest Geographical Park, southwestern China, all genets with the largest stem ⩾3 cm DBH (diameter at breast height) and/or stumps ⩾3 cm BD (basal diameter) were identified and number of sprouts counted in 10 transects (10 m × 100 m) in each of three evergreen broadleaved forest stands representing three regeneration stages (about 10, 20, and 30 years old). Species with >10 genets accounted for 72.4% of the 76 species, and all of them showed evidence of sprouting. One-third to two-thirds of the genets in the three forests were sprouting, with an average of 4.0–5.7 sprouts per sprouting genet. Sprouting capability (sprouting genets/total genets) and intensity (sprouts per sprouting genet) differed significantly among the three forest stages. More than 90% of the damaged genets were sprouting. The number of sprouts in a non-damaged genet was determined by intrinsic sprouting ability, and the number of sprouts in damaged genets was determined by stump size. As the forest developed, percentage of damaged genets increased, the portion of shoots ⩾3 cm DBH co-existing in a genet decreased, and the portion of shoots <3 cm DBH sprouted from damaged genet increased. Thus the role of sprouting changed from contributing recruitment in the young stage to persistence in the later stage. |
