Abstract

In order to understand the influence of truncation on canopy biomass accumulation, distribution and branch and leaf size of Dendrocalamus latiflorus, the modular biomass, biomass ratio, leaf area and dry weight, the size of branch biomass distribution ratio and the quantity of commodity leaves of D. latiflorus with different ages were measured and analyzed. The results showed that the aboveground modular biomass of D. latiflorus was in the order of stem>branch>leaf. The leaf biomass, leaf/branch biomass ratio and leaf/stem biomass ratio showed a trend of 2a > 3a > 1a. With the increase of age, the aboveground biomass, branch biomass, stem biomass branch/stem biomass ratio of D. latiflorus followed an increasing trend. The allocation proportion of branch biomass and leaf biomass of 2- and 3-year-old D. latiflorus were significantly higher than that of 1-year-old D. latiflorus, while the allocation proportion of stem biomass of 2- and 3-year-old D. latiflorus were significantly lower than that of 1-year-old D. latiflorus. In order to improve the spatial expansion capability to intercept more light resources, the D. latiflorus stand reduced the 0-8 mm branch biomass allocation, while increased the branch biomass input of the 8-16 mm, 16 mm or above. Truncation strongly affected the biomass distribution pattern, significantly reduced the branch, leaf, stem, and aboveground biomass. After truncating, the D. latiflorus stand increased the allocation proportion of branch biomass and leaf biomass, reduced the allocation proportion of stem biomass. At the same time, it improved the single leaf area and dry weight and increased the biomass allocation proportion of 8-16 mm, 16 mm or higher branch, reduced the biomass allocation proportion of 0-8 mm branch for the purpose of balancing the growth of branch and leaf, and improve the environmental suitability of truncated D. latiflorus. After D. latiflorus stand was truncated, the biomass ratio of leaf/branch, leaf/stem, and branch/stem increased, indicating that the biomass allocation inclined to the leaf and branch. Truncation reduced the picking height, the results showed that after D. latiflorus was truncated, the commodity leaf increased by 29.68% compared with the untruncated stand, the number of commodity leaf at the bottom of canopy increased by 79.73% and that in the middle of canopy increased by 25.81%. The change of the relationship between branch and leaf showed that truncation influenced the resource utilization strategy of D. latiflorus stands in the first growing seasons after truncating. However, further studies on change regulation with the age of truncation are needed.
