“…Variations in stand density and organic matter input in bamboo stands can represent important plant controls affecting below-ground processes and may be particularly relevant in bamboo-dominated communities that form dense monospecific stands and underground root networks (Fukuzawa et al, 2007;Yin et al, 2019). Unmanaged stands have higher densities than managed stands (Chen et al, 2016;Yin et al, 2019).…”

“…We selected 13 sites comprising managed and unmanaged stands distributed along a broad climatic and latitudinal gradient (spanning 23 • N to 33 • N) across southern Japan and Taiwan. Because the culm density of Moso bamboo varies depending on the management conditions (managed stands maintain densities of less than 4,000 culm ha −1 , whereas abandoned stands exceed densities of 8,000 culm ha −1 ) (Inoue et al, 2018;Yin et al, 2019), we also considered the variation in stand properties and input of organic matter as potential drivers of decomposition. To avoid variation in litter quality and the possible influence of home-field advantage from local litter, we used the TBI method (Keuskamp et al, 2013) to estimate the decomposition parameters k and S as proxies for the initial decomposition rate and long-term carbon accumulation, respectively.…”

Moso bamboo (Phyllostachys edulis) is currently distributed across a wide geographical area in East Asia. As a common bamboo species occurring along a broad environmental gradient, there is a need to understand how environmental and biotic drivers affect belowground processes at large scales. In this study, we investigated the influence of climate, soil properties, stand characteristics, and organic matter input parameters as potential drivers of the initial decomposition process in Moso bamboo stands at a regional scale. Using the Tea Bag Index method, we estimated the initial decomposition rate (k) and stabilization factor (S; potential long-term carbon storage) from standard litter incubated at 13 sites across southern Japan and Taiwan. We found that both decomposition parameters were strongly affected by the climate. The climatic conditions during the incubation period better explained the variance in k. In contrast, the long-term climate was more important for S. Notably, temperature and precipitation interactively affected the initial decomposition rates. This interaction showed that in warmer sites, precipitation increased k, whereas in cooler sites, precipitation had no effect or even decreased k. Soil parameters had no influence on k and only had minor effects on S. A structural equation model showed that the stabilization factor was indirectly affected by stand density, which suggests that higher bamboo densities could increase litter stabilization by increasing above-and below-ground organic matter input. Our study highlights the central role of climate in controlling decomposition processes in Moso bamboo stands on a broad scale. Moreover, differences in stand structure can indirectly affect potential soil carbon storage through changes in organic matter input and soil conditions.

“…However, the rapid expansion of moso bamboo forest has posed a huge threat to the adjacent ecosystem and biological resources, leading to the loss of species diversity 10 , 11 , the destruction of native forest ecosystems 12 , 13 , the difficulty of natural regeneration 14 , 15 and the stagnation of community succession 5 , 16 . In addition, the phenomenon of abandonment caused by the decrease of the bamboo shoot price and timber price and the increase of the labor costs reduced the enthusiasm of bamboo farmers for management 7 , 17 , which resulted in the expansion of moso bamboo to adjacent systems due to the fierce internal competition. Therefore, moso bamboo forest is considered to be invasive and has resulted in intense forest expansion 17 , 18 .…”

“…Cai et al put forward the method of “digging pit and irrigating water” to restrain the expansion of moso bamboo based on the growth characteristics of rhizome 19 . Suzuki and Nakagoshi proposed to increase the numbers of shoot harvesting and culm cutting to inhibit bamboo expansion 17 . Although these management strategies were effective for bamboo control, it was difficult to be applied in practice due to the disadvantages of long cycle, high investment and slow effectiveness.…”

The objectives of this study were to investigate the allelopathic effects of sesame extracts of on seed germination of moso bamboo, and to isolate and identify the potential allelochemicals. A factorial design with three organs (root, stem and leaf) and five concentrations (0, 25, 50, 75 and 100 mg mL−1) was carried out. Seeds of moso bamboo were soaked in sesame extracts to investigate their germination and growth. The allelochemicals were isolated and identified using the high performance liquid chromatograph (HPLC) system. The germination indices of the same organ decreased with the increase of extract concentrations, while the mean germination time increased, picking at the concentration of 100 mg mL−1. The radicle length and plumule length decreased, while the ratio of radicle length to plumule length increased. The allelopathy inhibition effect increased with the increase of extract concentrations, and it was significantly higher at the concentration of 100 mg mL−1 than that of 25 mg mL−1. The synthesis effect increased with the increase of extract concentrations, and it was significantly higher in leaf than root and stem. Chemical analyses identified 9 allelochemicals species (mostly phenolics and alkaloids) in the aqueous extracts. These results indicated that aqueous extracts of sesame caused the delay in seed germination and growth of moso bamboo, and phenolics and alkaloids in the aqueous extracts maybe the major reasons for the observed inhibition effects of sesame.
