“…This decrease was primarily due to the increased proportion of flowering culms that did not have leaves. Phyllostachys bamboo species resorb nutrients from senescing leaves before shedding; in our results, N, P, and K concentrations in senesced leaves of the flowering ramets were 35%–66% lower than those in green leaves of the non‐flowering ramets (Figure 3b–d and Table S1; even higher values were found by Umemura & Takenaka, 2014: 87%–92% of P and 86%–92% of K in P. edulis ), which suggests that these resorbed resources were likely translocated to the flowers. On the other hand, the amount of C in the culms and branches per unit stand, which was almost proportional to the amount of the biomass of the culms and branches per unit stand, was similar before and after the mass flowering (Figure 4a) because the major components of C are structural materials, including cellulose, which might not move during flowering events.…”

Phyllostachys nigra var. henonis (Poales: Poaceae) is a tall, temperate bamboo species that has a long monocarpic life history with a flowering interval of around 120 years that is often conspicuously synchronized across a wide geographical area.Interestingly, observations of the last major flowering event, which was about a century ago, suggested that mature seeds were rarely produced as a consequence. As this bamboo has recently started flowering across Japan after a century of silence, we seek to understand its reproductive strategy by quantifying the following four issues: (1) flowering patterns within stands, (2) the presence or absence of mature seeds, (3) resource allocations to reproductive parts, and (4) asexual regrowth capacity after mass flowering. We conducted field surveys at five flowering bamboo

“…Additionally, the allelopathic compounds produced by moso bamboo may suppress the growth of understory or eliminate neighboring plants [12]. Previous research has reported the impact of bamboo invasion on ecosystem functioning, such as changing plant diversity [13,14], altering soil water content [9], decreasing soil trace elements [15], and changing microbial diversity [7,16,17]. In addition, composition of soil total organic C (TOC) may degrade with bamboo invasion [18].…”

Moso bamboo (Phyllostachys edulis) is one of the widely growing bamboo species in Asia. Because of its fast growth and aggressive rhizomes, it is reported to invade other forests and reduce the biodiversity of forest ecosystems. To determine the changes in soil nutrient conditions due to moso bamboo invasion, this research measured the difference in soil labile carbon (C) and nitrogen (N) contents in a Japanese cedar (Cryptomeria japonica) forest invaded by moso bamboo in central Taiwan. The content of soluble organic C (S b OC), measured by both KCl and hot-water extraction methods, was lower in bamboo than cedar soils. This observation agreed with the finding that the more easily decomposed S b OC could be lost with bamboo invasion. In addition, both S b OC KCl and S b OC HW contents were positively correlated with microbial biomass C content, so the decreased labile organic C content in bamboo soils may reduce microbial biomass production. Principal component analysis revealed soil organic C content (total organic C, S b OC and acid-hydrolysable C) as the most important soil parameter affected by the bamboo invasion, followed by microbial biomass N and NO 3 − contents in soils. The soil quality index model also agreed with the degraded soil quality with bamboo invasion. In conclusion, the invasion of moso bamboo reduced the C and N pools in bamboo soil and degraded the overall soil quality.

“…Our study found that there was no difference in the reabsorption efficiency of P between SC and CK, but P resorption efficiency in RB was significantly higher than in CK in February and June 2020 (Table 2). Previous reports have also discussed different trends in seasonal variation, showing that P translocates from the leaves to other organs (Umemura and Takenaka, 2014). Potassium accumulates in meristems and young tissues, and is assimilated to the roots of higher plants (White, 2012).…”

“…Potassium accumulates in meristems and young tissues, and is assimilated to the roots of higher plants (White, 2012). Umemura and Takenaka (2014) investigated K loss from the leaves and observed K resorption from mature leaves to growing organs. In our study, K showed the highest resorption efficiency (Table 2), due to the retranslocation of K. Additionally, the leaching of rainfall also has a great influence on K loss.…”

Dynamics of Leaf-Litter Biomass, Nutrient Resorption Efficiency and Decomposition in a Moso Bamboo Forest After Strip Clearcutting

Strip clearcutting can significantly reduce the harvesting costs of moso bamboo forests. Although bamboo is characterized by rapid accumulation of biomass, it is still a concern that this management method may reduce long-term productivity. Nutrient cycling has long been considered essential for forests to maintain high primary productivity. However, nutrient cycling of bamboo forests after strip cutting has not been previously reported. We conducted a strip clearcutting experiment and surveyed the litter dynamics for 1 year. We assessed changes in litter nutrients in response to the cutting and calculated the nutrient resorption efficiency and litter decomposition rate to evaluate the effect on nutrient use efficiency and nutrient return. Our results showed that strip cutting had no significant effect on litter production and nutrient return in the moso bamboo forest (p > 0.05). However, annual litter biomass and nutrient return in reserved belts (RB) were significantly higher than those in the control (CK) (p < 0.05). P and K resorption efficiencies in RB were significantly higher than in CK during certain periods of bamboo growth (p < 0.05). We also observed that the annual decay constant of CK was significantly higher than that of plots that were strip clearcut (SC) (p < 0.05). Our results suggest that strip cutting does not affect nutrient use efficiency or storage in the short term.
