摘要

虽然生物多样性已被广泛证明能促进森林中的树木生长,但生物多样性在细胞水平上的影响仍不清楚。这阻碍了对多样性如何影响木材生产的深入理解。在这里,我们在细胞水平上研究了邻域组成对木材形成过程的影响。我们发现,群落多样性显著增加了生长季节产生的木质部纤维细胞的数量和壁厚,从而促进了生物量的增长。与单一栽培相比,最高邻域物种丰富度(NSR = 4)的木本生物量平均增加了19% ~ 29%。邻域多样性也导致形成层物候的变化。树木丰富度越高,形成层活动开始越早,壁增厚持续时间越长。此外,邻近竞争减少了血管面积,这与细胞壁厚度密切相关。我们的研究从微观角度研究了多样性和竞争对木材形成和木质生物量生产的影响。我们强调,当忽略细胞壁厚度的变化时,多样性对木质生物量积累的贡献可能被低估。

Positive Diversity Effect on Woody Biomass Production by Promoting Cell Number and Cell Wall Thickness.

While biodiversity has been widely shown to promote tree growth in forests, the effects of diversity at the cellular level remain unclear. This hinders a deeper understanding of how diversity influences wood production. Here, we investigated the influence of neighbourhood composition on wood formation processes at the cellular level. We found that neighbourhood diversity significantly increased both the number and wall thickness of xylem fibre cells generated during the growing season, resulting in enhanced biomass growth. Compared with monocultures, woody biomass production at the highest neighbourhood species richness (NSR = 4) increased by an average of 19%-29% across the studied species. Neighbourhood diversity also led to a shift in cambium phenology. An earlier start of cambium activity and an extended duration of wall thickening were observed under higher tree species richness. Furthermore, neighbourhood competition decreased vessel area, which was closely associated with cell wall thickness. Our study offers a microscopic perspective on the effects of diversity and competition on wood formation and woody biomass production. We highlight that the contribution of diversity to woody biomass accumulation may be underestimated when variation in cell wall thickness is ignored.
