PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1733-1745, September 2026.Asian elephants play crucial roles in ecosystem functioning, and their interactions with plants influence above‐ and belowground carbon cycling. We tested whether their mechanically destructive foraging triggers short‐term, stress‐induced shifts in tree root exudation, an underappreciated pathway linking herbivory to belowground carbon processes.

Shuitu Baochi Xuebao, 2017 为探讨草本植物根系对崩岗洪积扇土壤抗剪强度的影响，以巨菌草（Pennisetum sp.）和宽叶雀稗（Paspalum wettsteinii）为研究对象，采用WinRHIZO根系分析系统对根系特征进行定量分析，并采用原位剪切试验测定崩岗洪积扇各土层的抗剪强度。结果表明：（1）根系能够改善土壤的结构及水分状况。（2）2种草本植物根系均主要分布在0—5 cm土层，该层巨菌草根系各参数值是该草种根系均值的3.1~4.39倍，宽叶雀稗的则为2.23~2.57倍；随着土层深度的增加，巨菌草根系参数呈对数函数减小，

, 2016 水分再分配作用主要是指根际区不同部位土壤间与植物根系间水势差下的运移过程。夜间弱蒸腾作用下，具有水分再分配作用的根系能够从湿润土层中吸收水分，而后将水分运输并释放至干燥土壤层中，使干燥土层的水分有效性得到改善。水分再分配作用提升的这部分水除用于植物本身的需求之外，也可为相邻植物所共享。通过这种水分调节方式能够有效缓解植物的干旱胁迫。本研究通过调控夜间植物蒸腾，以控制植物根系内水分再分配发生的条件，利用上下分根方法及根系观测技术，设置控制处理（仅接受白天自然光照），夜间光照处理（接受24小时光照 ...

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1675-1691, September 2026.Banana and plantain are vital for food security and income in West Africa, yet banana bunchy top virus (BBTV) threatens production. This study combined remote sensing, field surveys, modelling and socio‐economic analysis to assess BBTV spread and control strategies in Benin.

Harvesting of two alpine Artemisia: Effects of an amateur practice on wild plant dynamics
PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1817-1828, September 2026.Wild plants are consumed all over the world, and knowledge of the effects of harvesting is necessary to ensure the sustainability of this activity. Our 3‐year study of two closely related alpine Artemisia species in the Southern Alps revealed a positive impact of harvesting at the plant scale and on the short term.

Shuitu Baochi Xuebao, 2021 为明确滇南地区普洱茶种植下土壤优先路径特征以及根系对其形成的影响，以典型普洱茶产地为研究对象，灌草地为对照，基于染色示踪法与图像处理技术，定量分析普洱茶树根系特征与土壤优先路径的关系，解释根系对优先路径形成的影响。结果表明：（1）茶地和灌草地染色路径宽度随土层深度增加呈不同幅度的下降趋势，茶地优先路径的连通性比灌草地差，优先路径的发育程度小于灌草地；（2）根系主要集中分布在土壤表层，随土层深度增加，根重密度、不同径级根长密度均呈减小趋势，径级≤1 mm的根长密度贡献度最大，达到84.08%；（3 ...

, 2007 在水培条件下,针对梭梭、囊果碱蓬和钠猪毛菜3种荒漠盐生植物,研究它们苗期在不同盐浓度条件下根系和根毛形态的差异。结果表明一定浓度的盐分可以促进3种盐生植物生长,但较高浓度的盐抑制其生长,特别是对根系生长的抑制作用更大。在同样盐浓度下,钠猪毛菜的生长最快,生物量也最大。在盐分浓度较低时,3种盐生植物的主根长和总根长都有所增加,与对照相比,囊果碱蓬增加的幅度较大,但高浓度的盐会抑制根系总长度的增加,其中囊果碱蓬较梭梭和钠猪毛菜抑制的程度轻。盐分对3种植物的根系平均直径没有显著的影响,但有减小的趋势 ...

Diverse Prairie Mixtures Stabilize Biomass Yields for Sustainable Aviation Fuel Production
PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1829-1838, September 2026.Meeting global demand for sustainable aviation fuel will require the additional production of vast quantities of plant biomass, which does not compete with food production or degrade sensitive ecosystems. Our multisite experiment shows that sowing diverse native prairie seed mixes—and managing them without intensive inputs—yields a more reliable ...
