氮 (N)添加如何通过根际微环境调控提升植物磷 (P)富集能力？最新研究以超富集植物水蓼 (Polygonum hydropiper)为模型，发现100 mg N kg?1 处理显著激活根际磷库：钙氯提取态磷 (CaCl 2 -P)增加23%，微生物量磷 (MBP)提升1.8倍，同时酸性磷酸酶活性激增67%。 深层机制揭示，氮输入重塑了微生物"社交网络"——细菌 ...

Polygonum hydropiper Uses China: stems and leaves eaten. Malaya: young leaves used as flavoring. Australia (North Queensland, Flinders River): stalk roasted, then peeled and eaten.

Water pepper (formerly known as Polygonum hydropiper) is a summer annual that is often found growing in pastures, especially along streams and other wet places. The foliage is quite acrid, which is ...

This study compares individual phenotypic plasticity for components of fitness in four congeneric annual plant species with contrasting ecological distributions (Polygonum cespitosum, P. hydropiper, P ...

•Here we examined species differences in perception and response to two distinct types of shade cue, reduced photosynthetically active radiation (PAR) with and without reduced red: far red ratio (R: ...

For example, drought-stressed Polygonum hydropiper, a knotweed, passes on its stress response to seedlings, which become smaller, with slower-growing roots – even if they are grown in a drought ...
