Snow roots are a very special type of roots that counteract geotropism to grow upward into long-lasting snow fields. They develop under snow at near 0ºC, a phenomenon that had previously only been reported from plant shoots (Körner et al. 2019). Up to now, this intriguing and spectacular looking plant structure has been discovered and studied in only a single species, i.e. the vernal forb, Corydalis conorhiza Ledeb. (poppy family, Papaveraceae) at an elevation of almost 3 km in the mountains of the northern Caucasus, Russia by Onipchenko et al. (2009a, 2014), who reported results from a snow-field labeling experiment with the natural nitrogen (N) isotope 15 N, accompanied with anatomical and structural root trait measurements.

雪根：它们在哪里，它们有什么用途？

雪根是一种非常特殊的根，可以抵消地向性以向上生长成持久的雪原。它们在接近 0ºC 的雪下发育，这种现象以前仅从植物芽中报道过（Körner 等人，2019 年）。到目前为止，这种引人入胜且外观壮观的植物结构仅在单一物种中被发现和研究，即春季异叶植物 Corydalis conorhiza Ledeb。（罂粟科，罂粟科）在俄罗斯北高加索山脉海拔近 3 公里处，作者是 Onipchenko 等人。(2009a, 2014)，他报告了使用天然氮 (N) 同位素 15 N 进行的雪场标记实验的结果，并进行了解剖学和结构根特征测量。
