Black Cottonwood
Populus nigra
Populus nigra，通常称为黑杨树，在欧洲和亚洲是传统树木。尽管其在传统医学中的使用尚未广泛记录，但研究表明它具有某些生物学活性。当温度约为40°C时，Populus nigra会独立于净光合作用释放异戊二烯，虽然这一发现的意义尚不明确。蜜蜂蜂巢中的蜂胶含有苯基咖啡酸酯和肉桂酸苯乙酯等化合物，这些化合物已被证明可以保护人类骨骼肌细胞免受过氧化氢引起的氧化损伤。此外，Populus nigra的芽提取物显示出与欧洲蜂胶相似的组成，并表现出抗氧化和抗生物膜特性。然而，干旱和热应激单独都降低了Populus nigra幼苗的表现，而联合效应导致了更严重的生理功能障碍和生长抑制。

科学怎么说
- 干旱和热应激分别影响了Populus nigra幼苗的表现，而联合效应导致更严重的生理功能障碍和生长抑制。
- 在约40 °C温度下，欧洲黑杨中异戊二烯的排放与净光合作用脱钩。
- 研究发现，用于保护蜂巢的蜂蜜蜜蜂树脂中含有的化合物如苯基咖啡酸酯和咖啡酸苯乙酯可防止氢过氧化物诱导的人类骨骼肌细胞氧化损伤。
- 黑 populus 树芽提取物在组成上与欧洲蜂胶相似，并显示出抗氧化和抗生物膜活性。
- Populus nigra 在结合干旱和植食性处理下唯一诱导产生水杨酸，而不同物种的生长变化并不一致。
- 纳米聚苯乙烯影响了落叶和底栖藻类的营养价值，从而以浓度依赖性的方式影响河螺的摄食偏好。
- 研究发现，抗性Populus nigra杂交种QB3上调了与α-亚麻酸代谢相关的基因，并且在亚洲长角虫取食后，抗性杂交种Ta中的α-亚麻酸含量增加。
