British Columbia Fir

Pseudotsuga menziesii

Pseudotsuga menziesii，又称道格拉斯冷杉，是一种原产于北美洲西海岸的针叶树。尽管传统上被土著人民用于各种用途如建筑和医学，但文献中没有记录特定的传统用途。科学上表明，在陡峭斜坡上的 Ultisol 土壤上进行机械伐木与手工伐木相比，在两年内对土壤的影响并不显著。此外，研究还提供了 Morchellaceae 家族从地上生长到地下生长的单一过渡证据，并直接证明了 Leucangium 种类和 Pseudotsuga menziesii 之间的外生菌根共生关系。Douglas冷杉胚乳细胞悬浮培养产生了类似于传粉液中发现的分泌蛋白，这为研究胚乳蛋白质提供了一种潜在的方法。切除通常增加了枝条的水分势，但在大多数物种中减少了叶片气体交换，尽管效果因植物类型和特征而异。Pseudotsuga menziesii 没有记录到重大安全问题或药物相互作用。

科学怎么说

  • 这项研究发现，在陡峭的斜坡上使用带有牵引辅助装置的伐木机与手工伐木在Ultisol土壤上的影响在两年期内没有更负面的影响。 D PMID
  • 研究发现证据支持莫尔切丽科属中从地表生长到地下生长的单一过渡，并提供了与莱乌卡吉乌姆属物种和潘塞杜加·门济斯伊属之间外生菌根共生关系的直接证据。 D PMID
  • Douglas‑fir 树种的细胞悬浮培养物产生了与授粉液中发现的类似的分泌蛋白，提示这是一个可操作的系统，用于研究核质蛋白。 D PMID
  • 修剪通常增加了枝条的水势，但减少了大多数物种叶片的气体交换，尽管效果因植物类型和特性而异。 A PMID
