[size=36.3222px]用毛吸雾提供水分一说我认为不合逻辑。。。我们都知道裸露的表皮在雾气中更容易形成一层水膜。。有利于表皮吸水。。。由此推论。。我认为恰恰相反。。。生长点处长浓密毛不是为了利于吸水。。而是为阻隔雾气防止生长点处表皮在夜间被水膜覆盖。。这样更有利于CAM植物在夜间生长点处表皮气孔保持开放。。。有利于气体交换。。并且密毛在白天还可以防止过强的紫外线光氧化生长点处叶绿体。。可以提高光合效率。。这个解释是不是更合乎逻辑作者: 大胆呆河马 时间: 2020-1-4 15:36
用百度搜索已经废止的仙人掌科植物属名是认真的吗？
Many species have been given both the name Neochilenia and Neoporteria at some time in the past. However, modern growers distinguish them in this way: Neochilenia have short to no spines and funnel shaped flowers that enable the inner part of the flower to be clearly seen when fully open. The floral tubes of Neochilenia are hairy and these later form hollow, fleshy fruits. In contrast, species in the Neoporteria group have denser, longer spines in general than Neochilenia. The flowers are bright pink with yellow interiors and are more of a tube shape as the inner petals remain mostly closed. The outer petals flare out and thus, the flower is not truly a tube shape as other cactus genera, but even when fully open, the inner parts of the flowers are still obscured by petals. The floral tubes may have a little fuzz and form similar fruits to the Neochilenia group. 作者: 老炮 时间: 2020-1-4 18:57
