 花朵变色:了解变色的原因

园林和花坛中常见的一些植物会因土壤酸碱度、光照强弱以及生化和生理机制等因素而发生花色变化,其中主要是花青素的表现。

值得注意的是,花色变化是被子植物中一种相对常见的现象,不应与伴随衰老过程出现的失色和变暗相混淆。 就功能而言,与花色变化相关的机制涉及三大类植物色素:类胡萝卜素、类黄酮和甜菜苷。

另一个与这种颜色变化有关的因素也是动物授粉者的存在,因为昆虫和动物从花朵中采集花粉和花蜜作为食物,然后移动到下一朵彩色花朵重复这一过程。 在它们从一株植物移动到另一株植物时,花粉会粘在它们的脚和身体上,将其中一些花粉传播到其他花朵上,促进授粉和传粉。因此,人们相信,随着时间的推移,花朵会不断进化其特性,以更好地吸引鸟类、蜜蜂和其他授粉者。

3种会变色的花卉

正如我们所看到的,有几种因素能够刺激花朵的颜色变化,无论是生理的、自然的还是环境的因素,这使得种植者可以对它们进行不同的管理,以获得特定的颜色。 因此,了解这三种花朵会变色的品种。

  1. 兰花树

树兰,学名Bauhnia monandra,是一种花朵颜色会发生程序性变化的品种。 当植株幼小时,它的颜色是白色的,其亮点是中央花瓣上的红色斑点。 然而,随着它的生长发育,这个单一的斑点花瓣会弯曲,并将其他结构染成粉红色,使花瓣的颜色标准化。

  1. 绣球花

绣球花因具有这种特性而闻名。 在这种情况下,花色的变化是由土壤的pH值变化引起的,花色在蓝色、紫色和粉色之间变化。 蓝色花瓣出现在酸性基质中,粉色花瓣出现在碱性土壤中。 紫色花瓣处于两种颜色之间,出现在中性pH值的基质中。 因此,要做好养护工作。pH值,或者如果您想换一种颜色,也可以改变pH值。

  1. 坎布拉

坎芭拉的颜色变化是生理性的,随着时间的推移而发生变化。 该品种在春季开花,最初是黄色,然后是橙色,直至红色。 因此,在同一朵花中,可以发现三种色调的花瓣。
