澳大利亚珀斯Kings Park的保护科学家在拯救极危物种示巴女王兰花免于灭绝的工作中取得突破性进展。[1]通过体细胞胚胎发生克隆技术，研究人员从单一种子成功培育出超过1000株植株，其中首株克隆兰花已在三年多时间内绽放花朵。[1]这一成就意义重大，因为该物种在野生环境中已所剩无几，仅存不足30株。[1]
克隆培育的兰花展现出明显优势。[1]与传统种植方法相比，克隆植株的开花速度约快一倍，花期仅需常规方法的一半时间。[1]更为显著的是，克隆培育的植株球茎大小是常规方法培育植株的十倍，使整体生长更加强健。[1]研究人员表示，"从一粒真正很小的种子，我们可以生成尽可能多的植株"。[1]
这项技术的潜力远超该物种本身。[1]保护科学家计划将该克隆技术推广应用于其他44种濒危兰花物种。[1]不过在将克隆植株回归野生前，研究团队强调还需进行更深入的研究，特别是关于传粉者和共生真菌的相关工作。[1]
Conservation scientists at Kings Park in Perth, Australia, have achieved a significant breakthrough in efforts to save the critically endangered Queen of Sheba orchid from extinction using somatic embryogenesis cloning technology.[1] From a single seed, researchers have generated more than 1,000 plant specimens through this advanced technique.[1] The first orchid successfully cultivated using this method has now flowered, reaching maturity in just over three years—half the time required by conventional propagation methods.[1]
The wild population of this rare species numbers fewer than 30 individuals, making the conservation initiative particularly urgent.[1] The cloned plants demonstrate superior vigor compared to those produced through traditional methods, with bulb size reaching ten times larger than conventionally propagated specimens.[1] As Digby Growns noted, the technique enables researchers to "generate as many plants as we can from a truly very small seed."[1] The successful flowering of the first cloned specimen validates the approach's potential for species recovery.
This cloning methodology will be applied to 44 additional endangered orchid species, significantly expanding the conservation toolkit available to botanists.[1] However, before reintroducing cloned plants to the wild, researchers must conduct further studies on pollinators and fungal relationships, according to Belinda Davis.[1]
