“刚开始拒绝后来慢慢接受视频”四川发现一种刚开始拒绝后来慢慢接受视频新石斛

  中新刚开始拒绝后来慢慢接受视频网成都12月31日电 刚开始拒绝后来慢慢接受视频(记者 张浪)位于成都市青白江区的国际石斛研发中心31日对外透露,该中心科研人员在四川雅安发现了兰科石斛属新物种,并命名为“洪斌石斛”。相关研究成果于近日在国际植物分类学期刊《Phytotaxa》上发表。

  2020年以来,国家石斛林木种质资源库杨洪斌团队长期对四川石斛野外分布进行科学调查。2023年对四川雅安的一次石斛分布科学调查中,在海拔1000—1500米的森林岩石和山谷悬崖上发现,阔叶树干上生长有一种与石斛属植物相似的兰花品种,并判断这种兰花可能是一种新的类似细茎石斛的品种,因为它有短而稍细长的茎,开在无叶茎末端的白色小花,颏的长度超过芽的一半。

  杨洪斌团队联合中国林科院专家一起对发现的该种兰科石斛属进行形态学观察和分子研究。根据形态学研究及使用ITS、质体DNA和组合数据进行系统发育分析,研究人员确定了该种石斛是一个新物种,并以发现者杨洪斌命名为“洪斌石斛”。

  目前,雅安只有两个地方发现了2丛。这两个地点相距超过4公里。迄今为止,该石斛花的成熟个体数量不到10个,也没有关于其种群状况的进一步数据。

  据国家石斛林木种质资源库负责人杨洪斌介绍,中国是石斛利用大国,不是种源大国,全球分布了1500余种,中国仅有80余种。石斛自古以来就是中医文化的重要组成部分,该新物种的发现不仅为中国增加了石斛新物种,对石斛的科研保护开发利用也有重要意义。(完)
