“国产精品鲁一区二区”赣南山区新发现国产精品鲁一区二区濒危植物突托蜡梅野外最大种群

  中新国产精品鲁一区二区网南昌12月5日电 (记者国产精品鲁一区二区 姜涛)“这是目前这一濒危树种已知的野外最大种群。”上海辰山植物园、国家重要野生植物种质资源库辰山中心科研人员钟鑫5日向记者证实,他们团队近日在江西赣州市会昌县科考过程中发现并确认了逾万株野生突托蜡梅。

  突托蜡梅是江西赣州的特有濒危植物,于1984年在江西赣州安远县发现并发表,其分布范围十分狭窄,最初发现时仅有十余株,之后新的野生种群陆续在江西安远县、会昌县山区被发现。

  此次发现的该种群位于会昌县清溪乡,当地在过去走访调查中知道这一带有突托蜡梅野生种群,国产精品鲁一区二区但对其种群规模尚未调查清晰。经上海辰山植物园科研团队初步测量和踏查,确认该种群有突托蜡梅个体超1万株,是该物种目前已知的野外最大种群。

  2023年生态环境部发布的《中国生物多样性红色名录-高等植物卷(2020)》将其列为“濒危(EN)”。“列为濒危其实是基于多方面考虑,一是之前它的发现存量不是太多,再一个可能这个区域容易受到人为的破坏和干扰。”钟鑫补充道。

  此外,钟鑫现场观察分析认为,突托蜡梅开花量巨大而结实很少,这可能是因为进入冬季,传粉昆虫不活跃而导致的结实率低。“同时,突托蜡梅树下有很多刚萌发的幼苗,但稍大一点的苗就没了,可能是林下缺乏光照,小苗难以发育成株,这些都可能是导致其濒危的细节因素。”

  当地乡镇干部邓国清表示,接下来将采取多种方式对突托蜡梅进行宣传,并制定相应的村规民约,提高村民对突托蜡梅的认识,增强民众对这一珍稀濒危物种的保护意识。(完)
