“聪明”种子背后的科技密码
Xin Lang Cai Jing· 2026-01-05 18:44
马铃薯组培实验室中,科研人员检查脱毒苗生长情况。本报记者 祁万强 摄 本报记者 祁万强 王伟才 当脱毒马铃薯的第一株嫩苗,在凝胶培养基上伸展叶片后,科技云端解码作物基因密码的序幕便正式拉开。一粒"聪明"种子诞生的背后,是科研工作者 对"藏粮于技"的深情诠释,"云端大脑"让高原千年农耕文明在科技赋能下焕发新生。 冬日的阳光透过窗户,在马铃薯组培实验室内映射出点点光斑。一排排智能培养架上,凝胶培养基中脱毒苗在精准控制的光照与温度下茁壮成长。 然而,不是所有的脱毒试管苗都能成活,因此每一次的突破都凝聚着科研人员的心血。 这些先进的仪器和专注的面孔背后,是一场关乎未来的革命。 "马铃薯是无性繁殖作物,病毒会在薯块中代代累积,导致品种退化、产量锐减。"青海大学农林科学院副院长王舰拿起一株试管苗说:"我们的工作,就是 从优质薯种的茎尖剥离生长点,培育出健康的脱毒薯苗。" 这仅仅是万里长征的第一步。生长旺盛的脱毒苗通过"茎段快繁"技术获得成功后,被移栽到温室大棚中生产出原原种(微型薯),再经过一代代扩繁,才能 得到供给大田种植的优质脱毒种薯。 实验室里的"生命重塑" 推开青海大学农林科学院马铃薯接种室的隔离门,一股无菌空气 ...
