人民日报:“抹避孕药培育无籽葡萄”纯属无稽之谈

2016-09-13 03:36:07   人民日报

原标题:“无籽葡萄抹避孕药”纯属无稽之谈(求证)

本报记者 蒋建科 史自强 胡安琪

时下正值吃葡萄的时节,但近日一段视频在微博、微信上大量传播,让不少人“望葡萄却步”。视频中,一位“果农”模样的男子一边搬运葡萄,一边和拍摄者对话,称无籽葡萄是“蘸了避孕药的”。随着视频转发传播,一些无籽葡萄产区被媒体曝出销售已受影响。无籽葡萄是怎么种出来的?真是蘸了避孕药所致吗?吃无籽葡萄会损害健康吗?人民日报“求证”栏目记者进行了走访调查。

抹避孕药能让葡萄无籽?

回应:受访果农从未听过这种做法;专家表示人用避孕药对植物不起作用

这段网传视频中,“果农”反复提到了“避孕药”,并回答拍摄者提问说,“无籽葡萄不敢给孩子吃”“吃了肯定有影响”。

在新浪微博上,名为“石家庄资讯通”的官方认证账号8月28日透露,这段视频的发生地是在石家庄附近的一家采摘园,来源是粉丝爆料,其家人在8月27日从采摘园的果农处获知该“内幕”。

记者9月11日与该微博运营者联系,询问视频中的采摘园在哪里,可否联系上爆料网友。该博主回复:“他拒绝接受采访。”而目前通过微博检索,8月27日网民“太阳蒙脸的面罩”最早在微博发布这一视频,该网民9月11日回复记者:视频系网友提供,“已经辟谣了,果农的说法不完全属实”。

为弄清真相,记者来到河北石家庄周边的几个主要葡萄产区。当地农民看了视频,表示视频中“果农”的口音像本地口音,但有待进一步确认。

在晋州市东里庄镇宿生村,葡萄种植大户李仓英表示,自己从未听说过抹避孕药能种出无籽葡萄来。记者向晋州的农技员和乡镇干部打听,他们也都表示没听过这种做法。

涂抹避孕药能产生无籽葡萄吗?

石家庄市妇产医院生殖医学中心二门诊主任亓蓉表示,避孕药只有在进入人体后才能被人的响应识别机制所识别,进而调节体内各项生理指标,达到降低受孕效果的目的。而植物体内缺乏相应的受体以及信号途径,作为动物激素的避孕药无法被植物识别和起效,也就根本无法给植物“避孕”。

“蘸避孕药的说法很荒谬。”中国农业科学院果树研究所、农业部果品质量安全风险评估实验室(兴城)主任聂继云说,植物用的生长调节剂俗称“植物激素”,与动物激素的分子结构完全不同,植物细胞与动物细胞的结构和携带的蛋白也完全不同。人用避孕药没法让水果无籽,植物激素也无法调节人的生长发育。
