关于西瓜的这些谣言都是错误哒!

The False Watermelon Fact You Always Thought Was True

There are a lot of dubious claims floating around the Internet,
互联网上流传着许多可疑的说法
even about something as innocuous as watermelon.
甚至连西瓜这种无害的东西都有各种流言
Have you heard the rumor that
你听说过这样的谣言吗
if you cut into a watermelon and discover the flesh has a
如果你切开一个西瓜 发现它的果肉中间
crack in the middle,
有一条裂缝
you’ve got to toss it out because it’s full of harmful chemicals?
你必须扔掉它 因为里面全是有害的化学物质
It’s not true!
这不是真的!
First, let’s begin with where this rumor got its start:
首先 我们从谣言的源头说起:
Back in 2011, reports of exploding
早在2011年 中国西瓜爆炸的报道
watermelons in China hit the news.
就成了新闻焦点
The cause, it was discovered,
研究发现 其原因是
was impatient farmers overdosing their crops with a growth
缺乏耐心的农民用一种叫作氯吡脲的生长调节剂
accelerator called forchlorfenuron.
给他们的作物过量施肥
The chemical, combined with wet weather,
这种化学物质 再加上潮湿的天气
put those melons into overdrive,
让这些西瓜超速生长
and suddenly,those impatient farmers had nothing but acre after acre
突然之间 那些没耐心的农民手上除了一亩亩爆炸的西瓜
of burst fruit on their hands.
就什么也没有了
At the time, CBS News said that an investigative report
当时 哥伦比亚广播公司表示
by China Central Television emphasized, quote,
中国中央电视台的一篇调查报道强调
how farmers in China are abusing both legal and illegal chemicals –
中国农民是如何滥用合法和非法化学品的——
forchlorfenuron being a legal chemical in the country.
氯吡脲在中国是合法的化学品
And it turns out forchlorfenuron is legal in the U.S., too,
氯吡脲在美国也是合法的
but not for use in watermelons.
但是不能用在西瓜上
According to Snopes, the plant growth regulator was approved
据Snopes称 这种植物生长调节剂
for use on kiwifruit and grapes
在2004年被批准 可以用于猕猴桃和葡萄上
in 2004 and is applied only once.
并且只能使用一次
Per the EPA pesticide fact sheet,
根据美国环保署的杀虫剂说明书
forchlorfenuron improves fruit size, fruit set,
氯吡脲可以促进水果膨大 提高坐果率
cluster weight and cold storag in those fruits.
每串的重量和并利于冷藏
So, it makes some sense as to why Chinese farmers hoping for
因此 中国农民会使用这种化学物质是有一定理由的
massive melons in a hurry would use the chemical,
他们希望能在短时间内种出大量的西瓜
but it’s not being used in watermelons in the U.S.
但美国的西瓜却没有使用这种化学物质
So what does exploding fruit caused by misuse
那么 亚洲滥用氯吡脲
of forchlorfenuron in Asia have to do with
导致的水果爆炸与西瓜的裂缝
those cracks in watermelons?
有什么关系呢?
Well, the belief is that if the flesh
好吧 人们相信
of your melon has a crack, it’s an indicator that
如果瓜瓤有裂缝 就说明
the growth accelerator has been used,
使用了生长调节剂
causing it to grow too quickly to even keep up with itself,
使得瓜瓤生长过快 甚至跟不上瓜自身的生长速度
resulting in that internal fissure.
导致瓜瓤内部出现裂缝
Maybe that would be true if you were buying your watermelons in China, but here in the U.S.,
如果你在中国买西瓜 也许这是真的 但这是在美国
it’s likely there’s a far less nefarious reason for that rupture.
这种破裂很有可能有一个不那么糟糕的原因
Cracks in the flesh
西瓜果肉上的裂缝
of watermelons that aren’t pumped full of forchlorfenuron are actually
如果没有充满氯吡脲的话
caused by hollow heart disorder, and it’s nothing to fear.
实际上是由空心病引起的 没什么好害怕的
Though hollow heart in watermelons was once believed to be caused
尽管西瓜的空心病曾被认为快速增长的
by rapid growth due to excess nitrogen, over-watering,
原因是过量的氮 过度浇水
and favorable growing conditions that prompted the rind
和有利的生长条件使得瓜皮
to expand faster than the flesh inside,
比里面的肉膨胀得更快导致的
A 2014 study by University of Delaware assistant
2014年 特拉华大学助理教授
professor Gordon Johnson showed that the fruit’s distance
戈登•约翰逊的一项研究表明 罪魁祸首实际上是
from its pollen source is actually to blame.
果实与花粉来源的距离
Watermelons that were further from their pollinizers had a higher likelihood of hollow heart,
远离授粉者的西瓜更有可能出现空心
and bad weather early in the growing season only increased that risk.
而生长季节前期的恶劣天气只会增加这种风险
Johnson explained,
约翰逊解释说
“Hollow heart occurs in poor weather conditions,
空心病的症状出现在恶劣的天气条件下
and oftentimes in the early watermelons.
往往出现在早期西瓜上
That’s because we’re more likely to
这是因为 遇到寒冷的夜晚
have cold nights or stormy conditions, particularly
或暴风雨天气 尤其是在寒冷的夜晚
cold nights, where those early flowers are the most affected.”
这些早期的花朵最受影响
“With inadequate pollination”, Johnson continued,
约翰逊继续说 由于授粉不足
” there is reduced release of the plant hormone
控制贮藏组织发育的
that controls the development of storage tissue leading to hollow heart.”
植物激素的释放减少 从而导致空心
And since there isn’t a quick fix for hollow heart disorder,
而且 由于治疗空心病没有类似杀虫剂或化肥这种
like pesticides or fertilizers,
快速治疗植物疾病的方法
chances are good that you’ll cut into a watermelon
在一年中的某个时候
with hollow heart at some point during the year,
尤其是在那些西瓜早熟的季节
especially in those early season melons.
你很有可能会切到一个空心病的西瓜
Bottom line
总而言之
Watermelons with hollow heart might not make for the prettiest slices,
空心西瓜可能切不出最漂亮的西瓜片
and you might not get the ideal Instagram-worthy shot out of one,
你也可能拍不出最适合上ins的西瓜照片
but according to Gardening Know How,
但是根据园艺知识
they’re perfectly safe to eat.
它们完全可以放心食用
That’s because hollow heart isn’t actually a disease of the fruit,
因为空心事实上并不是水果的一种疾病
but a” failure in the seed production process”,
而是一次发育过程的失败
and it’s actually this failure and the concentration of sugar it causes that,
实际上 正是这种失败和糖分的集中
some say, makes the flesh even sweeter.
有人说 这样会使果肉更甜
Almost makes you hope for a watermelon with hollow heart now, doesn’t it?
这是不是几乎让你希望有一个空心西瓜了?
