生长最快的植物

The Fastest-Growing Plant In The World

Hi, this is Julián from MinuteEarth.
嗨 我是《分钟地球》的Julián
Bamboo can grow as fast as three feet per day!
竹子竟然一天可以长三英尺!
In fact, when it comes to upward growth, bamboo is the fastest growing plant on Earth,
事实上 竹子是向上生长最快的植物
able to shoot up as tall as a 10 story building in just 8 weeks,
它能在短短八周内暴长到十层楼高
giving pandas a new meaning to the term “fast food.”
熊猫吃的可真是别具特色的“快餐”
The key to this absurdly fast growth
这般极速生长的秘诀在于
is that despite its bamboozling height and sturdiness,
尽管竹子高大挺拔 质地坚硬
bamboo isn’t a tree – it’s a very special grass.
但它不是树 而是极为特殊的一种草
Yup, that’s right, bamboo, along with wheat, rice and other grasses
没错 竹子与小麦 水稻及其它草一样
is a member of the Poaceae family.
都是禾本科的一员
Unlike trees,
不同于树木
which grow taller through the slow process of cell division,
竹子长高不是靠缓慢的细胞分裂过程
bamboo like all grasses-
而是像所有草一样
just inflate the cells it created before the shoot came out of the ground.
在竹笋破土而出前 内部细胞只是不断膨胀
Each new bamboo shoot
每棵新竹笋
is actually part of a larger system of roots and canes
都是一个更大的根茎系统的组成部分
that works like a plumbing system,
该系统就像个管道系统
pumping water into the new shoot’s cells.
将水分泵入新笋的细胞里
The cells release a special chemical
细胞释放出一种特殊的化学物质
that make their cell walls more flexible and inflatable
使细胞壁更有弹性更膨胀
and the orientation of the strands that make up these walls
同时构成细胞壁的纤维的方向
guide this fast growth straight up.
引导着竹子笔直向上快速生长
While all grasses grow via the same cell elongation process,
虽然所有草都是经由细胞伸长而长高
an unkempt lawn won’t end up towering over your house like a bamboo grove would.
但荒草丛可不会如竹子一般高过房顶
That’s because, unlike most grasses whose cell walls thin out and weaken as they stretch,
原因是大多数草的细胞壁随着伸长变薄变弱
bamboo is able to deposit more layers to its cell walls,
而竹子不同 它能沉积更多层细胞壁
keeping the shoot sturdy enough
使竹笋保持强韧
to withstand strong winds even as it grows to immense heights.
长得再高也足以抵御强风
It’s developed this ability in order to keep pace with the trees in the forests bamboo calls home,
这项能力使得竹子与原生地森林中的树木齐头并进
allowing it to get the necessary sunlight to supercharge
从而获得必要的阳光
the growth of even taller shoots next year.
在下一年加速长出更高的竹笋来
This firmly plants bamboo of the House Poaceae,
坚固无比的竹子傲立于禾本科殿堂
as the rightful Queen of the Forests,
是名正言顺的森林女王
the Unbent, the Breaker of Records,
正直不屈者 纪录打破者
and Mother- well, at least Nourisher- of Pandas.
以及熊猫的养母——至少也算供养者
And if, like bamboo, you’re all about moving fast,
如果你也像竹子一样追求快速行动

推荐下载“火之翼”系列
in which a mysterious group of young dragonets
书里讲述了一支神秘的小龙团
are tasked with trying to stop a war that’s raging among various dragon tribes,
肩负阻止龙族部落之间战争的任务
each with their own special traits.
每个部落都别具特色
It’s kind of like if giant violent sentient Galapagos finches
故事有点像庞大暴力又有情的加拉帕戈斯雀
had been sorted into Hogwarts houses
被分到霍格沃茨不同学院后
and then released on Middle Earth.
又被释放到中土世界
