plants seem to know which way is up and which way is down; besides, they seem to know right from left. if a cutting from a tree is kept alive, new shoots will grow from the end that grew in the highest part of the tree.
there is no noticeable difference between the top and the bottom of the living stick, even under a microscope. even so, the stick will not send out shoots from the end it regards as bottom even if this end happens to be on top!
scientists studying this subject further split their cuttings in the direction of length.
to their surprise, they made another new discovery. a good many more buds grew on the righthand side of the split surface than on the left. they split the sticks again and found that the buds again grew on the right side.
the results of the entire study showed a 60% choice for the right side, proving that growing plants are mostly "righthanded.”
植物似乎知道哪條路是向上的,而且它的方式是下降;此外,他們似乎知道從左。如果從一棵樹上砍下一棵樹,新的枝條將從生長在樹的高部分的末端生長。
即使在顯微鏡下,活桿的頂部和底部也沒有明顯的區(qū)別。即使如此,棍子也不會發(fā)出芽從年底它作為底部,即使這樣的結(jié)局發(fā)生在頂部!
研究這個課題的科學(xué)家在長度方向上進(jìn)一步分裂他們的巖屑。
讓他們驚訝的是,他們發(fā)現(xiàn)了另一個新發(fā)現(xiàn)。一個好的許多芽長在剖分面右邊比左邊。他們又把樹枝劈了,發(fā)現(xiàn)右邊的芽又長了。
這項研究的結(jié)果表明,右側(cè)為60%選擇,證明了植物生長的大部分是“右手”。
