Growing Plants Know Right from Left
Plants seem to know which way is up and which way is down；furthermore, they seem to know right from left.If a cutting from a Lombardy poplaris kept alive, new shoots will grow from the end that grew uppermost in the tree.
There is no visible 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 views as bottom even if this end happens to be on top！
Scientists, studying this subject further split their cuttings lengthwise.To their surprise, they made another interesting discovery.A good many more buds grew on the right-hand 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 60-40 preference for the right side, proving that growing plants are basically “right-handed”。
生長中的植物能分辨左右
植物似乎知道哪邊朝上，哪邊朝下；而且，它們似乎還能分辨左右。從倫巴第白楊上砍下的一根枝條如果還活著，原來長在樹的高處的那一端便會抽出新芽。
這根活枝條的頂部與底部并無明顯差別，即便在顯微鏡下看也是如此。盡管這樣，枝條卻不從顯微鏡觀察是底部的那一端抽芽，即使這一端碰巧朝上。
研究這一課題的科學家們進一步把他們砍下的枝條縱向切開，使他們驚訝的是，他們又獲得另一項有趣的發(fā)現(xiàn)。切口表面右側(cè)長出的嫩芽比左側(cè)多得多，他們把枝條再切開，發(fā)現(xiàn)嫩芽還是長在右側(cè)。
全部研究的結(jié)果表明，植物愛偏向右邊，向左偏的只占40％，而向左偏的卻占60％。這證明了生長中的植物基本上是“右撇子”。
