TEL AVIV — The Botanical Garden is a blooming paradise, about four hectares filled with a rich array of some 3,800 species drawn from Israel’s diverse landscape and from around the world.
这座植物园是个鲜花盛开的天堂,4公顷的土地上种满了来自以色列各地和全世界的3800种植物。

Danny Chamovitz, director of the Manna Center for Plant Biosciences at Tel Aviv University, visits the garden often to conduct research or just to take a stroll. It's the perfect setting to talk about his new book: “What a Plant Knows: A Field Guide to the Senses.”
Danny Chamovitz是特拉维夫大学植物生物学甘露中心主任,他经常来花园做研究,或者溜达着。这里的景色与他的新书相映成趣:“植物知道什么:野外感官指南。”

“I wrote the book because I had come to realize that a lot of what I take for granted -that plants have senses, that plants see, that plants smell, that plants know when we’re touching them - most people don’t know," he said. "And so I wrote the book to show how complex a plant’s life is and to show the science behind it.”
“我之所以写这本书,是因为我意识到很多自己以为理所当然的知识,比如植物有感官、能看东西、有嗅觉,人触摸时能感知到,而这些知识很多人是不知道的。所以我就写了这本书,向人们展示植物生活的复杂性,展示背后的科学知识。”

Earlier in his career as a post-doctoral fellow at Yale University, Chamovitz researched how plants use light, isolating the genes responsible for photosynthesis. Sitting beside a shade tree, he gently pulls on a low-hanging branch, thick with leaves.
Chamovitz早先在耶鲁大学做博士后研究人员,他研究了植物如何利用光线、隔离负责光合作用的基因。他坐在树荫下,轻轻拉过一个低低的茂密树杈。

“You can see that its stems are longer than the ones that are at the top, which are in the light," he said. "And it knows this because it can actually differentiate between higher amounts of light and smaller amounts of light and it uses this information either to make itself longer to get toward the light, or once it’s in the light, to make its leaves broader so that it can do its photosynthesis and make the energy.”
“你可以看到这段树杈的茎比树顶部有光照的要长,植物能分辨出强光和弱光,能利用这些信息让自己长长些,或者接近阳光,一旦有光照,植物就会让自己的叶子变大,这样就可以进行光合作用,从而制造能源。”
