植物生长的极性現象,有些是我們所熟悉的,不論是参天的巨木,还是矮小的野草,都是根莖各走极端:一个向下,一个向上。生理学上就是說根具有正向地性,而莖具有負向地性。此外,植物还有向光性、向化性等。但你可知道植物有顺着或逆着磁場生长的特性嗎?这个有趣的現象就是向磁性,它是苏联学者克雷洛夫发現的。这是一項很有意义 Some of the polar phenomena of plant growth are familiar to us. Whether it is a towering giant tree or a dwarf weed, each of its roots is extreme: one downward and one upward. Physiologically speaking, the roots have a positive geology, and the stems have a negative geology. In addition, plants also have light and tropism.
