自地球上出现植物以来，它们之间的生存竞争普遍存在，十分激烈，其至是你死我活的。很多植物的种族间，一直在进行着殊死的“化学战”。例如，荞麦的分泌物可显著地抑制冰草、看麦娘等杂草的生长；小麦与黑麦生长在一起，无论水肥条件怎样优越，小麦必然生长不良；而在水

美国一位昆虫学家罗伯特·哈克发现，当植物处于严重缺水状态时，维管束会因承受不住因缺水造成的拉力而绷断，并发出比人们说悄悄话低１万倍的嘁嘁喳喳声。害虫对发生水分危机的植物蜂涌而上，大吃大喝。因此，植物缺水，不仅其代谢出现问题，而且还会招致害虫的侵扰。为...

世界上的树木（包括高１３２米的王桉，１１５米的红杉“世界爷”）为何不能无限长高呢？根据达尔文的“自然选择”理论，现今的树木就是适应现今环境的佼佼者。试想，如果树木无限地长高，那就要招来风折雷劈等横祸；还会造成阳光、氧、水、养料供给不足，还要受温度等限...
