摘要：中学生几乎人人皆知“南橘北枳”成语故事，事实上“南橘北枳”现象是不存在的初中《生物学》中引用“南橘北枳”来说明环境因素引起的变异违背了科学性原则。本文介绍了橘和枳生物特性，探讨“南橘北枳”产生原因，以及分析了几种不遗传变异的现象。

Analysis on "Orange changes in different environs" based on mutation of environ
Abstract
It is well known that Orange changes feature in different environs, but this is not the case. In order to describe the mutation caused by environ changing, the story that "Orange changes in different environs" is introduced by textbook in middle school, which violates the basic scientific law. In this paper, features of Citrus reticulata Blanco and Poncirus trifoliata Raf. are discussed, the cause and some non-heritable mutation phenomena also are analyzed.

就是由于气候的原因橘子种在南方才会正常发育，而到了北方就长成了又苦又涩的比橘子小的果实。这就是南橘北枳。

这个不好翻译的，和功夫是一样的，你可以直接Nanjubeizhi，然后解释一下什么意思就好了
