在植物教科书或作物栽培学中(包括全国统编教材),几乎都把种子的“胚轴”一词解释为:胚轴:可分成上胚轴与下胚轴两个部分。由子叶着生点至第一片真叶之间的部分叫做上胚轴;子叶着生点以下至胚根之间的部分叫做下胚轴。我认为上述解释不妥,并同意伊梅斯(Eames 1961年)的意见,即胚轴(embfyo axis)在过去是指“胚茎”和“胚根”,这些名词现在很少使用。多数胚未形成真正的茎;所谓“胚茎”是指下胚 In plant textbooks or crop cultivation (including nationally integrated textbooks), the word “hypocotyl” of seeds is almost always interpreted as: Hypocotyl: It can be divided into two parts: hypocotyl and hypocotyl. The part from the cotyledon to the first true leaf is called the hypocotyl; the cotyledon below the birth point to the radicle is called the hypocotyl. I think the above explanation is wrong and I agree with Eames (1961) that the embfyo axis used to mean “embryo stem” and “radicle” in the past, and these terms are now rarely used. Most embryos do not form a true stem; the so-called “embryo stem” refers to the embryo
