The results indicated that chromosome counting was the most reliable and precise method, however, it was cumbersome and required skilled cytological techniques; The chromocenter size, heterochromatin number, chroloplast number of guard cell and certain plant morphological characteristics are simple and practical methods for ploidydetermination but with some shortages.

结果表明：对体细胞染色体的直接计数法是最可靠的方法，但费时、难度大；叶片气孔大小与倍性无显著相关性；保卫细胞叶绿体数目、体细胞染色中心大小以及异染色质个数与黄瓜倍性密切相关，是简单、快速而有效的倍性鉴定方法；植株的形态学观察也能间接确定植株倍性，但鉴定时期偏晚，精确性较差。
