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。

First, it was to obtain two binary images from segmenting image by two thresholds. Second, erosion, opening and closing were done to the two images according to some knowledge of the shape and location of the objects in the image that we have already known. Last, the edge information from the image segmented by a high threshold was put into the image segmented by a low threshold. It is the way to segment and discern circular objects accurately from the complex image and can greatly improve the accuracy rate of discerning.
