摘　　要：阴山荠属（Ｙｉｎｓｈａｎｉａ）和泡果荠属（Ｈｉｌｌｉｅｌｌａ）受试种类的染色体数目是：柔毛阴山荠（Ｙ．ｈｅｎｒｙｉ（ｏｌｉｖ．）Ｙ．Ｈ．Ｚｈａｎｇ）２ｎ＝１２，叉毛阴山荠（Ｙ．ｆｕｒｃａｔｏｐｉｌｏｓａ（Ｋｕａｎ）Ｙ．Ｈ．ｚｈａｎｇ）２ｎ＝１２，双牌泡果养（Ｈ．ｓｈｕａｎｇｐａｉｅｎｓｉｓＺ．Ｙ．Ｌｉ）２ｎ＝４４，黟县泡果齐（Ｈ．ｙｉｘｉａｎｅｎｓｉｓＹ．Ｈ．Ｚｈａｎｇ）２ｎ＝４２，奇异泡果荠（Ｈ．ｐａｒａｄｏｘａ（Ｈａｎｃｅ）Ｙ．Ｈ．ＺｈａｎｇｅｔＨ．Ｗ．Ｌｉ）２ｎ＝４２。两属皆具ｘ＝６，７的基数，但泡果荠属具较高的倍性。过氧化物酶同工酶酶谱显示，两属受试植物各具属相似性，在各属内，不同种的酶谱存在差异性。染色体数目和过氧化物酶同工酶酶谱的差异以及形态特征和地理分布的不同，表明这两属分立为独立的属是自然的。he chromosome numbers and peroxidase zymograms of 5 species of 2 genera , Yinshania andHilliella,Cruciferae are reported. Their chromosome numbers are as follows : Y. hanryi(Oliv.)Y.H.Zhang, 2n = 12;Y. furcatopilosa (Kuan)Y.H.Zhang, 2n = 12;H. shuangpaiensis Z.Y. Li, 2n = 44;H.yixianensis Y.H. Zhang, 2n = 42;H. paradoxa(Hance)Y.H. Zhang et H.W. Li , 2n = 42. Now it is known that both Yinshania and Hiafora have same base chromosome numbers x=6,7,but Hilliella is polyploidy.The peroxidase zymograms shows that the re are generic si milari ties and specific variance among the species. The di ffrence of chromosome numbers and peroxidase zymograms with that of morphological charac ters and geographical distribution of t wo ge nera indicate that they are natural as an independent genus respectively.
