图2. 60Co-γ射线辐照处理后牛至的形态变异
(A)-(D) 苗期突变: 矮化(A)、基部分枝(B)、节间距缩短(C)和花期提前(D); (E)-(H) 花色变异: 对照株(CK)花瓣粉白色(E)、变异株20-2花瓣粉色(F)、10-11花瓣白紫相间(G)和10-4花瓣紫色(H); (I)-(L) 株型变异: CK匍匐(I)、突变株20-13直立(J)、30-5直立(K)和10-19直立(L); (M) 叶片形态突变, 从左至右依次为CK、10-4、20-2、20-19、30-8和40-6。Bars=2 mm

Figure 2. Phenotypic variation of oregano individual plants after 60Co-γ radiation
(A)-(D) Mutation at seedling stage: dwarfing (A), basal branching (B), shortening of internode spacing (C), and early flowering (D); (E)-(H) Variation of flower color: the petals were pink-white in control (CK) (E), pink in mutant 20-2 (F), white and violet in mutant 10-11 (G), and violet in mutant 10-4 (H); (I)-(L) Variation of plant shape: the plant shape changed from creepers of CK (I), to up straight of 20-13 (J), 30-5 (K), and 10-19 (L); (M) Variation of leaf morphology, from left to right were CK, 10-4, 20-2, 20-19, 30-8, and 40-6.
