（ 2 0mg l ）上培養30d后經過體細胞胚胎發生途徑產生大量的叢生苗；子葉培養在誘導子葉產生叢生苗培養基（ msoc ） ms ba （ 2 0 。 -
Cotyledon without petiole showed a significantly lower frequency of shoot regeneration ( 16. 7 % ) compared with that of entire cotyledon ( 33. 8 % ), but the average number of shoots per explant ( 4. 2 ) was more than that of entire cotyledon ( 2. 5 ). no shoot was obtained when the petiole alone was cultured. the frequency of shoot regeneration ( 8. 3 %, 12. 5 % ) and average number of shoots per explant ( 2. 3, 1. 7 ) from the upper section of lamina or one side of lamina was lower than those of entire cotyledon
另一方面，以「種都一號」兒菜的不同子葉部位作為外植體所進行的研究結果表明，不帶子葉柄的完整葉片其芽再生率（ 16 . 70 ）顯著低於帶子葉柄的完整子葉（ 33 . 8 ） ，但平均再生芽數，前者（ 4 . 2 ）卻高於後者（ 2 . 5 ） ；子葉柄不能進行芽的分化；不帶子葉柄的子葉尖端和子葉一側，其芽再生率（分別為12 . 5 、 8 . 30 ）及再生芽數（分別為2 . 3 、 1 . 7 ）也明顯低於帶子葉柄的完整子葉。
