( 3 ) the optimal explant age for transformation was 6 or 7 day after aseptic germination of seeds. ( 4 ) development of non - transformated cell was inhibited completely by 100mg / l kan. ( 5 ) 500mg / l cb could avoid pollution of agrobacterium tumefaciens and had no distinct effects on the formation of callus and shoot regeneration. ( 6 ) the optimal co - cultural condition was 3 day on 28 in dark
以胡蘿卜品種「改良黑田」為受體材料,以胡蘿卜幼苗的下胚軸為外植體,建立了農桿菌介導法的胡蘿卜轉化體系,並對其中的種子消毒、激素水平、外植體的苗齡、選擇壓、共培養時間等關鍵步驟的條件進行了優化。 -
It was also noted that irradiation treatment with low dose ( 10gy ) of y rays exerted slight stimulating effects on callus induction and formation of embryogenic calli in particular. production of embryogenic calli was obviously promoted by addition of 0. 1 ~ 0. 2mg / l bap or 2. 5mg / l cuso4 5h2o, or enhancement of sucrose concentration to 60g / l in subculture medium
在繼代培養基中添加0 . 1 0 . 2mg lbap或2 . 5mg l硫酸銅,或將繼代培養基中蔗糖濃度提高到60g l能促進胚性愈傷組織發生,提高胚性愈傷組織頻率。 -
