These uncontaminated explants showed that morphogenetic potential were 70%-75% and each responding explant had 1.2-1.4 shoots formation on MS medium supplemented with 2 mg/L NAA and 16 mg/L BA. Moreover, adding antibiotics (100 mg/L Rifampicin and 100 mg/L Gentamycin) to solidify MS contained 3% galactose were tested, results showed the lowest contamination rates were 20% and 1.0-1.2 shoots were regenerated per responding explant. The antibiotic treatments with 100 mg/L Rifampicin and 100 mg/L Gentamycin could reduce internal contaminants, while the addition of antibiotics into medium in vitro culture led to phototoxic phenomena of axillary explants, morphogenetic potential lost and the growth of regenerant was also inhibited.

以100 mg/L Rifampicin+100 mg/L Gentamycin或100 mg/L Rifampicin+100 mg/L Gentamycin+150 mg/L Streptomycin组合浓度处理者，具有显著降低污染率的效果分别为60%及50%；克服内生菌污染而建立初代无菌培养之腋芽培植体，则以100 mg/L Rifampicin或以100 mg/L Rifampicin+100 mg/L Gentamycin处理者，芽体再生率最高70%-75%，惟平均每一腋芽培植体芽体增殖数仅1.2-1.4个；另在醣种类及浓度与抗生素试验，显示100 mg/L Rifampicin+100 mg/L Gentamycin之抗生素浓度组合添加至含3g/L半乳糖的培养基，显著降低污染率至20%；但未污染之培植体，形态发生潜能低至40%以内，可反应生长之培植体芽体形成数也仅达1-1.2个之间，再生芽体之生长也显现抑制现象。
