【摘要】 试验以限制生长保存的龙眼胚性愈伤组织为材料,测定了3个龙眼品种红核子、松风本、苗翘在4种不同培养基中限制生长保存过程中淀粉含量变化。研究结果表明:龙眼不同基因型以及不同培养基限制生长保存过程中,淀粉含量变化都有所不同。红核子在A、B、C培养基中出现2次积累高峰,在D培养基出现3次积累高峰;苗翘在A、B培养基中出现2次积累高峰,C、D培养基中出现3次积累高峰;松风本在A、D培养基中只有1次积累高峰,而在B、C培养基中有2次积累高峰。更多还原

【Abstract】 The changes of starch contents of longan embryogenic calli(EC) from the three longan cultivars(Honghezi,Songfengben and Miaoqiao) were tested during in vitro conservation in this experiment.The results showed that the accumulation peak time of the starch contents of 3 cultivars cultured on 4 media were different.The accumulation peaks of Honghezi EC cultured on Medium A,B,C presented two peaks,while cultured on Medium D presented three peaks;Miaoqiao EC cultured on Medium A and B presented two peaks,while cultured on Medium C and D presented three peaks;Songfenben cultured on Medium A and D presented one peak,while cultured on Medium B and C presented two peaks.更多还原
