The stem segments and tips of red raspberry,"Fengmanhong" and yellowberry were used as explants to study their isolated culture and plant regeneration frequency in vitro culture.
以无刺红、丰满红、黄树莓3个树莓品种为试材,取其茎尖和茎段为外植体,进行了离体培养与植株再生频率的研究。
The results showed that the difference of the regeneration frequency among the difference varieties were significant,and that the regeneration frequency of cotyledon with petioles were better than hypocotyl,in which the variety \'85-1\' had the highest frequency,followed by \'Tianjin Qinmaye\',and \'Beijing Xinsanhao\' had the lowest.
3个基因型间,‘85-1’的再生频率最高,‘天津青麻叶’次之,‘北京新三号’最低;2种外植体中,带柄子叶的再生频率显著高于下胚轴;22个激素组合中,TDZ 0。
In order to solve the problem of explant contaminations and promote the regeneration rate of the potato transformation system,the sterling method of potato tubes has been greatly improved to lower the contamination rate to almost zero.
为提高马铃薯遗传转化体系的再生频率,改进了受体薯片的消毒方法,解决了外植体易污染问题,使污染率几乎降低为零;共浸染时加入适量的乙酰丁香酮可以提高再生频率;适当降低芽分化培养基的激素水平,在外植体分化正常的情况下,节省了在激素上的资金投入;不同品种马铃薯片转化后的植株再生情况不同,津引薯8号微型薯出苗量大,而S1微型薯首批苗更好。
