查询词典 NAA

The increment of 6-BA concentration can increase the protocorm propagation obviously. And the matching of high concentration of 6-BA and low concentration of NAA is more suitable for the protocorm propagation of C. grandiflorium. 6-BA at the concentration of 1.5 mg/L was most favorable for protocorm induction and differentiation.

结论］6-BA浓度的增加，可明显提高原球茎的增殖，高浓度6-BA与低浓度NAA的配比较适合大花蕙兰的原球茎增增殖；6-BA在1.5 mg/L时最有利于原球茎的诱导分化。

Results were as follows: in MS basic medium+KT2mg/L or 2ip, the two varieties growed well. Appending NAA0.2 mg/L could promote radication commonly. But in MS+BAP2 mg/L there was obvious difference from the two varieties. Chinese yam rhizome axillary bud was restrainted. But feng yam was prone to form fascicular bud. When supplemented with NAA0.2 mg.L-1, NAA and BAP could accelerate Chinese yam rhizome axillary bud growth and increase the number of buds.

结果表明：两品种在MS+KT2mg/L或2ip培养基上生长情况均较好，当附加NAA0.2时，一般可促进生根；但在培养基上，两品种差异明显，淮山药表现腋芽生长受抑制，而凤山药则易形成丛生芽，而当此培养基附加NAA0.2时，NAA与BAP可协同作用促进淮山药的腋芽生长，增加芽苗数，但对凤山药的生长则基本无影响。

The stem segment, leaf and fruit of Talinum paniculatum were used as explants to induce the calluses by means of incubating them on MS medium supplemented with different concentration of NAA and 6-BA.

以MS为基本培养基，附加不同浓度的NAA、6-BA，研究不同激素水平对茎段、叶片、果实愈伤组织诱导的影响。

Among different organ explants from ginger lily, only sheaths and leaves cultured in VW medium containing 5mg/l 2, 4-D、0.5mg/l BA、3% sucrose and 200ml/l coconut water for 3 months could be induced to form embryogenic callus. It could produce lots of germinated or ungerminated somatic embryos per culture directly from the surface of calli after culture in MS medium containing 4mg/l BA and 0.05mg/l NAA. The shoots could develop into intact plants with vigorous appearance after 2 months in culture.

叶鞘及叶培植体在含5 mg/l 2，4-D，0.5 mg/1 BA、3%蔗糖及200 ml/1椰子水的VW固体培养基中，经3个月，可诱导产生具体胚分化能力之愈合组织；并於含4 ms/l BA及0.05 ms/l NAA之MS培养基中，直接由此愈合组织的表面产生数个至数十个数目不等之体胚，2个月后可形成一完整植株。

Young fruit of Zizyphus mauritiana were smeared with plant growth substances, GA3, NAA, ABA or 6-BA, at the concentration of 20 mg/L or 50 mg/L, 40 days after falling of flowers.
