Regale Wils, Marrero×Mero Star, Pollyanna ×mixing-pollen, MS + 1 mg/L 6-BA + 0.1 mg/L NAA was a good medium; while for Snow Queen ×L.pumilum, MS + 0.5 mg/L 6-BA + 0.1 mg/L NAA can good for germination.

从试验中所研究的组合来看：White Fox ×L.regale Wils、Marrero ×Mero Star、Pollyanna ×混合花粉的胚在Ms 并附加1 mg/L 6-BA 和0.1 mg/L NAA 的培

No callus could be induced from leaf or petiole explants of varieties F30 and Ⅱ cultured on MS medium if supplemented alone with 6-bezyladenine （6-BA） or thidiazuron, or kinetin. However, the calli were induced on MS medium containing 2.0 mg L-1 6-BA and 0.5 mg L-1 NAA （α-naphthaleneacetic acid）, and the calli derived from petioles of variety Ⅱ could produce redifferentiated shoots, but of variety F30 could not. The later could only produce shoots directly from the base of the petioles.

将品种F30和Ⅱ的叶片和带叶叶柄接种到含不同浓度单一细胞分裂素（6-BA、TDZ、KT）的MS培养基上培养，均未能诱导出愈伤组织，而在含2.0mgL-1 6-BA＋0.5mgL-1 NAA的培养基上可以诱导出愈伤组织，且由品种Ⅱ叶柄诱导产生的愈伤组织可再分化出芽，品种F30诱导的愈伤组织却不能分化，但在其叶柄基部可直接出芽。

Factors that influence percentage of transformation including time of preculture, dipping and coculture, type and content of antibiotic, day of delayed selection culture, intension of selection were studied. The effective transformation system of "Starkrimson" was developed as follow: Leaves precultured in darkness for three days were dipped into agrobacterium suspension for three minutes, then were cocultured in darkness on MS medium with TDZ0.5mg/L and NAA 0.3mg/L for three days, and then cultured in darkness on MS medium with TDZ0.5mg/L NAA0.3mg/L and Cef 250mg/L.

通过对叶片预培养时间、侵染时间、共培养时间、抑菌素种类和浓度、延时筛选时间、不同选择压等遗传转化影响因素的研究，建立的'新红星'苹果遗传转化体系为：叶片黑暗预培养3天，经农杆菌侵染3分钟，在含TDZ0.5mg/L，NAA0.3mg/L的MS培养基上黑暗共培养3天，然后加250mg/L Cef黑暗维持培养3天，再进行Km12.5mg/L的选择压黑暗培养至抗性愈伤出现；转为光照条件1-2次的继代筛选，获得抗性芽后，进行扩繁。

Even carbon number alkenes, phthalic esters and nitrogen heteroatom-containing components were detected in the elution fractions, while such components were not detected without silica gel column separation, indicating that preseparation is very important for increasing the sensitivity of GC/MS analysis.

各洗脱馏分用GC/MS分析，其可测成分与直接检测相比，多检测出偶碳烯烃、邻苯二甲酸酯类和含氮化合物等，表明合适的预分离对提高GC/MS分析的灵敏度非常重要。

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。
