When anthers were cultured on ms medium with 2 . 0 mg / l 6 - ba and 0 . 5 mg / l naa , the inducing rate of darslect and toyonaka was as high as 98 % and 85 % respectively 草莓的基因型不同，诱导率不同，达赛和丰香的诱导率分别为98和85 ，达赛的诱导率明显高于丰香。
After 4 times selected culture by ppt , 347 resistant calli were obtained . the ppt resistant calli were transferred to ms medium with 2 . 0 mg / l 6 - ba , 0 . 1 mg / l naa for regeneration 0mg l +蔗糖30g l的选择培养基中进行选择培养，每10天继代1次，连续选择4次，共得到347块抗性愈伤组织。
86 . 7 % buds surrived on 1 / 2 ms containing 250 mg / 1 km after 28d . two of six buds were dead 40d after that were put on 1 / 2ms medium containing 0 . 1 mg / 1 naa , and the tall of other four buds was less 2 cm 筛选后的芽在1 / 2ms + naao . 1培养基上生长40天后无根形成，并且6株芽中2株黄化死亡，其余4株高度不到2cm 。
Addition of img / l tdz and img / l naa resulted in the highest bud regeneration rate ( 67 . 9 % ) and number ( 35 ) of buds per explant . regeneration rate could be improved apparently in the medium with agno3 1mg ltdz和1mg lnaa配合对子叶再生具有极强的诱导作用，再生率最高，达到67 . 9 ，平均每外植体不定芽数达35个。
0 mg / 1 6ba . shoot buds were formed on subcultured pieces of callus with ms medium containing 0 . 3 mg / 1 naphtaleneacetic acid ( naa ) and 2mg / 16ba . the regenerated shoots rooted readily on ms medium plus 0 . 5 mg / 1 naa 研究发现精氨酸( arg ) 、甲硫氨酸( met ) 、丝氨酸苏氨酸( ser thr )并不是黄精凝集素生物学活性的必需基团。
It is easy to induce callus derived from hypocotyls and cotyledons , but callus derived from root tip was rather difficult to be done . the most suitable medium for callus induction was the ms medium containing ba 0 . 5 mg / l and l . omg / l naa 愈伤组织的诱导与再分化的研究显示： “种都一号”儿菜下胚轴与子叶愈伤组织诱导较容易，但根尖很难愈伤化。
The enriched stable isotope tracer technique combined with neutron activation analysis and differential centrifugation was utilized to investigate the subcellular distribution of rare earth elements sm and yb in rat liver Sm和, sup 168 yb作为示踪剂，结合差速离心分离和中子活化分析技术naa初步研究了稀土元素sm和yb在大鼠肝脏亚细胞组分中的分布。
High frequency of bud induction was found on ms medium supplemented with 6 - ba the optimum medium for adventitious bud induction was ms + l . 0mg / 1 naa + 0 . 5mg / l 6 - ba , and ms + 1 . 5mg / l naa + 0 . 5mg / l iaa for bud rooting 门）诱导毛状根体细胞胚再生植株。通过正交实验筛选出了毛状根体细胞胚诱导的最佳培养基为： ms 05mg lnaa 0 sing kt 30gil蔗糖。
Naa can not only defend the invasion of various microorganism , but maintain the stability of internal envioment , lead to self tolerance , regulate immunity and prevent tumor progression 从不同角度对naa的研究显示： naa的产生可能与自身反应性b细胞克隆阳性选择过程有关； naa对外可以抵御外来微生物的入侵；对内可以维持机体内环境的稳定，引起自身耐受，调节免疫和抗肿瘤。
Among the three factors tested in our experiments , kt had the significant effect on the somatic embryo induction and its development , followed by naa sucrose had smallest effect on somatic embryo induction , but had the obvious effect T 、 a浓度和蔗糖对体胚的发育均有较明显的作用。对体胚的发育最好在cling l的kt浓度下或不含激素的培养基中，蔗糖浓度最好在30g l 。
