It was thought that proper high level of ABA and IAA content and low content of GA3 were benefit to induction of embryonic calli from immature embryos. 因此认为，未成熟胚高水平的ABA、IAA含量和低水平的GA3含量，有利于胚性愈伤组织的诱导。
The embryonic calli that had been cultured for half a year were transferred to the culture medium lacking phosphate and were screened. 将继代培养半年左右的胚性愈伤组织转移到去掉磷酸盐的培养基上进行筛选。
A peak value of ABA and IAA content and a low value of GA3 content in explant were detected at the beginning of embryonic calli generation. 在胚性愈伤组织开始发生之际，外植体的ABA和IAA含量出现峰值，GA3含量出现低谷。
Embryonic calli could be obtained from explants such as terminal buds and axillary buds of hybrid giant napier inoculated in induced media during tissue culture. 以皇竹草腋芽或顶芽作外植体，接种在脱分化培养基上培养，可获得胚性愈伤组织。
Abstract： Embryonic calli could be obtained from explants such as terminal buds and axillary buds of hybrid giant napier inoculated in induced media during tissue culture. 摘要：以皇竹草腋芽或顶芽作外植体，接种在脱分化培养基上培养，可获得胚性愈伤组织。
It was found, however, that ABA content of embryonic calli was lower than non-embryonic calli, and induction rate of embryonic calli was correlated negatively with IAA content of embryonic calli. 但是胚性愈伤组织的ABA含量却低于非胚性愈伤组织，且胚性愈伤组织诱导率与胚性愈伤组织IAA含量负相关。
Immature embryos of 9 maize inbred lines with different induction rate of embryonic callus were used as explants and calli were induced and cultured on improved N6 medium. 摘要以胚性愈伤组织诱导率高低不同的9个玉米自交系未成熟胚为外植体，用改良N6培养基诱导培养愈伤组织。
The results showed that the best media NN(NMB+NB) were in favor of the induction and regeneration of embryonic callus. 试验结果表明:培养基组合NN(NMB+NB)有利于胚性愈伤组织的诱导和分化。
The best dry time for embryonic callus is 9 hrs, its embryogenesis frequency exceed 9.10% compared with CK, reaching 12.67%. 愈伤组织干燥时间选择9小时最好，胚状体发生率为最高，达12.;67%25，比对照高出9
The study aimed on the selection of embryonic callus of Kalanchoe blossbeldiana, the induction of embryoid, morphogenesis of embryoid and regeneration. 研究了长寿花胚性愈伤组织的筛选,胚状体的诱导发生、发育过程及植株再生。
Embryonic callus of Kentucky bluegrass were used as material for genetic transformation with the DREB1A gene, BADH-CMO double-gene and CMO gene by particle bombardment. The transgenic plants were obtained. 在此基础上,通过基因枪轰击法把与抗旱、耐盐有关的外源基因(DREB1A、BADH-CMO、CMO)对草地早熟禾胚性愈伤组织进行遗传转化,经过潮霉素筛选、PCR扩增与Southern杂交检测,获得了转基因植株。
However, the percentage of embryonic callus and average number of somatic embryos per explant had relation with botany type of peanut varieties on MS+picloram 5mg/L medium, and Spanish type were higher than the Virginia. 在 MS+5mg/ L Picloram培养基上 ,胚性愈伤组织发生率和产胚量与品种类型有关 ,珍珠豆型花生品种胚性愈伤组织发生率和产胚量高于普通型花生品种。
Transforming IPX gene to GSDUR and transgenic plants was obtainedOn the basis of the above mentioned genetic transformation system, chimeric gene PSAG12-IPT was transformed to the embryonic callus tissue of GSDUR through Agrobacterium-mediated method. IPT基因遗传转化谷秆两用稻，获得转基因植株
The scheme is still in its embryonic stage. 她脱颖而出成为著名艺术家。
Our studies confirm that embryo development stages have a great effect on embryonic callus induction, and we discuss the culture conditions of somatic embryogenesis of Pinus armandii. 文章确认了采集的幼胚发育状态对胚性愈伤组织的诱导有重要影响, 并对诱导的培养条件等进行了探讨。
An embryonic nation, not yet self-governing. 一个早期的国家，还没有自治

inoculated in the DCR medium can induce calli only, with the frequency of similar embryonic calli of 47.62%. 将幼胚接种在DCR培养基上只能诱导出愈伤组织;其中类似胚性愈伤组织率最高达到47.;62%25。
were: DCR+2,4-D10mg/L+BA4mg/ L +CH,Myoinositol 1000mg/L individually +Gln 500mg/L,with the highest frequency of similar embryonic calli of 21.58%. 华山松成熟胚诱导愈伤组织的培养基成分为:DCR+2;4-D10mg/L+BA 4mg/L+CH;肌醇各1000mg/L+Gln500mg/L;其中类似胚性愈伤组织诱导率达到21.;58%25。
