| 1. | Prolonged starvation and aging might lead to rejuvenation of embryogenic potential . 长期的饥饿和衰老可以导致胚胎发生能力的复壮。 |
| 2. | Establishment of embryogenic callus suspension culture system in liriodendron hybrids 杂交鹅掌楸胚性细胞悬浮系的建立 |
| 3. | Mutagenic effects of ion beams on embryogenic cell - aggregates of sweetpotato 离子束对甘薯胚性悬浮细胞团的辐射诱变效应 |
| 4. | Induction and genetic identification of embryogenic calli from hybrids of shatian pummelo 沙田柚杂种胚性愈伤组织的诱导及遗传鉴定 |
| 5. | The primary results of our experiment as list below : 1 . we established the agrobacterium - mediated transformation system used suspension embryogenic callus for infection 主要的实验结果如下: 1 、建立了保定苜蓿的农杆菌介导悬浮胚性愈伤遗传转化体系。 |
| 6. | Recent developments in molecular biotechnology are making this possible . in the work described here , three transgenic sublines of embryogenic norway spruce calli : a78 - 3 , a78 - 4 and a78 - 5 were studied 随着分子生物学技术的发展,通过转基因技术有目的地培育出木质素含量低的挪威云杉新品种就成为可能。 |
| 7. | Genotype mainly influences the frequency of embryogenic calli formation , 81 . 35 % immature embryo of yangmai 87158 can form embryogenic calli , while only 16 . 81 % immature embryo of annong 92484 can form embryogenic calli 基因型的影响主要影响到胚性愈伤组织的发生频率,以幼胚为外植体杨麦87158可以达到sl |
| 8. | Owing to the cofinement of the host of agrobactrium tumefliens and the difficulties of the maize inbred lines for obtaining embryogenic calli , the genetic system of maize was n ' t ideal enough 由于农杆菌介导玉米遗传转化受到农杆菌宿主的限制和玉米自交系获得再生植株难的影响,使玉米自交系遗传转化体系仍不完善。 |
| 9. | 4 . in the cultivation , wheat genotype , concentration of hormone in the medium and the kind of explant are the three key factors that influence frequency of induction embryogenic calli and plant regeneration 小麦离体培养中,基因型、培养基激素浓度与外植体类型是影响小麦胚性愈伤组织诱导和再生频率的3个主要因素。 |
| 10. | In all treatments of aseptic seedlings under 4 for different days , the treatment under 4 for 4 days produced the most amount ( 80 % ) of resistant embryogenic calli induced from hypocotyls 其中幼苗经4ac处理4天,从其下胚轴所获得的抗性愈伤最多,其抗性愈伤组织的诱导频率为80 % ,高于其它各处理的抗性愈伤组织的诱导频率。 |
