| 1. | Embryo rescue of interspecific hybrids between wild diploid dendranthema species and dendranthema morifolium 菊花二倍体野生种与栽培种间杂种的幼胚拯救 |
| 2. | Mesophyll protoplast fusion of solanum tuberosum and solanum chacoense and their somatic hybrid analysis 马铃薯栽培种与野生种叶肉细胞融合及体细胞杂种鉴定 |
| 3. | The standardized production was realized by fine management of secondary spawn and culture spawn for edible mushrooms 对食用菌原种和栽培种生产进行细化管理,实现其规范操作、规范生产。 |
| 4. | Today , about 15 species and more than 25 clones of gesneriaceae plants have been conserved in vitro and propagated . a procedure for the in vitro regeneration shoots via organogenesia of gesneriads is described 到目前为止,已成功培养了15种(共25个栽培种)苦苣苔科植物,栽培成活约1500盆(株) 。 |
| 5. | Results showed that the pollen grain of p . mira , which is used as material by sem for the first time , was nearly elliptic in shape and the extine pattern was simply striped with no pores 结果表明,光核桃花粉粒的形态呈椭圆球形,其外壁纹饰呈简单的直纹平行型,无穿孔,是最原始的桃亚属植物野生种,未发现与栽培种有直接的关系。 |
| 6. | This article introduces the production of edible fungi secondary spawn and culture spawn from preparation of substrate , medium sterilization , sterile working technique , cultural condition , cultural inspection and storage condition in detail 摘要从配料、灭菌、无菌操作技术、培养条件、培养检查、贮藏条件几个方面对食用菌原种和栽培种生产工艺技术要求进行了详细陈述。 |
| 7. | At present , there are six wild mulberry varieties , five varieties and more than 400 germplasm resources with the varied ecological types and utilization values , which indicates that the mulberry germlplasm resources in guizhou is the important wild mulberry germplasm resource bank in china 表明,贵州省目前有野生桑种6个、栽培种5个,并具有丰富的生态类型和种质资源( 400多个) ,分布广,类型多样,是我国重要的野生桑种质资源库,具有非常重要的利用价值。 |
| 8. | The karyotypes often of them were analysed . the rapd fingerprints and systematics of thirty wild species including the fourteen wild species mentioned and two cultivars in the family were studied . these were intended to provide theoretical reference at the cytological and molecular lever for species identification , systematics study and breeding work of these plants 本文对海南境内的14个野生种菊科植物进行了染色体计数,并对其中的10个种进行了核型分析,同时对包括上述14个种在内的30个野生种菊科植物和2个栽培种菊科植物进行了rapd指纹图谱与系统学研究,旨在为这些植物的物种鉴定、系统学研究和育种工作提供细胞学水平、分子水平的理论依据。 |
