| 1. | Review on the megastrobilus theories of conifers
松杉类裸子植物的大孢子叶球理论评述 |
| 2. | The female gametophyte is reduced , but larger than in angiosperms ; it is not autotrophic
裸子植物的雌配子体简化，但较被子植物体的体积大，不能自养。 |
| 3. | Bract scale the structure found in large numbers in the female cone of gymnosperms , each bearing an ovuliferous scale in its axil
苞鳞：在裸子植物的雌球果中大量存在的结构，每个苞鳞都包含一个珠鳞。 |
| 4. | Enclosure of the nucellus by the integuments is incomplete , the embryo sac or , in gymnosperms , to the archegonium
珠被并不是将珠心完全封闭，而是留有珠孔以便受精时花粉管进入胚囊，或裸子植物的藏卵器。 |
| 5. | The carpel is homologous with the megasporophylls of certain spore - bearing vascular plants ( pteridophytes ) and the ovuliferous scales of gymnosperms
心皮和能产生孢子的维管植物（羊齿类）还有具胚珠的裸子植物的大孢子叶是同源的。 |
| 6. | Albuminous cell 1 . a vertically elongated parenchyma cell , found in groups in the rays of the secondary phloem in gymnosperms , where they are associated with sieve cells
蛋白质细胞： 1 .在裸子植物的次生韧皮部薄壁组织和韧皮射线中发现的1种垂直伸长的细胞，通常与筛胞相结合。 |
| 7. | He also observed that gymnosperm ovules were not enclosed in an ovary wall , leading to the establishment of one of the basic differences between angiosperms and gymnosperms
他还观察到裸子植物的胚珠并不是被子房壁包围，这个发现直接导致了被子植物和裸子植物之间最根本的几点区别的建立。 |
| 8. | These genera and ephedra also hve advanced tracheids with a structure reminiscent of angiosperm vessels , whereas in other gymnosperms the xylem is composed solely of more primitive tracheids
这些属以及麻黄属植物和被子植物一样有进化的管胞，而其他的裸子植物的木质部只由很多导管组成。 |
| 9. | 5s rdna cloning and sequencing were carried out to analyze the 5s rdna variation pattern . genomic in situ hybridization ( gish ) was performed for better understanding of genomic relationship among closely relative pines
利用克隆测序方法对松属植物5srdna的研究无疑是有开创性的工作，可以探讨裸子植物的5srdna的进化机制和种间关系。 |
| 10. | The analyses of these three types of data in the hybrid and its parents could provide new information on genomic composition and evolutionary mechanisms of the hybrid . the main results are the followings : 1 . rdna fish chromosomal localization of 18s and 5s rdna was carried out for two soft pines ( subgenus strobus ) and five hard pines ( subgenus pinus ) using fish
Rdna荧光原位杂交( fish )通过对华山松和白皮松两种单维管束亚属植物及油松、云南松、高山松、马尾松和南亚松等五种双维管束亚属植物的18srdna与5srdna的荧光原位杂交，结果表明： ( 1 )裸子植物的18srdna位点数目明显多于二倍体被子植物。 |
