| 1. | The primary chalazal haustorium ramifies around the vascular tissues of the ovule .
初生合点吸器沿着胚珠的维管组织分支。 |
| 2. | The mean number of ovules per follicle was 10 . 59 , n = 320
每心皮的胚珠数目为10 . 59 （根据320个心皮中胚珠的平均数） 。 |
| 3. | Morphological development of ovule - like organ on the leaf and variation characteristics of ginkgo biloba var . epiphylla mak . ohatsuki
叶籽银杏拟胚珠的形态发育及变异特性 |
| 4. | 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。 |
| 5. | Testa the hard dry protective covering of a seed , formed from the integuments of the ovule . after fertilization the layers of the integuments fuse and become thickened and pigmented
外种皮：覆盖在种子外部的坚硬干燥的保护层，由胚珠的珠被发育形成。受精作用后珠被各层发生融合并加厚着色。 |
| 6. | When ovule orientation is orthotropous the chalaza corresponds to the point where the funicle is attached but in anatropous and campylotropous ovules the chalaza is some distance from the funicle
当胚珠的方向是直生胚珠时，合点和珠柄连成一条直线，当胚珠是倒生胚珠或弯生胚珠时，合点和珠柄之间有一定的距离。 |
| 7. | Expression analysis the expression analysis of gharf in different tissues of cotton was carried out by rna dot blotting with ghakf probe labeled with dig . the result showed that the expression of arf gene was mainly in anthers of sterile and fertile , pollen of fertile , corolla rather than in leaves , radicel and ovule
棉花ari ； ’基因的表达分析用地高辛将棉花arf基因标记为探针，与棉花洞a的不育株花药、司有株花药、可育花粉粒、叶片、花冠、胚根和胚珠的总rna进行斑点杂交。 |
| 8. | For example ， the spiral arrangement of scale - bract complexes on ovule - bearing pine cones ， where the female reproductive organs of conifers are located ， is important to the production of airflow patterns that spiral over the cone ' s surfaces ， thereby passing airborne pollen from one scale to the next
例如，带有胚珠的松球的鳞苞综合体的螺旋状安排，亦即松柏目植物雌性殖器官的所在位置，对于气流模式的形成与产生殊为重要，而这些气流模式在松球的表现盘旋上升，从而把在空气中飞行的花粉从一个鳞苞传播至下一个鳞苞。 |
