| 1 | Porogamy The usual method of fertilization in angiosperms in which the pollen tube enters the ovule by the micropyle. Compare chalazogamy. | |
| 2 | An ovary locelle produced about 160-240 ovules . | |
| 3 | The germination rate of "Venus seedless" embryos was efficiently promoted through beak cutting of the ovule. | |
| 4 | Pollen is usually blown to other trees and fertilizes their ovules. | |
| 5 | This paper reviews the progress made in the investigation of ovule development. |
