Summary
This work reports some findings which will aid us in our understanding of the female phase ofPisum sativum embryology. We have observed that the central planes between one ovule and the next form an angle of 60°. We suggest that this ovule arrangement may make it easier for the pollen tube to reach the ovular micropyle in the fertilization process. On the other hand, ovary and ovule growth do not depend on the megasporogenesis stage but have individual characteristics for each plant, every one depending on its own phenotype.
