Fig. 4. Proportion of total ovules divided into four intervals (starting at base line) corresponding to proportion of total ovules fertilized with proembryo at 24 hr after fertilization (HAP), proportion of total ovules fertilized but aborted embryo by 24 HAP, proportion of total ovules with normal egg sac components but not fertilized, and proportion of total ovules with defective components in the egg sac and not fertilized as a function of weeks after seeding. Values represent the mean ± SE of the mean of three replications for normal proembryos and aborted embryos, and one to three replications for defective egg sac.
