| As the stamens in each flower and umbel ripen a few days earlier than do the pistils, cross-pollination occurs more often than self-pollination. |
| The total number of pistils, parthenocarpic and seed containing siliques, and the mean number of seeds per silique were recorded. |
| Males produce only staminate flowers with stamens and no vestigial pistils. |
| Based on the presence or absence of fertile stamens and fertile pistils, the heads can be further classified into heterogamous and homogamous capitula. |
| The fresh pistils are less white than those on the Warlock but the mature pistils are tan as well. |
| Leaf discs and the unpollinated pistils of unopened flower buds from both the control and HTS-treated plants were also collected for total RNA extraction. |
