| It is unclear which or how many wild species or cultigens were the progenitors of the extant avocado races. |
|
| These sites had a domesticated plant system incorporating native and introduced cultigens, while the Mill Creek sites also exhibited a dispersed field location pattern. |
|
| Droughts, floods, or early frost may have caused some or all of the introduced cultigens to fail but may have resulted in bumper yields of the more weedy native species. |
|
| With one exception, components of galactogenic foods are plants, and most are cultigens. |
|
| However, the cultivation of padi and other cultigens such as maize, tubers, vegetables, and fruit trees in swiddens is central to their diet. |
|
| Domesticated plants deliberately altered or selected for special desirable characteristics are cultigens. |
|
| West Africa, however, presents distinctive characteristics, especially in terms of its cultigens, far removed from the modes and timing of the North African examples. |

| The Pharmacologic, Ecologic and Social Implication of Using Non cultigens. |
|
| In later stages, human alteration of the landscape is clearly detectable due to the virtual explosion of cultigens, especially during the last 3 ka. |
