| If this information is not included for any variety, the ploidy is to be regarded as unknown, and thus a minimum isolation distance of 600 metres is required. |
| The ploidy level turns out to be a very useful complementary criterion for the identification of varieties. |
| These results illustrate that variation exists in maize for the impact of ploidy on gene expression. |
| The male variety should preferably be of the same taxon and at the same ploidy level as the female variety. |
| Leaf size is increased by greater cell ploidy, but the mechanism of this effect is poorly understood. |
| Moreover, by studying the impact of ploidy on salt and water stress tolerance, the researchers revealed that tetraploids were more tolerant. |
