| They hybridise readily in gardens and our nurserymen have had a field day, producing as many as 300 different varieties for us to choose from. |
| Buy seed from reputable seed companies if particular varieties or species are required as aquilegia hybridise easily and may not grow true from seed collected in the garden. |
| Once the genetic sequences have been identified, the EPOBIO researchers will have to select, hybridise or genetically modify the different varieties to arrive at strains that are most suited to biofuel needs. |
| They are a mixture of several species and sub-species – a tribute to the elm's ability to hybridise and give Britain about 40 varieties. |
| A borrowing culture does not hybridise, it digests and appropriates. |
| It is well known that many species of waterfowl can hybridise with each other, and although some cases are due to proximity in wildfowl collections, it is difficult to predict what will happen in the wild. |
