He was involved in experiments to hybridise crosses were the first scientifically created examples in Australia. 25. Narcissus species hybridise readily, although the fertility of the offspring will depend on the parental relationship. 26. The two species have been extensively cultivated and hybridised to produce a number of popular garden plants. 27. In the second step, two sequence specific primers hybridise to each border of the DNA template. 28. It has been observed to hybridise with introduced " Dianthus barbatus ", when native. 29. Bent's rule provides a qualitative estimate as to how these hybridised orbitals should be constructed. 30. They were created by cross-breeding two types of roses, initially by hybridising tea roses.
