| Research Abstract |
(1)Long vase life cultivar, 'Miracle Rouge' showed little ethylene production during flower senescence. The level of Dc-ACS1,Dc-ACO1,Dc-EIL3 and Dc-EIL4 in long life cultivar was low compared to control cultivar. The finding suggests that low level of these genes relate to low ethylene production in long vase life carnation. (2) We found a carnation line with ultra-longevity which had vase life of about 30 days. Level of Dc-CPIn gene was different between the line with ultra-longevity and the long life cultivar. In the near future, we will try making the transgenic carnation with modified Dc-CPIn gene expression.
