Oil Composition of Homozygous and Heterozygous Plants of Citrus Clementina Hort. ex Tan
Tri-haploids have been regenerated through pollen embryogenesis (specifically, by anther culture) of Citrus clementina Hort. ex Tan. cv. Nules. Two of them have been acclimatised and grafted in vivo in 2000. One of them flowered for the first time in the spring 2008. Within the scope of the characterization of these homozygous Clementine genotypes, the essential oils from their leaves and flowers, were analysed and compared with oils obtained from heterozygous plants. The analyses performed evidenced differences not only among the homozygous and the heterozygous plants, but also between the homozygous genotypes. Leaves of heterozygous plant are statistically the biggest for all the parameters considered (leaf weight, size and average surface). Regarding the flower morphometric characters, petal size anther number and ovary diameter were statistically significant larger in flowers from heterozygous mother plant compared with the homozygous one. Moreover, about the essential oil composition, differences were observed not only in the quality of volatile fraction, but also in the quantity; in fact, heterozygous leaves and flowers were characterized by a higher amount of linalool and a smaller of sabinene.
