Abstract

Apricot (Prunus armeniaca L.) embryos at three stages of development were cultured on C2d, SBH and WPM media. In vitro culture produced high percentages of germination and seedlings throughout all three developmental stages. Significant media effects were noted for changes in both embryo length and weight during the culture period, as well as number of plants produced. Embryos between 5 and 9 mm (developmental stage I) germinated and developed into plants in a significantly higher percentage than in the other two more mature stages. Therefore, embryo culture can be successfully used as a tool in an apricot breeding program to obtain higher percentages of seedlings from planned hybridization or to overcome a lack of seed germination.
