摘要：The 27 lemon cultivars analysed could be considered slightly or moderately polyembryonic, with 25 to 43% of seeds being polyembryonic and from 1.3 to 1.6 embryos per seed. On this basis, it is necessary to rescue zygotic embryos at an immature stage. Rescue and in vitro embryo development have been studied in two Citrus limon polyembryonic cultivars. Sucrose (50 and 70 g/l) was combined with Murashige and Skoog and Gamborg's B5 media and tested for optimal growth response. An important effect of genotype was observed: embryos from cultivar 'Eureka' had greater survival, germination percentage, and radical development. While the sucrose concentration in the medium did not have an effect on germination, the medium affected the embryo survival and root development of the seedlings, Gamborg's B5 medium giving the best results. The ability to form plants in vitro was affected by an increase of embryo developmental stage. The germination and seedling height were greater with embryos of seeds collected 135-150 days after anthesis.
