| Background: Haploid plant material is considered as recalcitrant to organogenesis, propagation, and maintenance in vitro. However, sugar beet (Beta vulgaris L.) breeders utilizing doubled haploid (DH) technology in their breeding programs indicate that sugar beet haploids may be cultured in vitro as well as diploids. Thus in this paper the in vitro performance of haploid and the doubled haploid sugar beet of various origin was evaluated. The DHs were derived from haploids by diploidization and twelve such haploid and corresponding DH clone pairs were obtained thus the comparison included haploid and DH clones that had identical allelic composition and differed only in their ploidy level. Results: The genotypes differed in shoot morphology and... |

| Spondias mombin L. shoot cultures were initiated from nodal explants taken from plants propagated by seeds. Explants coming from 4-6 months old plants, previously disinfected, were cultivated on WPM medium supplemented with a wide range of concentrations of BAP (0.0, 0.22, 0.44, 2.22 and 4.44 muM) and NAA (0.0, 0.27 and 2.70 muM). After four weeks, the responses obtained were axillary shoot and root formation. The first response were preferentially induced with the medium containing only BAP, regardless of the BAP concentration. The addition of NAA on medium reduced significantly axillary shoot formation and induced rhizogenesis. Roots were formed on nodal explant basis, preferentially on medium supplemented with 4.44 muM NAA. The medium supplemented with... |
