Photoperiod Effects On 2n Pollen Production, Response To Anther Culture, And Net Photosynthesis Of A Diplandrous Clone Of Solanum Phureja, Henry R. Owen, R. E. Veilleux, F. L. Haynes, K. G. Haynes

Faculty Research & Creative Activity
Flow-cytometric analysis of pollen samples obtained from Solanum phureja, clone PP5, grown under 10, 14, and 18 hour photoperiods at the Southeastern Plant Environment Laboratories of North Carolina State University yielded two populations of pollen based on size parameters. These populations corresponded to pollen separation based on propidium iodide staining of DNA. Anther culture response from plants grown under 14 and 18 hour photo periods for 8, I 0, 12, and 14 weeks was greatest from 8 week old plants grown under a 14 hour photoperiod. Net photosynthesis was significantly higher for plants grown under a 10 hour photoperiod than …
Variability For Critical Photoperiod For Tuberization And Tuber Yield Among Monoploid, Anther-Derived Genotypes Of Solanum Phureja, Henry R. Owen, R. E. Veilleux, F. L. Haynes, K. G. Haynes
Variability For Critical Photoperiod For Tuberization And Tuber Yield Among Monoploid, Anther-Derived Genotypes Of Solanum Phureja, Henry R. Owen, R. E. Veilleux, F. L. Haynes, K. G. Haynes
Faculty Research & Creative Activity
Monoploid genotypes (2n = x = 12), derived by anther culture of a diplandrous (2n pollen-producing) clone of Solanum phureja Juz. & Buk., a South American diploid potato species, were examined for their use in germplasm development. Nine monoploid genotypes and the anther-donor genotype were grown in three chambers (10-, 14-, and 18-hr daylengths) to examine the effect of photoperiod on tuber yield and to determine the variability for critical photoperiod for tuberization. Significant differences were found among the monoploid genotypes for tuber weight and tuber number. Longer photoperiod treatments decreased and delayed tuberization. Axillary tuber formation from single-node cuttings …
Environmental, Genotypic, And Ploidy Effects On Endopolyploidization Within A Genotype Of Solanum Phureja And Its Derivatives, Henry R. Owen, R. E. Veilleux, D. Levy, D. L. Ochs
Environmental, Genotypic, And Ploidy Effects On Endopolyploidization Within A Genotype Of Solanum Phureja And Its Derivatives, Henry R. Owen, R. E. Veilleux, D. Levy, D. L. Ochs
Faculty Research & Creative Activity
Flow-cytometric analyses of DNA content were performed on chopped in vivo, in vitro, and protoplast-derived in vitro nuclei of Solanum phureja. An anther-derived monoploid genotype and a diploid and tetraploid clone, derived from callus culture of the monoploid genotype, were used to characterize the influence of in vivo and in vitro environment and explant ploidy level on the extent of endopolyploidization. In addition, protoplast-derived nuclei, from nine anther-derived monoploid genotypes, were examined for genotypic influences on endopolyploidization. DNA distributions of the anther-derived monoploid and callus-derived clones in vivo contained peaks corresponding to 1C, 2C, and 4C DNA levels. By comparison, …
