Metabolism of Flavonoids in Novel Banana Germplasm during Fruit Development
Banana is a commercially important fruit, but its flavonoid composition and characteristics has not been well studied in detail. In the present study, the metabolism of flavonoids was investigated in banana pulp during the entire developmental period of fruit. 'Xiangfen 1,' a novel flavonoid-rich banana germplasm, was studied with 'Brazil' serving as a control. In both varieties, flavonoids wer...
متن کاملDiversifying sunflower germplasm by integration and mapping of a novel male fertility restoration gene.
The combination of a single cytoplasmic male-sterile (CMS) PET-1 and the corresponding fertility restoration (Rf) gene Rf1 is used for commercial hybrid sunflower (Helianthus annuus L., 2n = 34) seed production worldwide. A new CMS line 514A was recently developed with H. tuberosus cytoplasm. However, 33 maintainers and restorers for CMS PET-1 and 20 additional tester lines failed to restore th...
متن کاملDeterminants of Banana Productivity and Technical Efficiency in Uganda
This chapter analyzes the technical efficiency of banana production among Ugandan smallholders by estimating a stochastic production frontier model with inefficiency effects. The empirical models are formulated within the overarching framework of the agricultural household specified in Chapter 2. The data design is also summarized in Chapter 2, although additional information about soil quality...
متن کاملCauses of High Fertility in Western Uganda
Fertility rates in other developing regions have continuously declined, except subSaharan Africa, with the fastest population growth (5.2 children per woman – WDI, 2004); this is so, despite high mortality levels due to AIDS pandemics, decline in per capita income and the relatively high contraceptive availability and knowledge. This pattern of events has consequently, reduced productivity and ...
متن کاملIncreased male fertility using fertility-related biomarkers
Conventional semen analyses are used to evaluate male factor fertility/infertility in humans and other animals. However, their clinical value remains controversial. Therefore, new tools that more accurately assess male fertility based on sperm function and fertilization mechanism are of interest worldwide. While protein markers in spermatozoa that might help differentiate fertile and infertile ...
