Seed and Seedling Vigour in Tropical Maize Inbred Lines

Variability among maize inbred lines for seed longevity

Genotypic Variation in Seedling Tolerance to Aluminum Toxicity in Historical Maize Inbred Lines of Zambia

Maize (Zea mays L) is the most important food grain in sub-Saharan Africa and is mostly grown by small-scale farmers under rainfed conditions. Aluminum toxicity caused by low pH is one of the abiotic factors limiting maize production among smallholder farmers. Therefore, breeding maize hybrids that are tolerant to aluminum toxicity will sustain and increase maize production in these areas. Henc...

Karyotype variability in tropical maize sister inbred lines and hybrids compared with KYS standard line

Maize karyotype variability has been extensively investigated. The identification of maize somatic and pachytene chromosomes has improved with the development of fluorescence in situ hybridization (FISH) using tandemly repeated DNA sequences as probes. We identified the somatic chromosomes of sister inbred lines that were derived from a tropical flint maize population (Jac Duro [JD]), and hybri...

Effect of pre-sowing treatment on seed germination and seedling vigour in endive and chicory

The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory was examined. Halopriming (KNO3) or growth regulators (gibberelic acid; GA3) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing t...
