In Vitro Bulb Production in Hippeastrum (Hippeastrum Hybridum)

Abstract

An in vitro experiment was conducted to find out the optimum hormonal supplement and sucrose level for the bulb production of Hippeastrum. Murashige and Skoog medium supplemented with different hormone concentrations of BAP (0.0, 2.0, 4.0, 6.0 and 8.0 mg/L) and CCC (0.0, 125, 250 and 500 mg/L) and sucrose levels (30, 60, 80, 90 and 110 g/L) were used in this study. Sucrose level at 90 g/L produced the maximum average weight as well as the highest regeneration percentage. The increasing rate of CCC increased the number and average weight of bulb. The maximum bulb formation observed in media supplement with 6.0 mg/L BAP and 500 mg/L CCC fortified with 90 g/L sucrose.

Revealing the complex genetic structure of cultivated amaryllis (Hippeastrum hybridum) using transcriptome-derived microsatellite markers

“…Amaryllis have attracted worldwide attention given their large size, variety of brightly coloured and long-lasting flowers 7 , and greater than 300 cultivars are currently recognized 5 . Varieties of Hippeastrum are exported by the Netherlands, South Africa, Japan, Brazil, and the United States 8 and can be traced back to a breeding plan initiated in 1799 9 that was based on a simple F 1 hybrid between Hippeastrum .…”

Contamination of locally produced herbal medicine sold in Gombe main market with selected pathogenic bacteria

“…MacConkey agar and Nutrient agar were used for bacterial isolation. The agar mediums that usually used by other authors (Sultana et al 2010;Siddique et al 2006) were not tried for this experiment.…”
