Conteúdo: |
Somatic embryogenesis in cotton lias been previously reported in a limited number of genotypes, predominantly Coker cultivars. Before tissue culture techniques are widely applied to cotton improvement prograins, regeneration must be possible for a broad range of genotypes. The Mm of the present work was to develop a method to obtain somatic embryoids of an early cotton cultivar (Gossypium hirsutum L. race lar ifolium Hutch cv. CNPA Precoce 2) and their subsequent development. Calius induction was attempted with cotyledon and hypocotyl explants. These explants were cultured on MS medium supplemented with tive concentrations of 2,4-dichlorophenoxyacetic acid (2,4-13) and N6-(2-isopentenyi)-adenine (2iP) either alone or in combination. Based on cailus appearance (light brown and granular), four different growth regulator combinations were selected for further cailus development. Callus was subcultured on 2.45 uM 2iP and subsequently transferred to 0.45 and 22.50 tiM 2,4-D. Somatic embryos of different sizes and shapes subsequently appeared on MS medium supplemented with 2 g L» glutamine and no growth regulators. Plantlets were developed from those embryoids. Plant regeneration through somatic embryogenesis is achieved for fite first time in the early cultivar CNPA Precoce 2. |

The use of sugarcane silage is a feasible option for shortage of forage in pastures, increasing the losses during the fermentation process. However, the use of additives is required due to the high level of soluble carbohydrates, as well as the large number of yeasts that promote alcoholic fermentation with high CO2 production, increasing losses during the fermentation process. This experiment aimed to evaluate the effects of calcium oxide and crude glycerin on the chemical composition of sugarcane silage. |
