This 9-minute video describes the protocol used in cassava for the analysis pollen tube grow in vivo. Then images of pollen tube growth taken with a fluorescence microscope are presented to illustrate the process. Finally an overall description of the time required for the pollen tube tip to reac...

This 9-minute video presents images of cassava flowering and its close association with branching. Changes in the shape of the apical meristem before emergence of flowers, female and male flowers and pollination techniques are described in detail. Este video de 9 minutos muestra los eventos más r...

This 14-minute video describes the protocol used for the collection of female flowers at different ages after anthesis and the development of a protocol of early embryo rescue. The production of doubled haploids through different gynogenesis approaches usually require an early rescue of embryos w...

This 9-minute video describes the protocol used for the collection of male flowers in cassava for the production of doubled haploids through androgenesis (in vitro microspore or anther culture). Pre-treatments and different culture conditions used in the process to induce cell division in immatur...
