The genus Begonia under the family Begoniaceae is one of the top ten genera of angiosperms in the world, with 1,550 species and 1,500 hybrids worldwide, and new species are being discovered all the time.

Begoniaceae plants with white flowers
We have obtained a complete system for the
regeneration of Begoniaceae plants in tissue culture,
which provides technical support for their large-scale
production.

Begonia prefers warm and humid environments, is not cold tolerant, and fears direct sunlight. Therefore, its distribution is limited to rainfed, forested areas with high air humidity, such as tropical and subtropical regions of Africa, Central, and South America, and Asia, and a few species are also found in temperate regions.

Most of the species in the Begoniaceae family are ornamental, with beautiful flowers and foliage, and have significant medicinal value. Begoniaceae plants show high diversity in habitat, habitat, sex, physiognomy, leaf shape, and flower color, and even the same species has significant variation in some traits. The germplasm resources and development prospects of Begoniaceae have a series of problems due to various factors such as environmental damage, which need to be paid attention to and solved.

Tissue culture service

For tissue culture of Begoniaceae plants, Lifeasible generally uses MS medium and the carbon source is mostly sucrose.

The addition of different species and phytohormones at different concentrations during the culture process also has different effects on differentiation and growth. In some species, healing tissues can be differentiated on a medium without any growth regulators. We generally use NAA and 6-BA in the culture of Begoniaceae plants. These two phytohormones are significantly more effective than other phytohormones with the same effect, and the concentration and ratio between them can have a significant effect on the culture effect.

The selection of tissue culture material is mostly leaves, petioles, or stem segments, but the contamination rate, mortality rate, and differentiation rate of various explants in the culture process are also somewhat different due to species differences. And Lifeasible successfully used other organs such as fruit as explants for tissue culture and achieved better results, including the use of anthers for culture, and successfully obtained genetically haploid plants. The capsules were sterilized and the leaves of seedlings were sterilely germinated as explants, and the treatment was able to reduce the contamination rate to some extent.
