Other claims from this paper (8)
- Observation Five sunflower genotypes produced no callus or shoots from callus on any medium.
- Observation Three sunflower genotypes showed 80% or more callus formation with little or no shoot organogenesis.
- Observation For four sunflower genotypes, more than 70% of plated embryos developed shoots from callus on one or more media.
- Observation One-half of the sunflower genotypes showed 20% or more shoot-forming callus.
- Intervention effect Medium MS3 gave the most sunflower genotypes with a high frequency of shoot formation from callus.
- Intervention effect Medium MS2 was second in promoting shoot organogenesis from callus.
- Observation A strong genotype x medium interaction affected sunflower shoot regeneration from callus.
- Recommendation Two MS media with different hormonal compositions are recommended to increase the frequency of sunflower genotypes regenerating shoots from callus.
