The Influence of Developmental Stages of Haploid and Diploid Callus Cultures of Datura innoxia on Shoot Initiation

Summary The formation of shoots in explants and callus material of Datura innoxia of haploid and diploid origin was initiated by kinetin after various preculture periods on a medium supplemented with 2,4 D. Shoot initiation in haploid material preceds that in diploids.
