Abstract A method was designed to produce rapidly (10–14 days) and directly (without intermediate callus) whole plants of Digitaria sanguinalis with a high yield without subculture. These plants developed from new structures, designated “pseudo-embryogenic structures”, initiated only 1 week after the culture of tranverse thin cell layers (tTCLs), i.e., thin stem sections, on a Murashige and Skoog medium containing 3% sucrose and a combination of a low concentration of 2,4-dichlorophenoxyacetic acid (1 μm) and a high concentration of 6-benzylaminopurine (10 μm). The fresh weight of plants regenerated per tTCL on gelrite was 6 times higher than with agar and 30 times higher than with agarose.
