Abstract:

The experimentations were performed during

2011-2012 in Laboratory of Plant Tissue Culture

from Vegetable Research and Development Station

Bacau.

Regeneration, in all its aspects – callus, shoot

and embryo formation and rooting of newly formed

plantlets are key points on which relies the entire

concept of in vitro tissue culture.

Therefore, the main objective of the present

study was the assessment callus and shoot induction

in white cabbage anthers cultivated on media with

different concentration and combination of PGRs.

Anther-derived calluses, normally

accompanied by elongating small buds, are induced

in response to type of auxins added and subsequently

to combination with cytokinin, especially 6-

benzylaminopurine (BA).

The formation of callus structure was the

predominant morphogenetic reaction on media with

2,4 D, while NAA improved the embryogenic

competence of anthers.

The results of the present study also support

the idea of major impact involvement of PGRs in the

expression of cells totipotence.

Keywords:

organogenesis, embryogenesis, regeneration, cabbage.
