Abstract :
This review article investigates a comprehensive description of the
factors, methods, strategies, approaches and prerequisites influencing in vitro
micropaopagation and the amount of their use across the world. The findings
presented here are the results of the study of several hundred papers published
all over the world. Tissue culture techniques are routinely used for micropropagation.
Enhancement of efficiency and efficacy of plant regeneration are primary goals
of micropropagation. In this article, maximum and minimum use of some basic
issues concerned with plant tissue culture in vitro especially micropropagation
such as types of explants, types of culture media, types of sterilizing agent for
explants, types of plant growth regulators (PGRs) for general studies of miropropagation,
shoot and root induction, somatic embryogenesis (SE) and callus
induction have been considered. Maximal application for explants, culture
media and sterilizing agent are single node, Murashige and Skoog (MS) and
sodium hypochlorite (NAClO), respectively. BA and NAA are the most
application among cytokinins (CKs) and auxins for general studies of miropropagation.
Among all PGRs used for general studies of miropropagation, NAA is
on the top. BA and IBA are the most use among CKs and auxins for shooting
and rooting of explants, respectively. 2,4-D, NAA and TDZ are used more than
the other PGRs for induction of SE. Among all types of auxins and CKs used as
singular or in combination with them for callus induction, 2,4-D is at the top
level. Combination of BA and NAA is the maximum for general studies of
miropropagation. This review article can help to the future studies on micropropagation
due to the correct selection of the treatments.
