The given plant, Solanum tuberosum was grown in the field as well as in petri plants by seeds.The different explants such as leaf, node, internodes, bud and roots were taken for micropropagation. These explants were grown in vitro after thorough sterilization using different PGR in different media composition.The PGR used were 2,4-D, BAP and NAA. Their combination were also used i.e. 2,4-D+BAP, BAP+NAA and 2,4-D+NAA in different concentration.The most effective and suitable media composition was MS (Murashige & Skoog, 1962) basal medium with BAP (2.0 mg/l) for regeneration from nodal explant...

Solanum nigrum was initially grown, in the soil through seeds, and also in the petri dishes. For the purpose of micropropagation, MS basal medium was used along with different PGRs i.e, BAP, 2,4-D, NAA and their different combinations. Effects of different physical and chemical factors on the in vitro growth of these explants were studied. As far as, physical factors were concerned, it was noted that 22 2 C for in vitro growth of Solanum nigrum was used. It was also observed that the micropropagation of Solanum nigrum in liquid medium gave only 5% in vitro growth. Whereas, solidified medium...

The present study deals with the callogenesis and micropropagation of grapes (Vitis vinifera L.) and biochemical investigation of protein content and peroxidase activity during different stages of growth. In the protocol of micropropagation, four different types of media with different concentration of auxin, cytokinin and their combinations were used. Best result was obtained with the TDZ 25.0 (uM) with 90% frequency rate. In the induction of callogenesis procedure, three different types of media concentration of auxin, cytokinin and their combination were used with leaf and node as explant....
