Maturation in conifers includes several distinct and persistent changes in the growth habits of apical meristems. Despite many studies on maturation in conifers, there are still many aspects of the process that have not been elucidated.

The converse has been, and still is, common practice. It is true that the regenerative potential of plants, which is indeed impressive, sets them apart from the more familiar animal...

A novel protocol for production of multiple shoot tip clumps of Keelar nelli (Phyllanthus amarus Schum. & Thom.) were developed in vitro from shoot tip explants cultured on Murashige and Skoog (MS) medium containing only BAP or BAP with NAA, 3% sucrose and 0.8% agar. The addition of the following combination of growth substances 0.1mgLBAP and 0.05mgLNAA, caused an extensive proliferation of mul...
