Root and tuber crops (RTCs) are the second-most important carbohydrate commodity after cereals. Many species of RTCs vegetatively propagated, making their shoot tips preferred material to be conserved for future uses. Shoot tip cryopreservation provides an tool support long-term conservation plant genetic resources. Over past four decades, significant efforts have been undertaken move from rese...

The freshwater polyp Hydra produces buds which separate from the parent. Other Hydrozoa produce branches which remain connected to the parent, thus forming a colony. Some Hydrozoa grow by means of an organ that is like a shoot apical meristem. Others display a sympodial type of growth. In this article, I propose that these different types of branches are organized by a common pattern-forming sy...

An efficient protocol for in vitro clonal propagation of Smilax zeylanica was developed using nodal and shoot tip segments from field grown plants. Nodal explants performed better than when two distinct were tested proliferation. The best results proliferation achieved with MS medium supplemented BAP Kn alone or combination NAA IBA at various concentrations. On containing 4.0 ?M BAP, the greate...

The effect of plant growth regulators on shoot proliferation from shoot tip explants of Ajuga multiflora was studied. The highest number of shoots (17.1) was observed when shoot tip explants were cultured on Murashige and Skoog (MS) medium fortified with 8.0 µM 6-Benzyladenine (BA) and 2.7 µM α-naphthaleneacetic acid (NAA). The mean number of shoots per explant was increased 1.6-fold in liquid ...

The present study demonstrates an efficient protocol for in vitro mass propagation of A. curassavica through direct as well as indirect regeneration. The effect of MS and L2 media supplemented with various concentrations and combinations of growth regulators has been studied. The growth regulators used include BAP and kinetin (cytokinins) and IAA, IBA, NAA and 2, 4-D (auxins). MS media proved b...

Background & Aim: Dracocephalum genus belongs to the Lamiaceae family which has eight species in Iran. Dracocephalum kotschyi Boiss is an important medicinal and aromatic plant that use in pharmaceutical industry. In addition, this species is used in Iranian traditional medicine. The aim of current study was to examine the various growth regulations and explants on direct orga...
