TLDR
Shoot multiplication was achieved in vitro from shoot tips of aseptically germinated seedlings of Withania somnifera L. with direct multiple shoot initiation from germinating seeds in the presence of BA alone.
Abstract
Shoot multiplication was achieved in vitro from shoot tips of aseptically germinated seedlings of Withania somnifera L. using low concentrations of 6-benzyladenine (BA), viz. 2.2, 4.4 and 8.9 μM. Maximum number of shoots were obtained when 2.3 μM 2,4-dichlorophenoxyacetic acid (2,4-D) or 2.5 μM indolebutyric acid (IBA) was added to medium containing 4.4 μM BA during initiation of shoot multiplication, but not when added later. Direct multiple shoot initiation was also obtained from germinating seeds in the presence of BA alone. Rooting was successful in excised shoots grown on growth regulator-free MS medium. Rooted shoots were successfully established in soil in a greenhouse.

Photon flux density and light quality induce changes in growth, stomatal development, photosynthesis and transpiration of Withania Somnifera (L.) Dunal. plantlets

TL;DR: Both the quality and the quantity of light affect growth of plantlets, development of stomata and physiological responses differently depending on the intensity and the wavelength of light.

Micropropagation of Vitex negundo L., a woody aromatic medicinal shrub, through high-frequency axillary shoot proliferation.

TL;DR: Although callus-free multiple-shoot formation was a function of cytokinin activity alone, faster bud break coupled with an enhanced frequency of shoot development and internode elongation were dependent on the synergistic influence of gibberellic acid (GA3) along with BA when used at an optimal concentration.

In vitro propagation of the medicinal herbs Ocimum americanum L. syn. O. canum Sims. (hoary basil) and Ocimum sanctum L. (holy basil).

TL;DR: A procedure is outlined for in vitro propagation of two medicinal herbs, OCimum americanum L. canum Sims (hoary basil) and Ocimum sanctum L.'souvenir (holy basil), using axillary shoot buds using benzyladenine supplemented with BA to induce multiple shoot formation.

In vitro callus induction and regeneration studies in Withania somnifera

TL;DR: Callus cultures were initiated from axillary leaves, axillary shoots, hypocotyls, and root segments on Murashige and Skoog medium supplemented with 2,4-D and KN to establish axillary shoot base callus on MS medium containing BA.

Chemistry and genetics of withanolides in Withania somnifera hybrids

TL;DR: In this paper, the inheritance characteristics of various substituents on the withanolide skeleton were analyzed based on the occurrence in per cent of each substituent in relation to the total withanolides content in the hybrid plants and their respective parents.

Factors affecting in vitro proliferation and rooting of shoots of jackfruit ( Artocarpus heterophyllus Lam.)

TL;DR: Of the cytokinins tested, benzylaminopurine (BAP) was more effective than either 2-isopentenyladenine (2iP) or kinetin (Kin) and produced maximum proliferation when used at 5×10-6M.
