TL;DR: Trees were produced from firm white callus tissue of triploid quaking aspen initiated on a modified Wolter and Skoog defined medium and subcultured monthly for two years, with mixed results.
Abstract: A B S T R A C T Trees were produced from firm white callus tissue of triploid quaking aspen (Populus tremuloides Michx.), initiated on a modified Wolter and Skoog defined medium and subcultured monthly for two years. When subcultured to medium without auxin, kinetin or supplements, but containing 0.15 mg/liter BAP (6-benzylaminopurine), multiple stunted shoots appeared on most inocula. However, at 0.05 mg/liter BAP, only a few vigorous shoots per piece were initiated, but seven rooted on the callus: two in the dark with BAP and five in 200 ft-c of light with 0.04 mg/liter 2,4-D. After proliferation of the roots on the medium surface, four shoots elongated and were planted in semi-sterilized soil, then were given 3100 ft-c of light for rapid growth into trees. Both light sources were on for 16 hr/day. Two trees were also grown from stunted shoots excised from the callus and rooted in soil. THE INDUCTION of complete plants from cell and tissue cultures of herbaceous angiosperms and monocots was reviewed by Pillai and Hildebrandt

TL;DR: The role of indolylacetic acid (IAA) in influencing the movement of radiophosphorus from a remote locus has been investigated in the decapitated stems of Pisum sativum and disbudded shoots of Populus robusta and the results are discussed in relation to some recently proposed theories concerning the mechanism of translocation in the phloem.
Abstract: The role of indolylacetic acid (IAA) in influencing the movement of radiophosphorus from a remote locus has been investigated in the decapitated stems of Pisum sativum (var. Meteor) and disbudded shoots of Populus robusta. It has been shown after only a few hours that the radioisotope accumulates at the region where the auxin was applied. By steam-girdling experiments with pea, it was established that auxin-induced transport occurs via the phloem and other obserbations suggest that this effect may be independent of growth. When tri-iodobenzoic acid was applied together with IAA at the stump or to the surface of the stem between the IAA source and the injection point of the tracer, the transport of 32P along the stem was greatly reduced. Of a number of auxin-type substances tested, only naphthoxyacetic acid gave a comparable response to that obtained with IAA, whilst other growth regulators such as kinetin or gibberellic acid did not stimulate 32P transport.

TL;DR: High frequency of root induction was obtained due to pulse treatment with a NAA and IBA combination (1:1) at the concentration of 100 mg l−1 for 60 min.
Abstract: The effect of liquid pulse treatment of growth regulators on in vitro propagation of banana (Musa spp. AAA) was studied. Optimal shoot proliferation rates were achieved due to the pulse treatment of 6-benzylaminopurine (BA) and kinetin combination (1:1) at the concentration of 50 mg l −1 for 60 min. Similarly high frequency of root induction was obtained due to pulse treatment with a NAA and IBA combination (1:1) at the concentration of 100 mg l −1 for 60 min.
