TL;DR: It is concluded that auxins suppress bud development by stimulating ethylene formation by suppressing the inhibitory actions of ethylene and IAA on bud growth.
Abstract: Indole-3-acetic acid stimulates ethylene production in the nodal region of pea stems, and the gas inhibits bud growth. At all concentrations of IAA there is a close correlation between the intensity and duration of ethylene production and the bud inhibition which results. Kinetin reverses the inhibitory actions of ethylene and IAA on bud growth. It is concluded that auxins suppress bud development by stimulating ethylene formation. The possibility that auxin induced ethylene formation controls apical dominance is considered.

TL;DR: Results indicated that shoots established at 100% regardless of media type, however, shoot height, nodes per shoot, and leaf number were highest for explants established on MS medium compared to NN or B5.

TL;DR: It has been concluded that Kinetin specifically triggers mitosis in mature pea root tissue cells which have undergone DNA- and chromosome-doubling by endomitotic reduplication before kinetin treatment.

TL;DR: It is estimated that by subculture 500 viable plants can be obtained from a single bud of a mature plant or 3000 plants from a seedling in a year.

TL;DR: The role of different cytokinins during in vitro shoot development is brought into focus, discussing their effects on the histology of leaves developed in vitro, and how this affects the subsequent regeneration process.
Abstract: Effective regeneration in vitro is a necessary precondition for the implementation of different biotechnological approaches in plant breeding. Numerous studies have reported on regeneration from apple somatic tissues, and organogenesis has been proved to be influenced by several factors including mother shoots (genotype, size, type, and age of explant), in vitro conditions (dark period, light intensity, and quality), and others (wounding, orientation of leaf explants). However, one of the most important factors before and during the regeneration process is the type and concentration of cytokinin applied. Thidiazuron and benzyladenine are the most frequently used cytokinins in the regeneration systems, but their efficiency depends on genotype and other factors. Other cytokinins (e.g., zeatin and kinetin) have also been tested in several experiments and they were found in general to be less active. The organogenic ability of explants can also be increased by a properly selected cytokinin pre-treatment. Cytokinins applied in the pre-treatments can influence the leaf structure, which in turn can alter the regeneration capacity of the leaf explant. Interactions between factors of pre-treatments (hormones, light, and culture conditions) and factors of the regeneration phase should be considered. This review brings into focus the role of different cytokinins during in vitro shoot development, discussing their effects on the histology of leaves developed in vitro, and how this affects the subsequent regeneration process.
