MS (Murashige and Skoog) media supplemented with benzylaminopurine (BAP) showed that the number of bud formation in shoot cultures of Musa acuminata cv.Berangan during the initiation stage increased proportionately with the concentrations used (11, 22 and 33 μM). However, the highest concentration of BAP (33 μM) simultaneously increased the formation of abnormal shoots. After the first apical b...

Apical meristems, first, second and third-fourth axillary buds of Ludwigia repens were cultured on Murashige and Skoog (MS) medium containing various concentrations of 6-benzylaminopurine (BAP), thidiazuron (TDZ) and αnaphthaleneacetic acid (NAA) for micropropagation. Micropropagation was best achieved from apical meristem on MS medium containing 0.05 mg dm TDZ and 0.1 mg dm NAA. It was noted t...

An efficient protocol has been developed for regeneration of complete plants through somatic embryogenesis in H. coronarium. Creamish white, pale yellow and brown calli were obtained on MS medium supplemented with different concentrations of auxins [2, 4-Dichlorophenoxy acetic acid (2, 4-D), Indole-3 acetic acid (IAA) and 1-Naphthylacetic acid (NAA)] after 4 weeks. Creamy white calli developed ...

The plant hormones cytokinins (CKs) regulate multiple developmental and physiological processes in Arabidopsis (Arabidopsis thaliana). Responses to CKs vary in different organs and tissues (e.g. the response to CKs has been shown to be opposite in shoot and root samples). However, the tissue-specific targets of CKs and the mechanisms underlying such specificity remain largely unclear. Here, we ...

The objective of this work was to optimize in vitro plant regeneration via organogenesis from tissues of adult 'Hamlin', 'Pêra', and 'Valência' sweet orange plants. Explants were grown in EME culture medium with different concentrations of 6-benzylaminopurine (BAP) and naphthaleneacetic acid (NAA), at 27oC in the absence of light for 50 days, followed by a 16-hour photoperiod for 20 days. Regen...

Aim. The effect of chronic ultraviolet B (UV-B) radiation and cytokinin benzylaminopurine (6-BAP) on the growth, content photosynthetic pigments hydrogen peroxide (HP) in leaves pea plants (Pisum sativum L.) was studied. Methods. Pea cultivar Gotivsky were irradiated by UV-B at a dose 3.5 kJ/m2 per day during 5 days. Groups non-irradiated treated with 6-BAP after end radiation. Length shoots ro...

Efficient in vitro plantlet regeneration is an important step to successfully transform genes for the improvement of agronomic traits. A combination 6-benzylaminopurine (BAP) and thidiazuron (TDZ) plant growth regulators was applied evaluate shoot capacity whereas α-naphthalene acetic acid (NAA) with (BAP), 2, 4-dichlorophenoxyacetic (2, 4-D) were tested optimize root induction two peanut culti...

Embryogenic cultures of Picea balfouriana, which is an important commercial species for reforestation in Southern China, easily lose their embryogenic ability during long-term culture. Embryogenic tissue that proliferated at lower concentrations (3.6 μM and 2.5 μM) of 6-benzylaminopurine (6-BAP) were more productive, and generated 113 ± 6 and 89 ± 3 mature embryos per 100 mg embryogenic tissue,...
