The cytokinin, N6-benzylaminopurine (BAP), when applied to young inflorescences of wild-type Antirrhinum majus L., resulted in the formation of chimeric "filamentous structures" in the dorsal region of the third whorl, the position where a stamen primordium is suppressed in wild-type flowers. In addition, BAP induced similar filamentous structures in between the first and second whorls, and this response was concentration dependent. The basal region of the filamentous structures was similar to the filament of a stamen, while the distal portion resembled a petal. These observations suggest that

Abstract Nodes from field-grown coppice regrowth and mature trees of Eucalyptus sideroxylon were cultured on a modified Murashige and Skoog medium containing BAP and NAA. BAP (2-4 μm) and NAA (0.5-1.0 μm) were most effective in promoting axillary shoot proliferation from coppice and adult tissues. IBA was more effective than NAA in stimulating the formation of adventitious roots from in vitro-derived shoots. Plantlets from tissue culture were easily transferred to the greenhouse environment.

Addition of the cytokinins, benzylaminopurine, N6-Δ-(2-isopentenyl)-adenine, kinetin, zeatin, and zeatin riboside to a basal medium containing mineral salts and sucrose induced characteristic changes in pollen embryogenesis in cultured anthers and anther segments of Hyoscyamus niger. In anthers cultured in media containing 0.01–10.0 mg/L of each cytokinin, there was a progressive delay in the appearance of plantlets outside the anther locule and in the morphology of plantlets formed. Among the cytokinins tested, only zeatin riboside promoted anther efficiency; however, all compounds reduced po

Hence, the aim of this study was to determine the optimal conditions for the micropropagation of a Begonia montaniformis × Begonia ningmingensis var. bella F1 progeny by using various concentrations of plant growth regulators (PGRs) and varying light spectra in half-strength Murashige and Skoog (1/2 MS) medium. The results showed that the explant regeneration was optimal when the lamina was incubated in a medium supplemented with 2.0 μM N6-benzylaminopurine and 0.8 μM α-naphthaleneacetic acid (NAA)

Jojoba (Simmondsia chinensis L.) oil is also known as liquid wax or fixed oil. It is an important metabolite of jojoba having commercial importance in cosmetics as well as a potential biofuel source. We presented an efficient system for in vitro establishment of cell suspension cultures (CSC) from proliferating friable calluses. For this purpose, cotyledon, internode, and leaf explants were cultured on MS medium + 1, 2, 4, 6, 8 or 10 µM 2, 4-Dichlorophenoxyacetic acid (2, 4-D), α-Naphthalene acetic acid (NAA) alone or in combination with 1 or 2 µM N6-benzylaminopurine (BAP) or Kinetin.

This study compares plant growth regulators’ effects on enhancing propagation efficiency in snapdragon. In the seedling development phase, IP at 1.0 mg L-1 provided the highest germination ratio (91.11 ± 9.30%). The 6-benzylaminopurine (BAP) treatment at 1.0 mg L-1 gave the highest number of shoots (4.42 ± 0.30) whereas the medium with 0.50 mg L-1 IP triggered shoot elongation (3.80 ± 0.28 cm) from germinating seeds.

Explants grown on media containing BAP (0.5–5.0 mg L−1) and zeatin (5.0 mg L−1) produced multiple shoots. The largest number of shoots (≥ 5.0 mm) were obtained with 1.0 mg L−1 BAP. On the basis of useable shoots (≥ 15.0 mm), however, there was no difference in shoot number between 0.5 and 1.0 mg L−1 BAP. With increasing BAP concentration, shoot length decreased, while stem diameter increased. The longest shoots were

Vitex negundo L. is an aromatic, woody, blooming shrub in the Verbenaceae family which can grow into a small tree. Traditionally, V. negundo root has been used to cure diabetes, colic, boils, leprosy, and rheumatism. Keeping the importance of its roots in mind, an attempt has been taken for development of a protocol for efficient hairy root proliferation system. The Agrobacterium rhizogenes strains (MTCC 532 and MTCC 2364) were used for hairy root induction. For A. rhizogenes infection, both in vitro and in vivo leaves as well as internodes were used as explant. In vitro leaves and internodal

The first efficient micropropagation protocol for Phlomis aurea was established as a mean of ex situ conservation of the plant.

Cyphomandra betacea (Cav.) is commonly known as Tamarillo or tree tomato. This species is mainly used for its edible fruits which have a high nutritional value and contain relatively high amounts of proteins, vitamins B6, C, E, and provitamin A. The cultivation of Tamarillo in Rwanda is facing major challenges caused mainly by viral diseases such as Tamarillo mosaic virus (TaMV). These diseases are difficult to control and are transferred through vegetative propagation, often resulting in heavy productivity losses and poor-quality fruits.
