Regeneration and evaluation of first and second cycle somaclones of 'Thornless Evergreen' blackberry (Rubus laciniatus) Willd.)
… (Rubus laciniatus Willd.) using thidiazuron (TDZ) and naphthaleneacetic acid. TDZ was superior to benzylaminopurine (BA) in promoting adventitious shoot formation on in vitro-grown TE leaves. TDZ was active at lower concentrations than BA and stimulated adventitious shoot formation from …

Cytokinins tolerance and in vitro selection for dwarfism in apple (Malus x domestica Borkh.)
… with N-phenyl-N$\sp\prime$ 1,2,3,-Thidiazuron (TDZ). TDZ was found superior to benzylaminopurine (BAP) in promoting adventitious shoot formation. The optimum levels of TDZ ranged from 2 to 4 $\mu$M whereas, the optimum levels of BAP occurred between 4 to 12 $\mu$M depending on cultivar. …

Development of improved solutions for steel catenary riser challenges
… and fatigue challenge of the conventional SCR TDZ. Under limited environmental conditions and vessel motion, a small diameter pipe performs better in strength and fatigue response around the touchdown zone (TDZ) than a larger diameter riser pipe. However, the large bore pipe provides benefits …

Development of in vitro regeneration and gene transfer systems for conifer species
… of genotype and various cytokinins (BA, BPA, and TDZ) in combination with 2,4-D were investigated. Among the cytokinins tested, 20 $\mu$M BPA with 5 $\mu$M 2,4-D produced the highest frequency of shoot organogenesis from three genotypes while, 10 $\mu$M TDZ with 5 $\mu$M 2,4-D produced the highest …

Efecto de diferentes concentraciones de sacarosa y citoquininas de síntesis en la propagación in vitro de un híbrido de alstroemeria (19a01)
… con el regulador de crecimiento tidiazurón (TDZ) (0,0; 0,5; 1,0 y 2,0 mg L-1) sobre la eficiencia de multiplicación del híbrido de alstroemeria 19A01. Se evaluó a las 3, 6 y 9 semanas del inicio del experimento el peso de explante (g), largo de rizoma (cm), largo de brote (cm), número de …

In vitro separation of chimeral pears into their component genotypes
… The effect of different levels of Thiadizuron (TDZ) and Naphthaleneacetic acid (NAA) on shoot regeneration was investigated. Among the different levels of TDZ used, a range of 3 to 7 uM was optimum for most cultivars, while a level of 4.5 to 5 uM NAA gave the best regeneration for the two …

In vitro micropropagation, evaluation of disease resistance and hardiness of several new rose cultivars
… medium supplemented with combinations of BA and TDZ. Leaves and roots of 'Carefree Beauty', 'Prairie Youth' and 'John Frobisher' failed to regenerate shoots in vitro.

Maximizing and minimizing pear (Pyrus sp.) chimeral segregation in vitro
… and segregation were growth regulators (TDZ and BA), medium type, and selection at subculture. The pear chimeral cultivars used in this study showed differential responses to some of these factors. 'LB' chimera was a less stable cultivar than 'RC' and 'RH'; red 'RH' was the most stable …

Biolistic-mediated transformation of Eragrostis Curvula with the HSP 12 gene
… supplemented with either 0.5 mg/I thidiazuron (TDZ) or 0.5 mg/I 6-benzylaminopurine (BAP) through the process of direct organogenesis. It was found that TDZ was the most effective cytokinin. Plant regeneration was also achieved from callus induced from immature leaves on MS medium supplemented …

A microculture approach towards enhanced productivity and genetic improvement of pecan (Carya illinoensis)
… initiation and long-term shoot development. TDZ at 25 $\mu$M produced somatic embryos and adventitious buds. Sixty-one percent of the excised cultured cotyledon segments formed adventitious roots at 50 $\mu$M NAA. Axillary buds on microcuttings were induced to grow only when media were …

Improved regeneration and Agrobacterium-mediated transformation of wild strawberry (Fragaria vesca L.)
… explants were exposed to varying durations on TDZ containing medium during shoot regeneration. The transformation efficiency was given as the mean number of GFP+ plants obtained per primary explant cultured. Multiplex PCR, for amplification of the hptII and GFP genes, was performed on a random …

Az in vitro szaporítás hatékonyságának fokozását célzó eljárások alakalmazása kertészeti növényeken
… citokininek (kinetin, 2iP, BAP, zeatin, TDZ) hatását vizsgáltuk a hajtáscsúcsból, valamint levél-, levélnyél-, internódium- és gyökér darabokból történő hajtásindukció folyamatában Atropa belladonna és Populus alba tenyészetekben. A leghatékonyabb citokinin ill. ennek optimális …
