Abstract Sugar beet ( Beta vulgaris L.) is referred to as a strategic species due its exceptional economic and functional importance. cultivated in order provide material for sugar production it the world’s second source after cane. However, this species, regeneration of haploid shoots difficult comparison other cultures or isolated microspores. Haploid plants can be derived from vitro culture ...

PREMISE OF THE STUDY Chloraea crispa is a terrestrial Orchidaceae species native to Chile, characterized by a beautiful and showy inflorescence. The species has a great potential for commercial exploitation in the cut flower industry, but it is essential to improve propagation methods to avoid endangering its natural populations. Because this species is hard to propagate using traditional green...

(Prague), 38: 27–34. The effects of temperature pre-treatment, thidiazuron, naphthaleneacetic acid, and 6-benzylaminopurine on in vitro gynogenic plant production from un-pollinated melon (Cucumis melo L.) ovaries w...

The influence of explant nodal positions on the in vitro shoot growth and proliferation were studied in the two rose cvs. ‘Bianca’ and ‘El Torro’. Third, fourth and fifth nodal explants were cultured on the modified MS medium supplemented with 1.0 and 5.0 mg/l BA. In both the cultivars, higher rate of proliferation (‘Bianca’ 3.75; ‘El Torro’ 2.65) were obtained from the explants distal to the a...

One of the main obstacles in providing quality potato seed tubers is long dormancy period seeds. A study that explores this has been carried out to elucidate response release and initiation sprouts differences tuber weight storage duration before immersion cytokinin (6-benzylaminopurine). The was conducted at warehouse UPT Horticulture Parent Seed Kutagadung Berastagi, Department Food North Sum...

We examined the effects of some cytokinins and cytokinin ribosides including a series of adenosine analogs differently substituted in the N(6) position, along with some hypoxanthine derivatives on the viability of normal and neoplastic human cells. Cytokinins such as trans-zeatin, isopentenyladenine and benzyladenine do not show any effect, while cytokinin ribosides such as trans-zeatin ribosid...

A cytokinin-binding protein has been isolated from wheat germ via ammonium sulfate precipitation, carboxymethyl Sephadex chromatography, and affinity chromatography on a column substituted with a derivative of kinetin riboside. On Sephadex G-200, the protein migrated with an apparent molecular weight of 122,000 daltons. The dissociation constant for kinetin was determined by equilibrium dialysi...
