Leaf discs of Nicotiana rustica L. were floated on NaCl in the presence of kinetin or abscisic acid. On the 5th day (14)CO(2) fixation, [(3)H]leucine incorporation, stomatal conductance, and chlorophyll content were determined. Kinetin either partially or completely reversed the inhibitory effects of NaCl while ABA had no effect.
A bstract. Kinetin in concentrations of 10-e to 10-4 M, stimuated ethylene production in 3 and 4-day old etiolated seedlings of Alaska pea (Pisucm sativum L. var. Ala-ka). Seedlings of other species responded similarly. The response to kinetin depended on the age of the seedlings. Kinetin alone did not influence ethylene production in 6-day old stem sections, but it greatly increased the enhanc...
Effect of cadmium on barley seeds treated with kinetin and gibberellic acid was investigated. As usual, cadmium has inhibited seed germination, and showed important inhibitory effects on roots and coleoptile growth after germination. In general, increase in cadmium concentration caused a greater inhibition of germination, root and coleoptile growth. The adverse effect of cadmium on root and col...
A technique which incorporates a brief blending step to disperse callus tissue into small clumps of cells was developed, and the effects of cytokinins on respiration of soybean (Glycine max [L.] Merrill var. Acme) callus tissue prepared in this way were studied. Adenine alone did not affect respiration, but kinetin and zeatin showed effects correlating with their reported effects on growth of t...
We analysed the level of polyamines (PAs) bound to thylakoids and the level and activity of thylakoid transglutaminases throughout barley leaf senescence, retarded by kinetin. The level of PAs bound to thylakoids changed in senescing barley leaves: bound putrescine (PU) and spermidine (SD) increased throughout senescence, whereas bound spermine (SM) decreased. Kinetin diminished the increase in...
The influence of the synthetic phenylurea cytokinin 4-PU-30 and of the adenin cytokinin kinetin on the chilling and freezing stress of tobacco callus was studied histochemically. The investigations were carried out immediately after the low-temperature stress and after 20 days cultivation. It was established that alcohol dehydrogenase and glutamate dehydrogenase activities decreased but esteras...
Kinetin induces formation of red pigment in seedlings of Amaranthus retroflexus in the dark. This effect is similar to the light-induced formation of pigment. Light and kinetin do not act in a simple additive way. The pigment is not an anthocyanin, and its formation is not affected by inhibitors of anthocyanin formation.
This study aims to observe the growth in sprouting phase and sulforaphane content stages of broccoli sprouts treated with kinetin on MS media. The research was conducted at Laboratory Biotechnology, Faculty Agriculture, Sam Ratulangi University Department Chemical Engineering, State Malang. used a Completely Randomized Design (CRD) 4 treatments 9 replications, nam ely without kinetin, 0.5 ppm 1...
Received: Revised: Accepted: The molecular mechanisms specifying anti-oxidative and anti-aging action of kinetin (Kn) on the splenic oxidative damage of aging rats are poorly understood. Here, the Sprague Dawley (SD) rats (Rattus norregicus) aging model was proposed by napes subcutaneous injection of D-galactose, and anti-aging group were subsequently dealt with doses of 5, 10, 20 mg/kg·BW of K...
