| chromatographic analysis of a cytokinin from tissue cultures of crown-gall. | extracts from tissue cultures of crown-gall from parthenocissus tricuspidata (sieb. and zucc.) planch. exhibited cell division activity in the soybean cytokinin assay. the chromatographic migration of one component, responsible for most of the activity, is similar to that of zeatin ribonucleoside. in addition, acid hydrolysis of the active region taken from chromatograms and of an eluate from a cation-exchange resin column resulted in the production of an active free-base-like derivative. since ... | 1971 | 16657664 |
| screening of novel low-cost adsorbents from agricultural residues to remove ammonia nitrogen from aqueous solution. | most studies on ammonia adsorption from aqueous solution have been focused on mineral materials. however, a series of batch experiments were performed in this study to screen novel adsorbent materials from 80 agricultural residues, and to investigate the adsorption characteristics of six screened samples. the results showed that the ammonia adsorption efficiencies of 11 agricultural residues were comparable to those of minerals. the equilibrium data fitted well with both the langmuir and freundl ... | 2010 | 20189302 |

| [ultrastructural aspects of parthenocissus tricuspidata (planch.) (vitaceae) "callus" kept in solid cultures (author's transl)]. | the normal strain shows undifferentiated chloroplasts in opposition to the very well chlorophyllated "callus" which shows all the normal ultrastructural characteristics of the various organelles. the strain which has lost completely the capacity of chlorophyl synthesis shows a remarkable increase in the size and number of mitochondria. the tumor tissue shows deep lobulation in its nuclei as well as undifferentiated plastids in the cytoplasm. an increase of the smooth endoplasmic reticulum in the ... | 1975 | 1236056 |
| adsorption behavior of ammonium by a bioadsorbent--boston ivy leaf powder. | the adsorption behaviors of ammonium ions from aqueous solution by a novel bioadsorbent, the boston ivy (parthenocissus tricuspidata) leaf powder (bptl) were investigated. the sem images and ft-ir spectra were used to characterize bptl. the mathematical models were used to analyze the adsorption kinetics and isotherms. the optimum ph range for ammonium adsorption by bptl was found to be 5-10. the adsorption reached equilibrium at 14 hr, and the kinetic data were well fitted by the logistic model ... | 2010 | 21235179 |
| quantifying the attachment strength of climbing plants: a new approach. | in order to grow vertically, it is essential for climbing plants to firmly attach to their supporting structures. in climbing plants, different strategies for permanent attachment can be distinguished. besides twining stems and tendrils, many plants use attachment pads or attachment roots for this purpose. using a novel custom-built tensile testing setup, the mechanical properties of different permanent attachment structures of self-clinging plant species were investigated, namely the attachment ... | 2010 | 19818882 |
| antimalarial activity of a new stilbene glycoside from parthenocissus tricuspidata in mice. | a novel stilbene glycoside [piceid-(1-->6)-beta-d-glucopyranoside; pbg] from parthenocissus tricuspidata was tested in vivo against plasmodium berghei. pbg exhibited significant blood schizontocidal activity in a 4-day early infection, a repository evaluation, and an established infection, with a significant mean survival time comparable to that obtained with the standard drug, chloroquine (5 mg x kg(-1) x day(-1)). | 2008 | 18625780 |
| [effects of nitrogen supply on parthenocissus tricuspidata seedling morphology and nitrogen allocation]. | with hydroponic culture, this paper studied the effects of different nitrogen (n) supply levels (0, 0.15, 0.3, 0.45, 0.6, 0.75 g n x l(-1)) on the seedling morphology and n allocation of parthenocissus tricuspidata. the results showed that lower n supply retarded the development of p. tricuspidata seedling's branch; while higher n supply had significant effects in promoting the seedling's early branching and lowering the branching position on the main stem. supplying higher amount of n increased ... | 2007 | 18163300 |
| antiplasmodial activity of novel stilbene derivatives isolated from parthenocissus tricuspidata from south korea. | new stilbene glycoside, piceid-(1-->6)-beta-d -glucopyranoside (compound 2, fig. 1), was isolated from the meoh extract of the leaves of parthenocissus tricuspidata (vitaceae) together with four known compounds, piceid (compound 1, fig. 1), resveratrol (compound 3, fig. 1), longistylin a (compound 4, fig. 1), and longistylin c (compound 5, fig. 1). their structures were determined spectroscopically, particularly by 2d nuclear magnetic resonance (nmr) spectroscopic and chemical analysis. the anti ... | 2007 | 17211658 |
| metabolism of indole-3-acetic acid: iii. identification of metabolites isolated from crown gall callus tissue. | the metabolism of labeled indole-3-acetic acid (iaa-2-(14)c) was investigated in parthenocissus tricuspidata crown gall callus tissue. after 48 hours incubation, 85 to 90% of the supplied iaa was taken up by the tissue, and of that taken up, about 45% was conjugated with five amino acids. the conjugates found were aspartic and glutamic acid (minor ones) as well as glycine, alanine, and valine (major ones). the last four are being reported for the first time as metabolites of iaa. these conjugate ... | 1976 | 16659740 |
| two new antioxidant stilbene dimers, parthenostilbenins a and b from parthenocissus tricuspidata. | the ethyl acetate fraction of an aqueous alcoholic extract from the stem of parthenocissus tricuspidata yielded 11 known compounds (1-11) and two new stilbene dimers parthenostilbenins a (12) and b (13) upon purification either by preparative tlc or reversed phase hplc. the structures of the new isolates were identified using a combination of fab-ms and nmr. these compounds were assessed for antioxidant activities in three different bioassay systems. among them, piceatannol showed the strongest ... | 2005 | 16254835 |

| metabolism of indole-3-acetic acid: ii. oxindole pathway in parthenocissus tricuspidata crown-gall tissue cultures. | an indoleacetic acid oxidase preparation from an acetone powder of parthenocissus tricuspidata crown-gall tissue has been examined. an intermediate in the reaction is 3-hydroxymethyloxindole and nonenzymic conversion of it to 3-methyleneoxindole was observed. neither reaction mixtures nor 3-methyleneoxindole have any auxin-like activity in avena or wheat coleoptile bioassays. in vivo studies show that although 53% decarboxylation of indoleacetic acid was observed in 48 hours, only a small amount ... | 1976 | 16659625 |
