| wild rice: the indian's staple and the white man's delicacy. | wild rice (zizania aquatica) is an annual aquatic grass which grows in shallow lakes, marshes and in sluggish streams in various parts of the world. the grain of wild rice has been harvested by the indians of the united states and canada for many centuries. explorers entering the territories of the northern lake states of america a few centuries ago described wild rice as a spontaneous crop which does not require plowing or sowing providing an abundant harvest of palatable and nourishing grain. ... | 1981 | 7030624 |
| development of male flowers in zizania aquatica (north american wild-rice; gramineae). | we investigated the histology and developmental morphology of flowers of wild-rice (zizania aquatica), a member of grass subfamily oryzoideae, to determine whether male flowers in this species develop in a manner similar to those in the subfamily panicoideae, a group that includes many species with unisexual flowers. zizania has evolved unisexual flowers from hermaphrodite ancestors and is only distantly related to the panicoideae; the origins of unisexual flowers are independent in the two taxa ... | 2000 | 10817969 |
| some effects of acidic growing conditions on three emergent macrophytes: zizania aquatica, leersia oryzoides and peltandra virginica. | transplants of zizania aquatica l., leersia oryzoides (l.) shwartz, and peltandra virginica (l.) schott and endl. were grown for ten weeks in simulated marsh conditions under acidic (ph 3.0, ph 4.0) treatment regimes and compared with controls (ph 5.6). mortality was low in all treatments and nearly all plants of z. aquatica and l. oryzoides flowered. under acidic conditions, transplant height and root biomass of z. aquatica were significantly reduced, with greater culm numbers and total lengths ... | 1992 | 15091985 |
| responses of butachlor degradation and microbial properties in a riparian soil to the cultivation of three different plants. | a pot experiment was conducted to investigate the biodegradation dynamics and related microbial ecophysiological responses to butachlor addition in a riparian soil planted with different plants such as phragmites australis, zizania aquatica, and acorus calamus. the results showed that there were significant differences in microbial degradation dynamics of butachlor in the rhizosphere soils among the three riparian plants. a. calamus displays a significantly higher degradation efficiency of butac ... | 2011 | 22432278 |
| quantitative profiling of feruloylated arabinoxylan side-chains from graminaceous cell walls. | graminaceous arabinoxylans are distinguished by decoration with feruloylated monosaccharidic and oligosaccharidic side-chains. although it is hypothesized that structural complexity and abundance of these feruloylated arabinoxylan side-chains may contribute, among other factors, to resistance of plant cell walls to enzymatic degradation, quantitative profiling approaches for these structural units in plant cell wall materials have not been described yet. here we report the development and applic ... | 2015 | 26834763 |
| contribution of individual phenolics to antioxidant activity and in vitro digestibility of wild rices (zizania aquatica l.). | zizania aquatica l. was analysed for total flavonoids, phenolics and hplc profile in both free and bound phenolic fractions. the highest content of flavonoids (378-455mgre/kg) was detected in bound fractions, while the highest polyphenols content (1061-2988mggae/kg) was determined in free fractions. additionally, predominant phenolics were identified. to understand the contribution of individual phenolics to an antioxidant activity their mutual correlations were evaluated. regarding free flavono ... | 0 | 27719885 |
| the evaluation on the cadmium net concentration for soil ecosystems. | yixing, known as the "city of ceramics", is facing a new dilemma: a raw material crisis. cadmium (cd) exists in extremely high concentrations in soil due to the considerable input of industrial wastewater into the soil ecosystem. the in situ technique of diffusive gradients in thin film (dgt), the ex situ static equilibrium approach (hac, edta and cacl2), and the dissolved concentration in soil solution, as well as microwave digestion, were applied to predict the cd bioavailability of soil, aimi ... | 2017 | 28287500 |
| [effects of saltwater incursion on the microbiological characteristics and denitrification in a riparian rhizosphere soil in chongming island of shanghai, east china]. | a simulation test was conducted to study the effects of saltwater incursion on the microbiological characteristics and denitrification in the riparian rhizosphere soils vegetated with different plants in chongming island of shanghai. saltwater incursion changed the microflora in the rhizospheric soils. except for actinomycete whose quantity had slight increase, the quantities of bacteria, fungi, nitrifiers, and denitrifiers all decreased to some extent by saltwater incursion, with the denitrifie ... | 2012 | 22803478 |
| influence of rhizosphere microbial ecophysiological parameters from different plant species on butachlor degradation in a riparian soil. | biogeochemical processes in riparian zones regulate contaminant movement to receiving waters and often mitigate the impact of upland sources of contaminants on water quality. however, little research has been reported on the microbial process and degradation potential of herbicide in a riparian soil. field sampling and incubation experiments were conducted to investigate differences in microbial parameters and butachlor degradation in the riparian soil from four plant communities in chongming is ... | 2012 | 22565253 |
