synthetic dyes are among the most common contaminants of the environment. therefore, the aim of this study was investigation the removal of basic blue 41 (bb41) and methylene blue (mb) from industrial effluents by useing raw and modified rice stems. in this study raw and modified rice stems treated chemically with citric acid (ca) and were used to explore the potentiality of rice stems for remo...

Periphyton from rice-fish environment of Apatani Plateau, Arunachal Pradesh, India was studied for diversity and productivity (Chlorophylla and biomass) on artificial (glass slide) and natural (rice stem) substrates. Periphyton from rice stems, especially, from cultivars locally known as ‘Amo’ were collected from a depth of 7.0-8.0 cm from surface water and 5.0 cm above from the field bottom. G...

The measurement of carbon isotope discrimination (∆) provides an integrated insight into theresponse of plants to environmental change. To investigate the potential use of ∆ for identifyingshade tolerance in rice, five rice varieties were selected and artificially shaded (53% lightreduction) during the grain-filling period in 2010 and 2011, in Sichuan, China. Shadingtreatment had a significant ...

during the study of rice pests in firoozabad, fars province, iran in june 2002, leafhopper specimens were collected on rice stems. the specimens were identified as typhlocyba (edwardsiana) avellanae (edwards) by unal zeybekuglu, ondokuz mayys university, turkey. this species is a new record for iran.

The contamination of paddy soils by arsenic (As) is a serious problem in rice production areas across the world. This study investigates the effect selenium (Se) has on the formation of iron plaques on the outside of rice roots and the accumulation of As in rice plants. A soil combined sand pot experiment having four concentrations of Se (0, 1, 5 and 10 mg kg -1 ) and two concentrations of As (...

In the world market upland rice (grain) occupies a very modest place, since its production is comparatively limited, and harvests are uncertain since they depend upon precipitation. For this reason upland rice cannot compete with lowland rice. Upland rice is used exclusively in those regions possessing insufficient water for irrigation purposes. CAMUS (2) identifies four types of rice. Of these...

The objectives of this study were to explore the mechanism by which the lodging resistance of the rice population during the late growth period responds to low-temperature, overcast and rainy weather during the reproductive growth stage. Field experiments were conducted using indica rice Yliangyou2 (lodging-resistance variety), IIyou084 (lodging-susceptible variety) and japonica rice Wuyunjing2...

Six closely related N2-fixing bacterial strains were isolated from surface-sterilized roots and stems of four different rice varieties. The strains were identified as Serratia marcescens by 16S rRNA gene analysis. One strain, IRBG500, chosen for further analysis showed acetylene reduction activity (ARA) only when inoculated into media containing low levels of fixed nitrogen (yeast extract). Dia...
