A field experiment was performed to investigate the growth performance and the growth stage-dependent changes in activities of antioxidative enzymes and concentration of malondialdehyde (MDA) in leaves of rice subjected to treatment with (NF-M) or without straw mulching (NF-WM) under non-flooded conditions compared with continuously flooded treatment (CF). Compared with the NF-WM treatment, mulch application significantly increased the flag leaf area per plant before heading, tillers number and plant height at the early period of tillering stage. There was no significant difference between the yield of the NF-WM and CF treatment. However, the yield...

In order to evaluate the accumulation capacity of heavy metals in mosses, the total contents of eight elements (Cu, Zn, Fe, Mn, Ni, Pb, Cd, Cr) determined by Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) and Atomic Absorption Spectrophotometry (AAS) methods were compared in four types of indigenous mosses (Brachythecium plumosum, Eurhynchium laxirete, Taxiphyllum taxirameum, Haplocladium strictulum), which were collected from different sampling sites in the Chengdu city, China. The study found that heavy metal concentrations showed significant differences in interspecies and intraspecies comparison, while the accumulation...

A field research was carried out in the years of 2005, 2006 and 2007 in order to determine the effect of irrigation and water stress imposed at different growth stages on quantity and quality traits of Virginia tobacco plants. A randomized complete block design with four treatments and three replications was applied at the Rasht tobacco research station. Treatments were: no irrigation (dryland farming) as the complete water stress (WS0), water stress till the end of flower bud forming stage (WS1), water stress till the end of flowering stage (WS2) and full irrigation (WS3) as control in each cropping season....

An experiment was conducted to study the effect of heavy metals (Cd, Cr and Pb), soil texture (sandy, loam and clay) and incubation periods (7, 15, 30, 60, 90 and 120 days) on soil respiration (CO2 evolution) during sugarcane trash decomposition in laboratory conditions of the Indian Institute of Sugarcane Research, Lucknow, India. Surface soils (0-15 cm) were collected from agricultural fields and crop residue of sugarcane trash (Saccharum officinarum L.) was taken in the institute farm. Crop residue (10 t/ha) and heavy metals (10, 50, 100, 1000 μg/g) were mixed and incubated at 30°C ± 2°C in an incubator. The rate of soil...
Identification of Triticum aestivum L., Triticum spelta L. and Triticum durum DESF. genotypes on the HMW-GS base

The main goal of this work was to identify genotypes of three wheat species Triticum aestivum L., Triticum spelta L., Triticum durum DESF.) on the basis of individual high-molecular-weight glutenin subunits (HMW-GS) and to predict their technological quality. Detection of HMW-GS was carried out by the standard reference method ISTA SDS-PAGE and the Glu-score was calculated according to the catalogue of alleles for HMW-GS. Among the common wheat varieties the highest Glu-score (10) was determined for the cultivars Axis, Istra and Solara. The most frequently occurring HMW-GS in genotypes of Triticum aestivum L. were 0; 7 + 9;...
Soil degradation: a problem threatening the sustainable development of agriculture in Northeast China

Soil degradation that results from erosion, losses of organic matter and nutrients, or soil compaction are of great concern in every agricultural region of the world. The control of soil erosion and loss of organic matter has been proposed as critical to agricultural and environmental sustainability of Northeast China. This region is bread basket of China where the fertile and productive soils, Mollisols (also called Black soils), are primarily distributed. In this paper, we introduce the importance of Northeast China's grain production to China, and describe the changes of sown acreage and grain production in past decades. This paper also summarizes...
