The experiment was laid out in a factorial split plot design on grassland in peaty gley soil. Mounding increased soil bulk density, while drainage reduced carbon concentration in 0−10 cm layer. Soil organic carbon concentration in the 0−10 cm layer was increased by fertilisation. Mounding did not have any effect in soil organic carbon. The concentration of nitrogen in the in 0−10 cm was significantly reduced by drainage and was not affected by mounding or fertilisation. Soil microbial biomass carbon was not affected by drainage, mounding or fertilisation. Ammonium (NH4+) was significantly increased by mounding and fertilisation, while none of the treatment affected nitrate (NO3−) availability.

In the present research, we report the results of experiments aimed at optimizing acclimatization of tea clone Iran 100 plantlets (Camellia sinensis (L.) O. Kuntze) by using different types and ratios of potting media. Potting media like peat moss, vermiculite and perlite having various ratios are mixed together. This experiment was done in four repetitions by keeping the base of randomized complete block design. The properties such as survival rate, number of leaves, plant height and root length were measured and recorded in the period of the experiment. The collected data was analyzed by SAS statistical software and the mean of data was evaluated by the Tuckey Test using the probability of 1 percent. Nevertheless, the mixture containing peatmoss+ vermiculite+ perlite (2:1:1; v/v/v) resulted in increased percentage of plant survival, root length plant height and number of leaves of tea clone Iran 100 and it is therefore, a recommended medium for growth of the cultivar during acclimatization.

Also it a key element in response to stresses. In the present study, we investigated role salt stress in induced programmed cell death or apoptosis wheat (Triticum aestivum L.) suspension cell culture. Wheat suspension cells were exposed to 500 Mm NaCl and cell death was determined using several apoptosis assay. We observed morphological and biochemical apoptosis features such as nuclear condensation, DNA laddering, transferase mediated dUTP nick end labeling. Positive TUNEL and reduction cell viability results were obtained treatment wheat suspension cell. The results indicate that 500 mM NaCl can induced pcd in suspension cell.

Soil samples from two plots within Dabagi research farm of Usmanu Danfodiyo University Sokoto were used. These samples were taken from Dabagi Upland 2 (DUP2) and Dabagi Lowland (DLL) at the depth of 0-30cm. The seeds were sown in the soil samples of 0.0dSm-1, 2.2dSm-1and 2.8dSm-1 salt levels and observed until complete germination, and growth parameters (height and collar diameter) were measured fortnightly for 12 weeks. It was observed that salinity influenced the germination of seeds of the species with A. senegal (54%) showing a better germination at 2.2dSm-1 compared with P. biglobosa (44%). Secondly, the tree seedlings showed significant differences in their growth over the period of the study. It was observed that on the whole when compared, P. biglobosa showed a significant difference at (P<0.05) between 0.0dSm-1 and 2.8dSm-1. The result indicated that P. biglobosa though a savanna species, does not thrive well in high saline soils and should not be used in agro-forestry plot deep in the savanna where irrigation water may tend to increase soil salinity.

Passing the roads through low to moderate slopes and areas with high level of stability, reduces the costs of excavation, earth filling, land stabilization, excavation gable roofs and earth filling, and thus reduces construction costs. This research was carried out in the Shafaroud forest in the west of Guilan province. The paper aims to develop a method using the GIS technology and MPSIAC model to produce the stability map for designing the new roads network in the study area. The results showed that the proposed road network with a length of 23908 meters compare to existing roads network with a length of 25280 meters, could generate a suitable coverage among the parcels. The length of the proposed roads network is 1372 meters less than the length of the existing roads and creates the highest percentage of coverage with the least length so that in addition to the reduction of costs the forestry plans could be directed in the way of sustainable development. Some 12% of the proposed road passes through regions with high stability more than the existing road and the passage of the proposed road through the unstable regions as compared to the existing road has reduced two times and has had a significant difference in the level of 99% and totally has reduced the corrosive effects of the road on the nature. Ultimately, the results yielded show that using the GIS can increase the accuracy of the designing and quality of the forest road network and reduce the costs.

For this reason, major elements (Si, Al, Fe, Mn, Mg, Ca, Na, K, Ti, and Zr) as metal oxides and mineralogy composition of bulk soil and rocks were analyzed. Total content of some trace elements (Cr, Ni, Cu, Zn, Cd, Sn, and Pb) were measured in bulk soil samples as well. The studied area is part of arid region in southern Iran with predominant sedimentary rocks and evaporite formations. Coefficients between the elements of each subgroup are positive and significant (p<0.05), indicating that their presence can be accounted for by similar reasons. In general, soils developed on metamorphic and igeneous parent rocks rather than evaporates indicated distinct accumulation of Si, Al, Fe, Mn, K, Ti, and Zr in different particles. Indices based on soil macro elements, such as CIA, CIW, PWI, WIP could express the variations in unweathered materials and rate of weathering and can be taken as an index of soil development. In addition to high contents of alkali and alkali earth elements of the sand and silt rich soils, both the Chemical Index of Alteration values (4.61 to 67.40), Chemical Index of Weathering values (4.82 to 71.73) and also high Product of Weathering Index (PWI) and Weathering Index of Parker (WIP) contents, suggests a relatively mild weathering source area.

Application of wastewater on the soil properties showed that, irrigation with wastewater decreased soil pH and CCE, and on the other hand, increased Ec, SAR and OM, compared with non irrigated soils. The change of Zn and Cu fractions with depth for non-irrigated soil showed that Zn and Cu are strongly associated with the residual fraction. Chemical forms of Cu and Zn tendency to decrease with depth. Increased wastewater after 6 and 12 months caused increases in all chemical forms of Zn (except Carbonate form), especially in the surface layer. The mobility factor of Zn was reduced in three layers after 6 months of irrigation. In contrast, after 12 months of irrigating with wastewater resulted in the transformation of metals from the non mobile fraction towards the mobile fraction and finally mobility factor of Zn was increased in three layers. The result showed higher concentrations of chemical forms of Cu in the surface layers than sub surfaces. In irrigated soil, concentration of Chemical forms of Cu tendency to decrease with depth. The mobility factor of Cu was increased in three layers after 6 and 12 months of irrigation. Generally, application of wastewater caused increase in chemical forms of Zn and Cu and finally mobility factor, however, these factors were below of very mobile range.
