1Seasonal Inhomogeneity of Soot Particles over the Central Indo-Gangetic Plains,India:Influence of Meteorology显示文摘Black carbon(BC) particles play a unique and important role in earth's climate system.BC was measured(in-situ) in the central part of the Indo-Gangetic Plains(IGP) at Varanasi,which is a highly populated and polluted region due to its topography and extensive emission sources.The annual mean BC mass concentration was 8.92 ± 7.0 μg m^(-3),with 34%of samples exceeding the average value.Seasonally,BC was highest during the post-monsoon and winter periods(approximately 18 μg m^(-3)) and lower in the premonsoon/monsoon seasons(approximately 6 μg m^(-3)).The highest frequency(approximately 46%) observed for BC mass was in the interval from 5 to 10 μg m^(-3).However,during the post-monsoon season,the most common values(approximately 23%) were between 20 and 25 μg m^(-3).The nighttime concentrations of BC were approximately twice as much as the daytime values because of lower boundary layer heights at nighttime.The Angstrom exponent was significantly positively correlated(0.55) with ground-level BC concentrations,indicating the impact of BC on the columnar aerosol properties.The estimated mean absorption Angstrom exponent was 1.02 ± 0.08 μg m^(-3),indicating that the major source of BC was from fossil fuel combustion.Significant negative correlations between BC mass and meteorological parameters indicate a pronounced effect of atmospheric dynamics on the BC mass in this region.The highest mean BC mass concentration(18.1 ± 6.9 μg m^(-3)) as a function of wind speed was under calm wind conditions(38%of the time).SINGH B.P.

10Vegetative propagation of Dalbergia sissoo:effect of growth regulators,length,position of shoot and type of cuttings on rooting potential in stem cuttings显示文摘The effect of auxins (IAA or IBA at 100,200,500 mg L 1) on rooting and sprouting parameters differed significantly (p < 0.05).Rooting and sprouting percentages were higher in some treatments while other parameters were significantly higher in other treatments.The results of the present study revealed that rooting was significantly (p < 0.05) affected by the length of cuttings,as well as the position of shoots and type of cuttings.On average,86.0 per cent rooting was observed in the 30-cm long cuttings compared to the other two lengths of cuttings,i.e.,20 and 25 cm,irrespective of any auxin treatment.In a control set,without any auxin treatment,a maximum of 60.0% rooting was recorded in the 30-cm long cuttings and a minimum of 40.0% of the cuttings rooted in the 20-cm long cuttings.Similarly,cuttings collected from the lower and upper portions of shoots resulted in 72.5 and 52.5 per cent rooting respectively,irrespective of auxin treatments.Maximum rooting was observed in the lower portion (40.0%) of cutting compared to the upper portion (30.0%) in the control set without auxin treatment.Leafless branches produced maximum (72.0%) rooting compared to the leafy cuttings (35.0%),irrespective of the auxin treatment.The leafy cuttings produces a minimum of 15.0% sprouting and rooting in the control set.Bhupendra SINGH Rajendra YADAV B.P.
