Salinity increase ethylene level in root rhizosphere. Plant growth promoting rhizobacteria having ACC deaminase have ability to mitigate the adverse effect of enhanced level of ethylene. Two field experiments were carried out at two different sites during 2013. The site1 had ECe 9.42 dS m-1 and SAR 20.75 (mmolc L-1)1/2, while site2 had ECe 7.51 dS m-1 and SAR 16.25 (mmolc L-1)1/2. Four PGPR strains (KS 44, KS 7, KS 41, KS 42) having ACC deaminase activity were selected for this study. Randomized completes block design (RCBD) was used and hybrid sunflower seeds (SMH-0917) were inoculated with these PGPR strains. The crop was harvested at maturity and data were recorded about plant height, shoot dry weight, head dry weight, number of seed head-1, 1000 seed weight, seed weight head-1 and seed yield kg ha-1. The data were statistically analyzed by using soft ware statistic 8.1. The average increase in grain yield (site 1 + site 2) was 110.07, 108.89, 49.09, 65.77 and 69.70% over control due to inoculation with KS 44, KS 7, KS 41, KS 42 and KS mix treatments respectively. On the basis of statistical analysis, the bacterial strains KS 44 and KS 7, were declared as most promising strains on both sites. Hence these two strains (KS 44 and KS 7) could be used to mitigate negative impact of salinity stress on sunflower. © 2016, Pakistan Botanical Society. All rights reserved.

After water the tea is the biggest beverage use worldwide. This study is aimed to find out the knowledge, attitude and practices of local population of Union Council Koaz Bahram Dehri District Charsada, Khyber Pakhtunkhwa Pakistan towards green tea. A descriptive observational study was design. Data were collected from 150 subjects through a self design questionnaire. The majority of participants were males belonging to different age groups. The ratio of education was reported low. The local populations have sufficient knowledge about green and also used it for different purposes.

Phytoremediation potential of L. minor for cadmium (Cd), copper (Cu), lead (Pb), and nickel (Ni) from two different types of effluent in raw form was evaluated in a glass house experiment using hydroponic studies for a period of 31 days. Heavy metals concentration in water and plant sample was analyzed at 3, 10, 17, 24, and 31 day. Removal efficiency, metal uptake and bio-concentration factor were also calculated. Effluents were initially analyzed for physical, chemical and microbiological parameters and results indicated that municipal effluent (ME) was highly contaminated in terms of nutrient and organic load than sewage mixed industrial effluent (SMIE). Results confirmed the accumulation of heavy metals within plant and subsequent decrease in the effluents. Removal efficiency was greater than 80% for all metals and maximum removal was observed for nickel (99%) from SMIE. Accumulation and uptake of lead in dry biomass was significantly higher than other metals. Bio-concentration factors were less than 1000 and maximum BCFs were found for copper (558) and lead (523.1) indicated that plant is a moderate accumulator of both metals. Overall, L. minor showed better performance from SMIE and was more effective in extracting lead than other metals. © 2016 Taylor & Francis Group, LLC.
