The study was design to draw attention to correlation of locals with plants and their conservation status. The research work was carried out in tehsil Takht Bhai, district Mardan during 2008-2010. Fieldwork was conducted using an arrangement of interviews, questioners and personal observation. The IUCN 2001, Red Data List Categories and Criteria was used to determine the conservation status of plants. The present study documents the ethno medicinal and conservation status of 34 plant species belonging to 20 families. Among these 12 species were found to be rare, vulnerable (11 species), endangered (9 species) and Infrequent (2 species). From this study we have concluded that most plant species are going to become endangered and no one plant specie was found dominant because the natural vegetation area was change into urbanization and agricultural reason.

The present work was made to investigate the vegetation structure of shrubs and herbs in research area. Total 48 plant species consisting of 7 shrubs and 41 herbs constructing Cenchrus- Zizyphus-Saccharum community from 9 sites in which 9 communities i.e. Fumaria-Rumex- Xanthium community, Cynodon-Solanum-Sonchus community, Cynodon-Sorghum-Alhagi community, Ajuga- Malvastrum-Calotropis community, Cynodon –Convolvulus-Cyperus community, Ajuga-Saccharum-Chenopodium community, Alhagi-Rumex-Euphorbia community, Saccharum-Cannabis-Xanthium community and Achyranthus-Ajuga-Euphorbia community were found. The contribution of total important values by shrubs was 43.78 and 256.2 by herbs. The soil of the area had better calcium carbonate in the range of (11.72 – 12.99 %), with soil pH (6.45 – 8.11). The EC was found in the range of (0.13-0.22 dS m-1). The concentrations of P and K content were found in the range of (3.54-3.92 mg Kg-1) and (111.21-127.14 mg Kg-1). These results highlight the constant need for long-term ground-based conservation monitoring in combination with satellite-based monitoring of changes in vegetation cover.

Lead (Pb) is a toxic heavy metal that causes physiological and morphological changes in plants. Our current study was aimed at observing Pb-induced changes in seeds of two upland cotton varieties (TM-1 and Z- 747) that were exposed for 24 hours to various Pb concentrations (0, 50, 100, 300, and 500 μM). Seeds of TM-1 showed higher germination percentages, water uptake, and cell viability as compared to Z-747. Changes in nuclei shape, their partial disappearance, and increase in vacuole size were the initial signs of lead toxicity in Z-747, while TM-1 maintained its typical conformations. Cell wall thickening; increase in the number of mitochondria, protein, and lipid bodies; and vacuolation were more prominent in TM-1. In contrast, plasmolytic shrinkage and scattered cell organelles were the key characteristics of Z-747 at higher doses of Pb. Those observations demonstrated that seeds of TM-1 were more tolerant to Pb stress as compared to Z-747 and may be considered a preferred choice for culture on Pb-contaminated soils.

Like other developing countries (Brazil, Argentina, and India) compressed natural gas (CNG) is becoming a popular vehicular fuel in Pakistan. Rapid shifting of diesel and gasoline vehicles to CNG has brought Pakistan the highest number of CNG vehicles in the world. To quantify a possible decrease in vehicular emissions for different types of vehicles, engine and fuel types were monitored for five parameters: SO2, CO, NO, hydrocarbons, and smoke opacity. Emissions from heavy vehicle engines shifting from diesel to CNG showed a decrease in HC (14 times), NO (2.8 times), and smoke opacity (3.2 times), while shifting diesel car engines to CNG resulted in reduced emissions of HC (24.6 times), NO (2.8 times), and smoke opacity (6 times). However, switching of light vehicles such as gasoline car engines to CNG released low emissions of HC (4.6 times), smoke opacity (1.2 times), SO2 (1.2 times), and CO (1.1 times), but an increase in NO (1.2 times) was observed. Similarly, a 4-stroke CNG rickshaw engine increased NO emissions by 1.4 times over a 4-stroke gasoline rickshaw engine.

Challenges concerning fruit trees and grapevines as long lived woody perennial crops require adapted biotechnological approaches, if solutions are to be found within a reasonable time frame. These challenges are represented by the need for correct identification of genetic resources, with the foreseen use either in conservation or in breeding programmes. Molecular markers provide most accurate information and will be the major solution for questions about plant breeders rights. Providing healthy planting material and rapid detection of newly introduced pathogens by reliable methods involving serological and molecular biological tools will be a future challenge of increases importance, given the fact that plant material travels freely in the entire European Union. But also new breeding goals and transgenic solutions are part of the biotechnological benefits, e.g. resistance against biotic and abiotic stress factors, modified growth habits, modified nutritional properties and altered processing and storage qualities. The successful characterization of transgenic grapevines and stone fruit trees carrying genes of viral origin in different vectors constructed under ecological consideration, will be presented. Beyond technical feasibility, efficiency of resistance, environmental safety and Intellectual Property Rights, also public acceptance needs consideration and has been addressed in a specific project. The molecular determination of internal quality parameters of food can also be addressed by the use of biotechnological tools. Patient independent detection tools for apple allergens have been developed and should allow to compare fruits from different production systems, sites, and genotypes for their content of health threatening compounds.

This paper analyzes a phytosociological study and urbanization in Regi Model Township (RMT) in Peshawar, Pakistan. The study was conducted during spring 2015 and a total of 32 plant species were identified belonging to 19 families. The Asteraceae family had the highest number of species 5 spp. while Fabaceae, Polygonaceae, and Brassicaceae had 3 spp. each. Poaceae and Solanaceae had 2 spp. each, while Plantiginaceae, Malvaceae, and Caryophyllaceae had 1 spp. each. In zone 1, a total of 27 plant species were reported in which the Cynodon-Carthamus-Datura community was established on the basis of the importance value index. The soil of this zone was silty clay loamy in texture with a pH of 8.3, nitrogen 0.017%, phosphorus 7.4%, and organic matter (OM) was (0.34 ppm). In zone 2, a total of 23 plant species were reported, and the Xanthium-Parthenium-Cyperus community was established. The soil in this zone was loamy sandy with pH of 8.1, nitrogen 0.020%,phosphorus 3.1%, and OM 0.04. In zone 3 a total of 21 plants species were reported and the Cynodon-Prosopis-Xanthium community was established. The soil in this community was silty clay loamy having a pH of 8.1, nitrogen 0.034%, phosphorus 4.1%, and OM of (0.068 ppm)%. In zone 4, a total of 13 plant species were recorded and the Xanthium-Lepidium-Amaranthus community was established. The soil in this zone was silty clay loamy with a pH of 8.3, nitrogen 0.029%, phosphorus 6.2%, and OM 0.058%, and similarly in zone 5, a total of 11 plant species were recorded in the area where the Cynodon-Parthenium-Cyperus community was established. The soil in this community was loamy sand having a pH of 8.1, nitrogen 0.002%, phosphorus 3.1%, and OM (0.03 ppm). The construction work at RMT was causing the extinction of vegetation and there would be no more wild vegetation in the near future in that particular area.
