  The study was confined to the 3 medicinally important species of the genus Artemisia Linn. The morphological features, such as, plant size, leaf-shape and size, petiole length, the inflorescence type and the details of capitulum, i.e., the disc and ray florets were studied from the herbarium specimens preserved in the Quaid-I-Azam University Herbarium. Many properties and the uses of these species were determined. The studies on morphological characters revealed that the characters like, heads either homogamous or heterogamous and the receptacle either glabrous or hairy, number of the florets per head were taxonomically most important to differentiate these species. Among these species it was observed that A. absinthium Linn. was mostly used against liver diseases.

  Ethnopharmacological survey was conducted in Galliyat areas of Tehsil Abbotabad (NWFP) Pakistan. Being apart from city the local people preferably use medicinal plants for their common ailments by traditional methods. Galliyat is dressed up with a wide range of medicinal flora. Indigenous plants are interactly associated to the culture and traditions of local peoples. So ethnopharmacological survey yielded interesting results. The survey comprised plant-collection trips, interviews and meetings with local people and rural herbalists. In a total of 41 wild plant species, belonging to 40 genera of 33 families were used by local inhabitants, for medicinal purposes.

  The present study is confined to the palynological studies (pollen morphology and pollen fertility) estimation of some cultivated plant species of University of Arid Agriculture Rawalpindi campus. Pollen morphology of the selected species indicate that the pollen of these species varies in shape i.e, spherical, elliptical and oblong. The pollen fertility ranged from 60-100% among these species. In Bougainvellia glabra, Brassica campestris, Consolida ambigua, Tecoma stans, Crysanthemum indicum, Tagetis patela, Tradescantia indica, Hibiscus rosa-sinensis the range of pollen fertility is 98-100% whereas Catharanthus roseus, Canna indica, Calendula officinalis, Hibiscus circus, Jatropha integrrima, Jasminum grandiflora, Rosa indica and Rosa alba the range of fertility is below 98%. Pollen fertility studies have been modified helpful for the recognition of wide range of variation existing within plant species and differentiating plant species with genera.

  The present study was carried out to assess, record and report the ethnobotanical potential of the Kala Chitta Hills (salt range) of District Attock. Results of the present investigation were based on medicinally important 40 species (21 families). These plant species has other benefits too along with their major utilities like apiculture, sericulture, food and fruits. The Kala Chitta Hills of the Salt Range are very unique. Due to increase in population masses, demands of people increases, causing great pressure on the products of the area. This continuous pressure for last few decades has disastrously damaged the natural characteristic ecosystem of the area. The region is very rich in having medicinal plants. To understand the indigenous knowledge of the local people through ethnomedicinal study is very important for creating awareness among them regarding sustainable natural resource management. About 100 informants including local people, hakims and medicinal businessmen were interviewed for collection of ethnomedicinal data through the questionnaire. Results were compiled, issues were discussed, conclusion was made and recommendations are suggested for the future.

  Ten isolates of Enterococcus faecalis were tested for antimicrobial activity against closely related and less closely related pathogenic gram-positive and gram-negative indicator strains. Using the agar spot test Enterococcus faecalis MI2, MI6, MI126 and MI128 showed strong activity against selected enterococcal isolates. E. faecalis MI6 and MI128 showed strong antimicrobial activity against Listeria innocua NCTC. 11288 but enterococcal isolates did not show activity against selected pathogenic strains of some other species. A clear inhibition zone around the spotted test culture observed antimicrobial activity of E. faecalis isolates. The diameters of zones of inhibition ranged from 2-8 mm.

  The effect of NaCl on heat tolerance of Enterococcus faecium BAR1 and Enterococcus faecalis MI2 was determined at 55, 60 and 62.5oC for half an hour. Cells of both isolates were grown in Brain Heart Infusion broth containing 6.5% NaCl. Exponential phase cells were used as inoculants. Cells of both isolates were found resistant to heat treatment as compared with cells grown in BHI broth without presence of salt. The decimal reduction times (D-values) were determined by 1 log fall in viable count. Both isolates showed similar results at 55oC but at 60oC E. faecalis MI2 showed higher D-value than E. faecium BAR1. At 62.5oC E. Faecium BAR1 was found more tolerant to heat treatment than E. faecalis MI2. Experiments showed that the presence of salt in the growth medium induces more heat tolerance in enterococci than the cells grown in normal medium.

  Effect of pH of the growth medium on heat tolerance was investigated in Enterococcus faecium BAR1 and Enterococcus faecalis MI2. The heat tolerance was determined at 55, 60 and 62.5oC for half an hour. Cells of both isolates were grown to exponential phase at pH 5 or 7.4. Cells grown at 37oC at pH 5.0 were found tolerant to heat treatment as compared with cells grown at pH 7.4. Cells did not differ in their tolerance to heat at 55oC but at 60 and 62.5oC, cells of E. faecium BAR1 were found more heat tolerant than the cells of sE. faecalis MI2. The acidic pH of the growth medium had affected the susceptibility of E. faecium BAR1 and E. faecalis MI2 on heat tolerance. The cells grown at acidic pH showed greater heat tolerance that the cells grown at neutral pH.

  The heat resistance of exponential phase cells of environmental barley isolates Enterococcus faecium BAR 1 and a hospital isolate Enterococcus faecalis MI 2 grown at 37 or 45 was determined at 55, 60 and 62.5 ° C for 30 min. From the survival curves, the decimal reduction times (D-values) were determined. Cells grown at 45° C showed higher D-values. It was determined that the exponential phase cells grown at 45 were more resistant to heat than the heat resistance of cells grown at 37° C. The cells of both isolates were found resistant to heat treatment at 55, 60 and 62.5 as compared with the control in which cells were grown at 37° C and treated at 62.5° C.

  The present study was conducted to document the traditional use of medicinal plants as indigenous recipes for the treatment of human and domestic animals. As the people of the area are poor and living far away from the city, so they rely mainly on medicinal plants for various diseases. Flora of the area constitutes a large number of medicinal plants including trees, herbs and shrubs. The present study comprised on data collection from local reliable people of the area by interviewing them in exploring valuable medicinal plants and traditional knowledge about them. In a total of 28 wild plant species belonging to 26 genera and 24 families were used traditionally for medicinal purposes.

  Seed of 10 sesame (Sesamum indicum L.) cultivar supplied by National Agriculture Research Center, Islamabad were tested for seed borne mycoflora by standard blotter paper test. 11 phytopathogenic fungi viz., Alternaria brassicola, A. redicina, Aspergillus alba, A. flavus, A. niger, A. viridus, Cephalosporium sp., Curvularia sp., Drechslera sp., Fusarium sp. and Penicilliu, sp. were found associated with these samples. Percentage of seed sample infection and extent of fungal infection ranged from 0.75-53%. The effect of associated fungi on germination capacity was evaluated by the standard rolled paper towel method. The associated fungi decreased the germination potential. 11 fungi were isolated from abnormal seedling and ungerminated seeds.
