The present research work aimed to explore the ideal date of pruning which produce plants with excellent growth and flowering characteristics of Rosa centifolia during winter months where most scented flowers are disappear and marketing is lucrative. Pruning experiment was carried out on most important rose flower specie Rosa centifolia at Faisalabad during 2010-2012. The experiment was laid out in Randomized Complete Block Design (RCBD) with five different pruning dates during winter months i.e. second week of December, end of December, second week of January, end of January and second week of February. Plants that were pruned during the end of December dominate all growth parameters (plant height, number and length of branches, days to first bud emergence and number of buds plant -1 ) and flowering characteristics (number, diameter and weight of flowers) that were studied in this experiment. Overall plant growth was also the best in plants when pruned at the end of December. It seems all

A total census of the tree population on selected roads was carried out and then studied for various parameters. Shannon–Wiener index, Reciprocal of Simpson’s diversity index, and Shannon Evenness were among the different species diversity indices which were studied. Observational results showed that the selected roads in the city hold low tree diversity, with nearly 2858 trees of 34 species, 30 genera, and 15 families. Mainly exotic tree species dominated the plantation of selected roadsides. The topmost three species contributing approximately 60% of the tree population are Conocarpus erectus, Eucalyptus crebra, and Terminalia mantaly. Despite the dominance of exotic tree species, many native tree species are also growing along selected roadsides. Since, Faisalabad has been reported as one of the most polluted cities in the world due ...

Vegetation was sampled by quadrat method, which were laid along a transect line at different selected sites. All ecological parameters like species composition, pair-wise association and distributional pattern, and community structure significantly changed with altitudinal gradient. Species with broad distributional range can be related to high degree of tolerance to a variety of environmental stresses. Species growing at low altitudes were different in their structure and contribution towards community structure. High altitude species are generally with restricted distributional range. Species richness was the maximum at moderate elevation because of better growth conditions. Chrysopogon serrulatus Trin., Cymbopogon jwarancusa (Jones) Schult. and Cynodon dactylon (L.) Pers. dominated the Potohar region, all ...

Fifteen different habitats in Neelum valley (Kashmir), using quadrat method along altitudinal gradient were studied for the plant ecological attributes including; soil plant interaction, species composition and vegetation cover to test the hypothesis that soil factors are the major determinants of species distribution. Redundancy analysis (RDA) showed a clear impact of soil characteristics on vegetation. Rostraria pumila, Pennisetum orientale, Sorghum nitidum and Arundinella sp. had a strong association with the Kail (KL) site influenced by soil Ec. Distribution of Lolium temulentum, Poa nemoralis, and Saccharum spontaneum, at Chilhana (CH) site seemed to be affected by the moisture content only. Species distribution at Nagdar (NG), Kundal shahi (KS), Kairan (KR) and Dawarian (DW) site was affected by Ca and PO4 conte...

The data for density, frequency, cover and other derived parameters was collected using fixed quadrate method and analyzed by using canonical correspondence analysis technique. It was concluded that 80% disturbance was caused by stone crushing, 10% disturbance by grazing and 5% disturbance by harvesting and remaining by fire with other factors. Environmental factors significantly affect the growth as well as distributional pattern of the native plant species. Anthropogenic activities, especially stone crushing significantly affect community structure and composition, and distributional pattern as more stress tolerant species replace the sensitive ones. © 2016 Friends Science Publishers

Solms is a floating hydrophyte that dominates metal-polluted wetlands such as industrial effluents. Keeping in view its capability to hyper-accumulate metal ions, the effect of cadmium stress on structural and functional features of photosynthesis was investigated to assess growth response under metal toxicity. Plants were randomly collected from polluted areas of Sheikhupura-Lahore road and multiplied for about one year at research sites of old Botanic Garden, University of Agriculture, Faisalabad. Plants were thereafter treated with cadmium stress and levels of cadmium were 0 (control), 50, 100 and 150 mg L in aqueous solution. E. crassipes reduced their biomass, and photosynthetic features like chlorophyll pigments, net CO2 assimilation rate, sub-stomatal CO2 concentration and stomatal conductance under cadmium toxicity. Water use efficiency also decreases significantly in response to metal stress, but this species is a floating hydrophyte. Water is f...

Two busy roads varying in age and traffic volume were selected i.e., Faisalabad-Sargodha road (FSR) and Pindi Bhattian to Lillah (M-2) in the Punjab, Pakistan. Results showed raised levels of Pb in both plants and soil samples along both roads. The range of Pb concentration in plants was 0.08-3.98 and 1.95-4.74 mg kg- 1 for soil. Higher Pb contamination was recorded along FSR road as compared to M-2. Among seasons, the higher Pb concentration was found during summer, probably due to very high temperature. Among all the plants studied, Calotropis procera accumulated the highest level (3.98 mg kg- 1 dry wt.) of Pb; Thus, it can be used as good biomonitor/phytoremediator at Pb contaminated areas.

The purpose was to document the indigenous knowledge of the native people used in the preparation of herbal medicines. To get the data on traditional uses of medicinal plants, 20 informants were interviewed. Quantitative ethnobotanical indices, i.e., use value (UV), relative frequencies of citation (RFC), informant consensus factor (Fic), fidelity level (FL), data matrix ranking (DMR), preference ranking (PR), and jaccard index (JI), were calculated for the recorded medicinal plants. A total of 50 medicinal plants belonging to 33 families used in 13 disease categories were documented. Leaves were the frequently used plant parts, and decoction was the commonly used method for herbal medicine. Plants with high use value were Berberis lycium (2.05), Impatiens glandulifera (1.95), Artemisia scoparia (1.75), Ageratum conozoides (1.75), and Achillea millefoli...

To get quality flowers, nutrient optimization is required and there is a need of estimation of its growth pattern, consumption of nutrients and relative effectiveness of different nutrient levels on its health and vigor. The present study was performed to optimize doses of micro and macro nutrients on growth and flowering of dahlia. The results indicated that micronutrient concentration of 7.5 mlL and macronutrient concentration of 6 ml L proved best-1-1 with the maximum values for plant height, number of leaves, number of side shoots, leaf area, number of tubers per plant, flower diameter and least days to flower emergence of dahlia. The other treatments although exhibited better response than control treatment but their effect on growth were lesser than T. 15

Two Urochloa species, U. deflexa and U. ramosa, were distinguished from the rest of the species by absence of median vascular bundles. Presence of sclerenchyma strands on the abaxial side only makes the genus Cenchrus distinct from the remaining species within the tribe. The distribution pattern of bulliform cells proved to be helpful in the differentiation among Cenchrus species. Large macrohairs with deep penetration on the adaxial surface are characteristic of Digitaria nodosa. The observed diversity in anatomical markers could be used to clarify the status of problematic taxa in tribe Paniceae. Saddle shaped silica bodies, microhairs and bulliform cells deeply penetrating the mesophyll are the prominent characters of this tribe, which justify placing all these species in the same tribe. Anatomical markers of taxonomic importance a...
