Pterocarpus species are well known for their nutritional and medicinal values, in order to examine the similarities or differences in the chemical profile of some common Pterocarpus species, four species of the genus namely; Pterocarpus erinaceus, P. mildbraedii, P. osun and P. santalinoides were analyzed using HPLC combined with Principal component analysis (PCA) and Hierarchical clustering analysis (HCA). This study aims to investigate the chemical fingerprints of the species and compare them in order to highlight the similarities in their chemical constituents. The ethanol extract of each sample was taken and filtered through a 0.45 μm millipore membrane filter and then transferred into the HPLC vial before injecting it into the HPLC machine. PCA and HCA were performed on the relative retention times and percentage peak composition. The species were chemically similar with nine (9) peaks in common, the most prominent peaks in all samples appeared at 3.26 min which corresponds to gallic acid (a known compound). Cluster analysis revealed some similar chemical variables with Gallic acid being the major compound in the Pterocarpus species and could be used as a marker compound for taxonomic purposes.

A comparative study of leaf epidermal features of selected species of the family Sapindaceae in Nigeria was undertaken with a view to obtain additional characters for the elucidation of taxonomic relationships, delimiting species and identification of the taxa. The epidermises were separated from the mesophyll by soaking in concentrated Nitric acid. Bubble appearance on the surfaces of the leaves indicated their readiness for separation. They were then rinsed in water thrice before the layers were separated with the aid of forceps and Camel hair brush, stained with Safranin O. It was then mounted in 25% glycerol on clean glass slides, covered with cover slips. The micro morphological characters of leaf were more or less uniform in all taxa in the family. The adaxial cuticle was striated in most species. The polygonal epidermal cells with straight anticlinal walls on the adaxial surface of Cardiosermum halicacabum separated it from the other species with irregular shaped epidermal cells. Undulated anticlinal walls were observed on both surfaces. The leaves were hypostomatic in most species except in C. halicacabum where amphistomaty was observed. Stomata types included anomocytic, tetracytic and staurocytic but the anomocytic stomata were the most predominant.

Forty-five rosemary genotypes collected from different parts of Ethiopia were evaluated for quantitative morphological traits to estimate the genetic variability, heritability and association of characters. The genotypes displayed significant differences for all of the studied traits, showing the presence of wide variability among the tested genotypes. The genotypic and phenotypic coefficients of variation were found to be medium and high for all growth and yield traits except for leaf length. Moderately high to high broad-sense heritability (0.66 -0.97) coupled with moderate to high genetic advance as a percent of the mean (10.37 -79.14) values were found for all traits. Correlation coefficient and path coefficient analysis revealed that characters vis. branch number plant-1, fresh leaf weight plant-1, dry leaf weight plant-1, fresh leaf yield ha-1, and essential oil content had a high positive direct effect and significant positive association with essential oil yield ha-1. Thus direct selection for these traits would be quite effective for essential oil yield enhancement in rosemary. In general, the studied accessions were diverse in nature and could be exploited in the conservation, breeding and commercialization of the crop.

A study was conducted in southern Mali to characterized Parkia biglobosa populations in the aim to contribute to the domestication of the species. Fields and fallows in the north sudanian, south sudanian and north guinean zones were concerned. Adult trees were marked in plots of 0.25 ha each and leaves and fruits were harvested from each tree for characterization. Petiole and laminar length, number of pairs of pinnae and leaflets, pedicel and pod length, pod wide, pod and seed weight, number of seed per pod were measured. The north guinean zone showed the highest number of pairs of pinnae and leaflets, the longest pods (23.06±9.91 cm in the fields), the highest mean seed weight (3.74±0.96 g in the fields) and the highest mean number of seeds per pod (17 ± 3 seeds in the fields). The South Sudanian zone showed the longest pedicels (3.85±1.08 cm in the fallows), the highest mean laminar length (18.02 cm) and mean petiole length (6.45 cm) in the fields but the same mean number of seeds per pod as for the north Guinean. The north Sudanian zone showed the widest (17.88±7.98 cm in the fields and 18.24±2.11 cm in the fallows) and heaviest (14.87±3.95 g in the fallows) pods. Leaf variables like the number of pairs of pinnae and leaflets seem to be influenced by the climatic gradient. The others leaf, pod and seed variables seem not to be influenced by the climatic gradient. These findings suggest that many leaf and fruit variables are controlled by endogenous factor that could be genetic. However, the manifestation of the endogenous factor seems to be influenced by factors such as environment and management practices.

A comparative wood anatomical study of six species of the genus Acacia commonly found in Nigeria was carried out. Wood samples were collected from matured branches of plants in different locations in Mazah and Shere Hills, Jos, Plateau State, Nigeria. Transverse, tangential and radial longitudinal sections as well as wood macerates were prepared and mounted unto microscopic slides using standard anatomical methods. All the species had diffused porous wood, heterogeneous rays, aseptate fibres and predominantly solitary vessels with simple perforation plate, few pore clusters and pore multiples. Banded paratracheal axial parenchyma was common in all taxa except in A. senegal which was predominantly paratracheal without bands. Multiseriate rays were common features in all taxa except in A. nilotica which had predominantly uniseriate rays. Quantitative wood anatomical characters such as fibre length, fibre diameter, fibre lumen diameter, fibre wall thickness, vessel length, vessel diameter, ray length, ray diameter and pore diameter were of taxonomic importance in the delimitation of the studied taxa. The Runkel ratio of A. senegal (0.99µm) compared favourably with some hardwood species in the Nigerian rainforest ecosystem hence this taxon could be exploited for pulp and paper in Nigeria.

Beneficial properties of shade trees of tea plantations other than their medicinal properties have been extensively studied. This research was initiated to explore the properties of some shade trees with special emphasis on their antioxidant and antibacterial properties. Leaves from shade tree like Dalbergia sissoo (DS), Cassia siamea (CS), Derris robusta (DR), Leucaena leucocephala (LL), Acacia lenticularis (AL) and Melia azedarach (MA) were used for the study. Characterization of shade tree leaves by determination of moisture, crude fibre and ash content and tests of non polar – polar solvent extracts for steroid, tannins, cardiac glycosides and coumarin, free radical scavenging, ferric reducing power, NO scavenging activities, quantification of Flavonoids and antibacterial activity were conducted. The average moisture, crude fibre and ash percentage of shade tree plants were found to be 62.95, 11.28 and 1.86 respectively. Methanol, ethanol, acetone and ethyl acetate respectively proved to be the most potent solvent for various phytochemical extractions as it gave positive results for tests like tannin, steroid, cardiac glycosides and coumarin. AL (91.46%), DR (92.69%), LL (94.32%) and MA (93.34%) leaf extracts showed a high level of DPPH scavenging activity in their water extracts. In DS (88.11%) and CS (83.23%) maximum DPPH scavenging activity was observed in Diethyl ether and Methanol extracts respectively. Acetone extracts were more active than the water extracts in exhibiting ferric reducing power and NO scavenging activity. Summation of the quantity revealed that DS showed maximum presence of flavonoids and acetone as most potential for isolation of flavonoids. The decreasing order of summative antibacterial activity was recorded in DS, followed by CS, DR, AL, MA and LL. Chloroform showed the highest summative inhibition zone followed by ethanol, ethyl acetate, diethyl ether, acetone, water, hexane, benzene and methanol. The antioxidant and antibacterial potential of shade trees were established.

An experiment was conducted to estimate the genetic variability and regression analysis for yield and quality traits in a set of eight brassica genotypes in a randomized complete block design with three replications at The University of Agriculture Peshawar, during 2011-12 cropping season. Significant genetic variability was recorded among genotypes for plant height, pods main receme-1, pod length, seed yield plant-1, 1000-seed weight, seeds pod-1, oil content, protein content, glucosinolate content, erucic acid content, oleic acid content and linolenic acid content except for primary branch plant-1 and pods plant-1 which showed non-significant differences. Genotypes, AUP-401, AUP-402, AUP-404 and AUP-407 showed potential performance for glucosinolate content (55.1 μmol g-1), seed yield plant-1 (23.93 g), pods plant-1 (268.83), protein contents (21.1 %), erucic acid contents (42.7 %) and oil contents (53.3 %). Seed yield plant-1 was taken as a dependent variable to study the effects of many morphological yield traits on it. Branches plant-1, pods main raceme-1, pods plant-1, and seed pod-1 showed a positive effect on seed yield plant-1, while 1000-seed weight, pod length, and plant height showed a negative effect on seed yield plant-1. Seed yield plant-1 as an independent variable showed a negative effect on oil content. Protein content as an independent variable showed a positive effect on erucic acid content, while oil contents as independent variables show a negative effect on protein contents, respectively. The developed germplasm could be used in the upcoming brassica breeding programs to release high yielding, disease resistance, stress tolerance, and insect resistance varieties, which will eventually upsurge the productivity and decrease the gap between demand and domestic production of the brassica crop.

Lentil is (Lens culinaris Medik.) also popularly known as Masur which is extensively grown in Bangladesh for its economic importance. It is the second most important pulse crop both in acreage and production but stands first in consumer’s preference in Bangladesh [1]. Lentil is considered as poor mean’s meat, a substitute of animal protein for the underprivileged people of Bangladesh who cannot afford to buy animal protein [2,3]. It is an excellent source of carbohydrates, vitamins, minerals and several essential micro-nutrients like iron, zinc and betacarotene [4,5,6]. The crop has great significance in cereal-based cropping systems because it can fix atmospheric nitrogen and thereby enriching the soil by Rhizobium bacteria [7,8]. Recently, lentil has received considerable interest by the scientific community due to its higher nutritive value and lower seed yield plant-1. Increasing yield is therefore the prime breeding objectives of lentil breeder around the globe including Bangladesh. Low production and acreage of lentil in Bangladesh is due to the shortage of lentil varieties with high yield, poor technological intervention during production and competition for a place in the existing cropping pattern. This lacking can be overcome by developing high yielding varieties with wider adaptability and stability.
