Neolamarckia cadamba (Kadam) genetic resources were characterised Distinctness, Uniformity and Stability (DUS) traits based on International Union for the Protection of New Varieties of Plants12 guidelines. Twenty-five clones of kadam were characterised based on the morphological characters of leaf and bark with 12 descriptors. Among these 12 descriptors, 9 were qualitative traits viz., leaf shape, Leaf base shape, apex shape, leaf margin, leaf venation, base symmetry, Waxiness in upper side of leaf, bark colour and bark texture and 3 were quantitative characters viz., leaf length, leaf breath, leaf petiole length. The study exhibited significant variations among the genetic resources investigated for various DUS traits, which could act as reference traits for developing variety to protect the genetic resources through Intellectual Property Rights.

ABSTRACT Although mango is one of the tropical fruits of greater interest in the world trade, literature concerning their rootstocks (characteristics and utilization) is scarce. This study aimed to characterize mango plants from cv. Imbú, widely used as rootstock in the Zona da Mata region, State of Minas Gerais (MG), Brazil. Though fruits of this cultivar do not present desirable commercial characteristics, this study allowed us to characterize part of plant morphology and fill a gap in the literature, providing subsidies for future investigations. For such, 'Imbú' plants (˜ 4-years old) from the collection of the Universidade Federal de Viçosa, located in Viçosa -MG were evaluated. The descriptors were: (i) leaf blade division;(ii) leaf composition; (iii) petiole length in relation to leaf blade; (iv) phyllotaxis, (v) leaf position in relation to the branch insertion; (vi) leaf shape; (vii) leaf apex and base angles; (viii) leaf margin category; (ix) venation; (x) leaf length and thickness; (xi) leaf length/thickness ratio; (xii) leaf texture; (xiii) leaf fragrance; (xix) leaf color. The leaves were depicted as lanceolate, with entire margins and sharp angles at the base and apex of the leaf blade. The intensity of the green color of the leaf blade was considered intermediate and the abaxial surface staining showed less intense than that observed in the upper side. The fruits were processed and separated into peel, pulp and seeds in order to evaluate the flesh color, fresh weight and percentage of seeds, peel and pulp. It was determined the soluble solids content, starch concentration, the peel and the pulp color, the cerosity, the percentage evaluation of peel, pulp and seed and the pulp firmness. The average number of germinated seedlings per seed was estimated for 230 sown seeds.

Peristylus goodyeroides is a terestrial orchid that scattered around Southeast Asia. Morphological characters of P. goodyeroides can vary, depending on the ecological factors and habitat. Cytological characters in the form of chromosome configurations can be used as a taxonomic tool for the process of identifying and understanding variations in taxa. The purpose of this study was to determine the morphological characters and chromosome configuration of the P. goodyeroides from Curug Setawing, Kulonprogo. The method used was morphological characterization and plant chromosome preparation by squash method with the main steps of fixation, maceration, staining and observation. Data were analyzed with the help of Image raster 3, Corel Draw X7, and Microsoft Excel 2013. P. goodyeroides from Curug Setawing has the morphological characters of root tubers, cylindrical stems, ovate leaf shape, convolutive leaf arrangement and creamy white flowers. The orchid has a number of chromosomes 2n = 10 with a karyotype formula of 2n = 2x = 8m + 2t. Metacentric chromosomes are found on chromosomes 1-8 and telocentric chromosomes 9-10. The absolute arm length of the chromosomes has a range of 2.03-3.44 μm, the relative arm length of the chromosomes is 2.21-3.32 μm, the length of the p arm is 1.13-1.58 μm and the q arm is 1.23-2.12 μm.

<p><em>Salvia multicaulis</em> is a widespread species of Lamiaceae family in Iran. There are many discussions about its infraspecific variations. Although some varieties were definite for this species in various parts of the world, no infraspecific taxon was reported in Iran and all samples of this species were named as S. multicaulis. In this study, morphological characteristics of S. multicaulis populations, naturally growing in Iran, was examined. Twenty-two traits were examined in 94 individuals of this species to<br />identify their phenotypic difference. Most of the investigated features were showing a high degree of variability, but it was highly pronounced for some characteristics such as basal leaf shape, basal leaf width, basal leaf length/ width ratio and basal petiole length. Significant positive/negative correlations were observed between some morphological variables. Furthermore, significant negative correlations were found between the eastern distribution of populations with basal leaf petiole length and basal leaf length/ width ratio. Based on the UPGMA cluster analysis, populations were divided into two main branches. The first branch contained four populations, while the second branch was bigger and clustered in two sub-branches. In one of them,<br />three populations and in another one the rest populations arranged in two groups. CA joined plot confirmed that each of studied populations or group of populations had distinct morphological trait(s), which were useful in identification of them. Our findings supported population no. 13 had unique morphological traits such as the largest bracts and basal leaf petiole, highest flower number of each inflorescence cycle, widest and largest calyx. The conservation of the highly diverse populations of<br />Iranian S. multicaulis is recommended.</p>

Eight morphological characters of leaves were examined in 2-year-old trees of 25 provenances of Eucalyptus camaldulensis Dehn, grown in a replicated trial in Zambia. Provenances differed significantly in leaf length and width, base angle, and oil gland density but significant effects were attributed to trees within provenances. Leaf curvature also varied between provenances, trees, and branches. The tip angle and the number of veins did not vary significantly. Leaf length and oil gland density were related to maximum temperature at seed source rather than to latitude but the reverse occurred for leaf width. Significant amounts of variation were explained by a linear combination of temperature and latitude but not by longitude, altitude, or rainfall. Information on seven traits was combined in principal component analysis in which the first component (a measure of leaf shape) accounted for 36% of total observed variation while the second (weighted largely on leaf length) accounted for 26%. Mapping of both univariate and multivariate results indicated that there are two major ecotypes and gave some evidence of clinal and ecotypic variation within them. The conclusions support those of other workers both in natural populations in Australia and in exotic populations elsewhere.

Genus Ziziphus (Z.) contains various important species in tropical and subtropical regions that are globally famous for their food and medicinal uses. However, no comprehensive study was available on the morphology and phytochemistry of Ziziphus species, mainly under different growth conditions, i.e., irrigated and desert (Cholistan). Therefore, this study was carried out to evaluate the morphological and phytochemical characteristics of Ziziphus species, i.e., Z. jujuba, Z. mauritiana, Z. spina-christi, and Z. nummularia, found in the irrigated and desert conditions. Our results revealed significant variations for most of the measured parameters, showing a large-scale diversity among Ziziphus species under irrigated and desert conditions. Specifically, Ziziphus species showed better morphology of all measured parameters of leaves and fruits under irrigated conditions compared to desert conditions, indicating that the optimum water availability in irrigated conditions improved the morphological parameters of Z. species. Meanwhile, among all Ziziphus species, the maximum leaf length (7.4 cm), leaf width (4.1 cm), leaf area (30.6 cm2), and leaf petiole length (1.3 cm) were observed for Z. jujuba, and the highest leaf dry weight (55.4%) was recorded for Z. mauritiana. Similarly, the highest fruit length (3.9 cm), fruit stalk length (1.5 cm), fruit diameter (3.6 cm), fruit width (3.8 cm), fruit area (66.1 cm2), seed length (2 cm), and seed diameter (1.1 cm) were measured for species Z. jujuba, while the maximum fruit dry weight (49.9%) and seed width (1.4 cm) were recorded for species Z. nummularia. Interestingly, compared to irrigated conditions, higher values of bioactive contents, i.e., phenol, flavonoid, and antioxidant activity, in fruits and leaves of Ziziphus species under desert conditions indicated the positive impact of desert climate on the phytochemistry of the Z. plants. Among Ziziphus species, Z. nummularia accumulated the maximum fruit phenols (304.4 mg GAE/100 g), leaf phenols (314.2 mg GAE/100 g), fruit flavonoids (123.7 mg QE/100 g), and leaf flavonoids (113.4 mg QE/100 g). Overall, this study demonstrated the significant morphological and phytochemical variations of the Ziziphus species under irrigated and desert conditions, which could be utilized for future studies to improve the production and medicinal potential of the Ziziphus, especially in desert areas.

&nbsp;A population of 1,149 pear individuals from Slovakia is analysed according to their morphological characteristics of fruits and leaves. Three basic taxa were identified &ndash; Pyrus pyraster, Pyrus amphigenea and Pyrus nivalis. Qualitative traits (shape of leaf blade, fruit shape, type of leaf or fruit base, etc.) allowed the exact identification of a particular taxon only in some cases. Quantitative characteristics of leaves proved to be more suitable for the identification of analysed taxa. Statistically significant differences were found between all studied taxa in the values of leaf length and width, and also in the values of relative characteristics that described the leaf shape. Exceptionally the length of leaf petiole had very variable values (S<sub>x</sub><sub>% </sub>= 25.70&ndash;29.75%), therefore it was impossible to classify the species according to this character. Generally, fruit shapes and dimensions are less representative for taxonomy use although significant differences between all studied taxa were found in the values of fruit length. The correct taxonomic classification of pears cannot be done according to one characteristic. It is important to consider a few of them (shape and length of leaf blade or its slenderness, shape quotients and also the shape and length of fruits) for the appropriate classification of pear individuals. &nbsp; &nbsp;

There are not many exhaustive works addressing the agromorphological characterization of traditional fig (Ficus carica L.) cultivars in Spain. In order to analyze the diversity of these fig genetic resources, twelve traditional fig cultivars from the Central-Western Region of Spain were surveyed and characterized agromorphologically. A total of forty descriptors, mainly defined by the International Plant Genetic Resources Institute and the International Union for the Protection of New Varieties of Plants, were used to describe the fruits, leaves and the tree itself over two consecutive years (2013-2014). Some of the cultivars showed distinctive and interesting agronomical characters from a commercial point of view, such as two crops per year (breba and fig), high yields, and fruit quality. This was the case of the fig cultivar widely distributed through the Duero river valley called ?Cuarter?n?. Its fruits were quite heavy and sweet (breba: 93.75 g and 25.91? Brix; fig: 42.41 g and 31.50? Brix), easy to peel, and juicy. Principal component analysis revealed that more than 67% of the agromorphological variability observed was explained by the first three components, some of the breba size parameters (fruit and neck length and fruit width) being the most important factors in differentiating the genotypes. A dendrogram clustered the cultivars into two major groups (unifera and bifera type) and revealed existing synonymies and homonymies. ?Carballar Negra? and ?Moscatel? were the only fig cultivars which did not have breba crops. This work is an important step in the conservation of genetic fig resources in Spain.

Ginseng plant (Phytolacca octandra L.) is a wild plant that has the potential to be used as medicine. The morphological characteristics of ginseng plants in Indonesia are different. Therefore, it is necessary to carry out research aimed at characterizing the morphology and phytochemical screening of ginseng (P. octandra L.) leaves and tubers. The research was conducted first by observing morphological characters and screening phytochemical compounds such as alkaloid test, flavonoid test, phenol test, tannin test, saponin test, terpenoid test, and steroid test. The results of the research on the morphological characterization of ginseng (P. octandra L.) were: having a taproot which was modified into a tuber, a round, smooth, red color, pointed leaf shape, the base and tip of the leaf were pointed, buni fruit type, round flat, colored blackish-purple when ripe, a compound flower is located at the end of the branch and has flat, round seeds. Ginseng tubers have triterpenoid and saponin compounds, while the leaves only have saponin compounds. The potential development of ginseng (P. octandra L.) is currently limited as traditional medicine by local people. This is due to limited knowledge in its development efforts and unknown phytochemical content.

This work was aimed to evaluate genetic diversity among five local and six introduced apple cultivars in the germplasm which located in the South of Syria based on 29 morphological characters of leaf and fruit. The analysis of variance showed significant differences at P < 0.05 for all measured parameters, however the mean values of Limb length and width, fruit weight, length, and width indicated to a wide range of diversity between local and introduced cultivars, that the introduced cultivars have mostly the highest mean value while the local cultivars have the lowest mean values, that clearly found in the local apple cultivar Ksairi (K) which revealed the lowest mean value of fruit weight (FW), fruit length (FL) and fruit diameter (FD) in the comparison with all studied cultivars. Likewise, principal component analysis (PCA) was used and the first 4 principal components accounted for 76.4% of the total variance, with eigen values 29.2%, 18.8%, 16.9% and 11.5% respectively. The main important characters in PC1 are correlated with the high mean value of width of stalk cavity (WP), fruit weight (FW), fruit diameter (FD), fruit length (FL), core length (CL), width of calyx cavity (WC), core width (CW), depth of stalk cavity (DP), stalk diameter (SD), seed width (SeW) and leaf margin (LM). PC2 discriminated among cultivars depending on Fruit shape (FS), leaf shape (LS), over color (OC), maturity time (MT), core shape (CS), limp length (LL) and leaf base (LB) which were able to differentiate between all studied cultivars . PC3 is correlated with the high mean value of Stalk length (SL), titratable acidity (TA), total sugar (TS), and total soluble solids (TSS). PC4 is correlated with the high mean value of depth of calyx cavity (DC), leaf apices (LA) and fruit cross section (FCS). Cluster analysis was also used that divided the studied cultivars into two clusters, the first cluster included all local apple cultivars, in addition to Leaz Golden (LG) cultivar, however AbouGhabra (AG) and Ksairi (K) cultivars revealed the highest similarity, which have the same fruit shape(FS), background color (BC), core shape (CS), fruit cross section (FCS), leaf shape (Ls) and leaf margin (LM). While the second cluster included all the other introduced cultivars.International Journal of Environment Vol.4(4) 2015: 86-99
