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

Indonesian Tropical Fruit Research Institute (ITFRI) known as an institute collecting exotic tropical fruits in Indonesia. The present study was carried to evaluate the characters of five exotic fruits in the Indonesian Tropical Fruit Research Institute (ITFRI), Solok, West Sumatra, Indonesia. The experiment used field observation. The characters considered were leaf character (leaf shape, leaf margin, leaf tip, leaf base, the color of upper leaf, color of under leaf, leaf surface, leaf length, leaf width), and fruit character (fruit shape, fruit peel texture, fruit length, fruit width, fruit weight, the color of mature peel, the color of mature flesh, taste, fruit weight, seed weight, seed number). Data were analyzed descriptively using tables. The five exotic fruits' morphological characteristics have demonstrated that every species of fruit has specific characteristics. These fruits have the potential to be raw materials for the pharmacy industry.

The taxonomic identities of some Capsicum varieties are somewhat controversial. This study is aimed at using morphological characters to ascertain the Capsicum species to which variety accuminatum belongs. The study was conducted at the Experimental Plot of the Department of Pure and Applied Botany, Federal University of Agriculture, Abeokuta (Latitude: 7.214952; Longitude: 3.437090) using a Randomized Complete Block Design (RCBD) in 10 replicates. Quantitative and qualitative characters were evaluated through measurements and visual observation respectively. Data were analyzed using Statistical Analysis Systems version 9.2 and Duncan's Multiple Range Test was used to separate means at p ˂ 0.05. The reults revealed erect growth habit, lanceolate leaf shape, pendant flower position, white corolla colour, obtuse fruit shape at pedicel, elongated fruit shape, and pointed fruit shape at blossom end on variety accuminatum as characteristic features of C. frutescens. Plant canopy width 103.41±(4.30) cm, number of branches per plant 24.70±(0.15), days to flowering 73±(0.21), fruit length 11.69±(0.07) cm and fruit width 5.78±(0.05) cm in variety accuminatum are closer to mean values in C. frutescens. This study showed that variety accuminatum is morphologically and evolutionary related to C. frutescens. Therefore, re-naming of C. annuum var. accuminatum is hereby suggested and proposed to be C. frutescens var. accuminatum.

Fifty nine morphological characters and isozyme band patterns of glutamate oxaloacetate transminase, peroxidase, glucose phosphate isomerase from fully expanded leaves were used for taxonomic study on 51 taxa consisted of Korean native and principal cultivars of the genus Pyrus. Taxonomic relationships were analyzed by complete cluster analysis method based on Euclidean taxonomic distance of IBM PC SPSS/PC+(ver. 3.0). Among the 39 qualitative morphological characters, a great deal of variations among 51 taxa were observed in immature fruit shape, skin lusterness, hair density on pedicel, anther color, shape of leaf apex and base, hair density on leaf surface, and leaf margin. Considerable variations were found in most tested quantitative characters except in the number of petals and styles. More reliable taxonomic results could be obtained by comparing morphological characters rather than examining isozyme band patterns. Even though there were considerable differences depending upon the methods of investigation, classification of the genus Pyrus by using isozyme band patterns was proved to be a good tool for rapid taxonomic studies.

ABSTRACT The Eggplant (Solanum melongena L.) is one of the plant commodities that has high economic value. Eggplant production is still volatile so plant breeding with a colchicine mutation is needed to increase eggplant production. Colchicine is Colchicum autumnale seed extract which is able to weaken the spindle thread from the metaphase process to anaphase so that chromosome multiplication occurs without the formation of cell walls. Eggplant sprouts induced by different concentrations of colchicine, they are 0 ppm (K0), 100 ppm (K1), 200 ppm (K2) for 6 hours (L1), 12 hours (L2), 18 hours (L3) . The variables observed were morphological characters such as plant height, flowering age, fruit weight, fruit diameter, fruit length, leaf length, leaf width and stem diameter. The results of the treatment show concentration of colchicine and soaking time had a very significant effect on fruit diameter and fruit weight. K1L2 is the most effectif treatment on diameter and weigh of fruit.The concentration of colchicine has a significant effect on plant height and flowering age. The most effectif concentration in plant height and flowering age is K1. Keywords: Eggplant, Colchicine concentration, Soaking time of colchicine ABSTRAK Terung (Solanum melongena L.) merupakan salah satu komoditas tanaman dengan nilai ekonomis tinggi. Produksi terung masih fluktuatif sehingga pemuliaan tanaman dengan mutasi colchicine diperlukan untuk meningkatkan produksi terung. Colchicine merupakan ekstrak dari biji Colchicum autumnale yang mampu melemahkan untaian DNA dari proses metafase menjadi anafase, sehingga multiplikasi kromosom terjadi tanpa pembentukan dinding sel. Kecambah terung diinduksi dengan colchicine dalam konsentrasi yang berbeda, yaitu 0 ppm (K0), 100 ppm (K1), 200 ppm (K2) selama 6 jam (L1), 12 jam (L2), 18 jam (L3). Variabel yang diamati adalah karakter morfologi seperti tinggi tanaman, umur berbunga, berat buah, diameter buah, panjang buah, panjang daun, lebar daun dan diameter batang. Hasil percobaan menunjukkan konsentrasi colchicine dan waktu perendaman memiliki pengaruh yang sangat signifikan terhadap diameter buah dan berat buah. Perlakuan K1L2 merupakan perlakuan yang paling efektif mempengaruhi diameter dan berat buah. Konsentrasi colchicine memiliki efek signifikan terhadap tinggi tanaman dan usia berbunga. Konsentrasi paling efektif terhadap tinggi tanaman dan umur berbunga adalah K1. Kata Kunci: Terung, konsentrasi colchicine, waktu perendaman colchicine

The olive trees (Olea europaea L.) have been cultivated for millennia in the Mediterranean basin and its oil has been an important part of human nutrition in the region. In order to distinguish between olive accessions, morphological and biological characters have been widely and commonly used for descriptive purposes and have been used to characterize olive accessions. A comparative study of morphological characters of olive accessions grown in Tunisia was carried out and analyzed using Bayesian Networks (BN) and Principal Components Analysis (PCA). The obtained results showed that averages of fruit and kernel weights were 2.27 grams and 0.41 grams, respectively.  Besides, a relatively moderate level of variation (51.22%) being explained by four Principal components. BN revealed that geographical localisation plays a role in the increase of tree habit, size of lenticels and leaf shape. A dendrogram has been carried out in the aim to classify studied olive accessions. We proposed a novel method of analysis based on the three-step scheme, in which first the data set is clustered, then olive tree features are evaluated. The studied accessions can be divided into four main groups by cutting the dendrogram at a similarity value of 0.645. Different relationships are studied and highlighted, and finally the collected features are subjected to a global principal component analysis. Obtained results confirmed that core surface was negatively correlated with geographical location (r = -0.52, p<0.05) and maturation period r = -0.539, p<0.05). Number of lenticels was positively correlated to lenticels size (r = 0.632, p<0.05). Core shape had a negative correlation with fruit shape (r = -0.759, p<0.05). On the basis of these findings, this research confirmed that morphological markers are a preliminary tool to characterize olive oil accessions.

Background. The studied population of Prunus pumila L. has been introduced into Chelyabinsk Province, as its natural area of distribution is in North America. Of interest for researchers is the introduced population’s variability, induced by the effect of soil and climate factors natural for its new habitat.Materials and methods. A collection of 197 plants was employed to study the variability of P. pumila. Morphological characters were described in compliance with atlases dedicated to seed and fruit descriptive morphology, with some adjustments concerning specific features of the subfamily Prunoideae Focke. The confidence interval for means was calculated using the reliability criterion of t2 = 2.576. The degree of variation was assessed for the studied characters according to S. A. Mamaev’s scale.Results and conclusion. The average fruit weight was 2.49±0.11 g and varied from 1.25 to 5.15 g. The average stone weight was 0.25±0.01 g. Out of the number of morphometric traits, almost all linear characters of fruit and stone size had low variability (coefficient of variation [V]: 8–12%). Of those linear characters, only the peduncle length showed medium variability (V = 13–20%). The stone weight also had medium variability, while the fruit weight demonstrated high variability (V = 21–30%). The fruit shape was subglobose (40.3%), less frequently ovate (20.9%), ovoid (20.9%), broadly ovoid (9.7%), cordate (6.1%) or elliptic (2.0%). The ventral suture was usually barely noticeable, less frequently moderately (3.1%) or strongly expressed (1.0%). Polymorphism was observed in the pulp color, which was usually green-pink (72.8%). The P. pumila stone shape was elliptic (38.1%) or subglobose (34.0%), less frequently prolate (10.7%), ovoid (13.2%) or obovate (4.1%). The stone was symmetrically shaped from the ventral suture and sides, usually looking subglobose from the sides. The shape of the stone’s apex was rounded (85.3%) or, less frequently, obtusely mucronate (15.7%); its base was rounded (80.7%), often attenuate (15.7%), less frequently slightly slanted (3.6%). The stone surface texture was smooth (57.4%), often slightly costate (36.5%). There were several cases of a more costate surface of the stone (6.1%). Thus, the introduced population was found to have broad polymorphism of morphological characters in the fruit and the stone. A considerable increase was observed in morphometric indicators, including the size of fruit and stone, compared with those typical for the species in natural environments, which may be of special significance for breeders. The fusiform shape of the stone, characteristic of var. depressa Pursh. in its natural habitat, was absent in the introduced population.

Fruit quality is a very important objective because the consumers have increasing demands for high quality plums, where as it depends of the morphological and organoleptic characteristics of the fruit (shape, size, background color and coverage, color and consistency of the pulp, juiciness, taste, flavor, etc.), as well as technological, biochemical and nutrition value of them. Fruit size is expressed most often by weight or fruit diameter. The study took place in two fruit-growing ecosystems Călacea-Sălaj County and Cluj-Napoca County (at Agroindustriala fruiting tree farm) respectively, and were analyzed 7 varieties of plum in total. Determinations regarding the influence of thinning have been made for these varieties on fruit weight (g) and fruit diameter (mm). Following the chemical treatments for thinning, the highest percentage of fruit with a diameter bigger than 35 mm, in fruit-growing ecosystem Călacea-Sălaj County, was obtained for Stanley cultivar, after the treatment with Cosavet, while in Cluj-Napoca fruit-growing ecosystem, the highest percentage of fruit with a diameter bigger than 35 mm was obtained also for Stanley cultivar, but after the treatment with Ethrel. The highest fruit weight in fruit-growing ecosystem Călacea-Sălaj County was recorded for Stanley variety, after the treatment with Cosavet products (60.2 g), Sulfomat (49.6 g) and Ethrel (48.28 g); in fruit-growing ecosystem Cluj-Napoca, the highest fruit weight was recorded for Nectarină Roșie variety, after the treatment with Cosavet products (57.8 g) and Sulphur (57.8 g).
