Investigations on the Pollen Morphology of Some Fruit Species

WOS: 000266361100010Morphological characters are used to identify plant material. Pollen morphology is an important parameter. This is of great importance in detailed investigations by scanning electron microscope (SEM). In order to develop a plant material identification tool, this research was carried out to determine the pollen morphology of some fruit species using SEM on apple, pear, quince, apricot, plum, peach, almond, chestnut, walnut, pomegranate, and persimmon cultivars. The surface features, as well as length, width, and P/E ratio of pollen were observed. Pollen length and width changed with investigated species and cultivars; the longest and widest pollen grains were detected in peach and walnut, respectively. The pollen. according to P/E ratio, was prolate. suboblate. and perprolate based on the material. Regarding the surface features. the ornamentation of pear, quince. plum, peach, and almond pollen was striate and tectum perforatum, whereas that of apple, chestnut, apricot and pomegranate was striate, rugulate, and tectum imperforatum. Walnut and persimmon had special surface characteristics

Leaf phenolic content of some squash rootstocks used on watermelon (Citrullus lanatus (thunb.) Matsum and Nakai) growing and phenolic accumulation on grafted cultivar

WOS: 000277860700022In this study, phenolic compounds were identified in the leaves of grafted and non-grafted watermelon (Citrullus lanatus (Thunb.) Matsum and Nakai) plants and squash rootstocks. The watermelon cultivar 'Crispy' was grafted onto hybrids of C. maxima x C. Moschata, 'TZ-148' and 'RS-841', and Lagenaria siceraria cv. '64 - 18'. The experiments were conducted in a randomized complete blocks design in two time periods. Non-grafted plants were used as the control. Some important differences were detected for the contents of the phenolic compounds during the growing periods such as kaempferol accumulates in the leaves of grafted and non-grafted watermelon plants and rootstocks. Kaempferol contents of the rootstocks were found to be higher than the grafted and non-grafted watermelon plants. Plants grafted on 'TZ-148' or 'RS-841' had higher phenolic content than the others

Investigations on fertilization biology and description of fruit characteristics of some persimmon (Diospyros kaki) cultigens

WOS: 000292258100015Persimmon is a fruit that has increasing importance on export and prefer to be consumed because its taste, nutrient content and appearance. It can be grown at different ecological conditions without discerning climate and soil. In this sense, it is important to encourage persimmon cultivation. Pollinators need to be used for a good fruit set on cultural varieties. In this study that prepared from this point of view, fertilization biology, phenological and pomological observations were performed on Hachiya and Fuji cultivars that pollinated with different male types in demis/Izmir-Turkey. Additionally, viability (TTC and IKI) and germination tests were carried out. Consequently, it was observed that fruit set increased when pollinators were used.Ege University Scientific Research Project OfficeEge University [2006-ZRF-006]This paper was prepared from the project (2006-ZRF-006) funded by Ege University Scientific Research Project Office

FRUIT CHARACTERIZATION AND EVALUATION OF F-1 HYBRIDS IN HACIHALILOGLU X IVONNE LIVERANI COMBINATION

WOS: 000550823500003Apricot is a type of fruit with high consumer demand because it is evaluated as table and dried. Different eco-geographic groups have varieties with superior characteristics. This situation is very important in terms of creating wide variations in breeding studies. in the current research, pomological and biochemical properties of 45 apricot hybrids obtained from the parental combination of Hacihaliloglu X Ivonne Liverani were analyzed and identified. Variation was determined related to investigated characteristics among apricot genotypes. the data were evaluated by PCA (Principal Component Analysis) and CA (Clustering Analysis) upon determining the correlation between properties. 10 PCA were obtained, and they defined 78.12% of the population with 27 characteristics. the highest correlation was stated between fruit weight and width. Hybrids were with small sized, orange color, free and sweet kernel. the organoleptic properties of most hybrids are at acceptable levels

Analysis of Fruit Properties of 'Hacihaliloglu' x 'Boccucia' Hybrid Population

WOS: 000515911600001Apricot is an important fruit species cultivated in the world. Different varieties of apricot with various quality and sensory characteristics that vary according to the countries are consumed. It is important to breed new varieties to meet consumer demands. Therefore, in this study that was conducted with the 'Hacihaliloglu' x 'Boccucia' population to develop new varieties at a later stage, physical, chemical sensory characteristics of the hybrid population were investigated and the status of the population through PCA (Principal Component Analysis) and CA (Clustering Analysis) upon determining the correlation between properties evaluated. Significantly, high levels of variation were observed regarding fruit weight, color, firmness and harvest time. Fruit color and harvest time have been distinctive parameters in selecting genotypes. the dendrogram obtained from cluster analysis grouped 20 genotypes in the same group while the other genotypes were placed in a separate group

Determination of Antibacterial Effect of Different Plant Essential Oils Against Erwinia amylovora

WOS: 000490344100004Fire Blight caused by Erwinia amylovora is a disease of plants belonging to Rosaceae family of 39 different genera and 128 species. Integrated disease management is preferred by combining different methods in the disease control. Nowadays, studies on alternative methods to control of the disease were intensified. One of these methods is using of essential oils obtained from medical and aromatic plants. In this study, antibacterial activity of 16 different plant essential oil was investigated against to Erwinia amylovora in vitro conditions. Seven essential oils (Allium sativum, Cinnamomi ceylanici, Cymbopogon citratus, Lavandula officinalis, Mentha arvensis, Syzygium aromaticum and Thymus vulgaris) inhibited successfully the growth of Erwinia amylovora in vitro conditions. The higher antibacterial efficacy was produced by the six plant essential oil except Cymbopogon citratus, compared to streptomycin. Essential oils from A Ilium sativum, Cinnamomi ceylanici and Mentha arvensis were obtained in 16.44, 15.11 and 12.94 mm inhibition zones, respectively and these essential oils had the highest antibacterial effects. These effective essential oils was found as promising in this disease control

An Analysis on Some Reciprocal Pear Hybridization Combinations in Terms of Transferring Resistance to Fire Blight

ALTAY, Yasin/0000-0003-4049-8301; Mertoglu, Kerem/0000-0002-0490-9073;WOS: 000510269500001Since it has a wide variety, pear can be grown in all temperate zones and high-altitude areas of tropical and subtropical climates of the Earth. on the other hand, most of the cultured pear varieties are susceptible to fire blight caused by Erwinia amylovora, and their susceptibility is threatening pear cultivation. the lack of a certain solution to fire blight, the harmful effects of the chemicals on environment and human health and the increasing demand for organic products, give priority to breeding new resistant rootstocks and varieties in control of the disease. Due to the polygenic nature of fire blight resistance and the complexity of its mechanism, controlled hybridization is generally used in breeding programs. in order to determine the effect of the parents for the transmission of fire blight resistance, hybridizations are also carried out reciprocally. in the study which was carried out for this aim, susceptibility levels of the F1 hybrids, obtained from the reciprocal combinations of fire blight resistant 'Kieffer' and the susceptible 'Williams', 'Santa Maria' and 'Akca' cultivars, were evaluated. While 'Kieffer' x 'Santa Maria' was found the most resistant combination to fire blight, 'Akca' x 'Williams' was found as the most susceptible one. in addition, it has been determined that F-1 hybrids obtained from 'Kieffer' x 'Santa Maria' and 'Akca' x 'Williams' hybridization combinations and their reciprocals are different in terms of disease resistance, while there was no difference in resistance in F-1 hybrids of 'Williams' x 'Santa Maria' combination and its reciprocal combination.TUBITAKTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [TOVAG 110O938, TOVAG 106O719]We would like to thank TUBITAK for funding the projects that the study material obtained (TOVAG 106O719 and TOVAG 110O938)
