Anatomical and Histological Investigations on the Effects of Stratification Substrates on Final Take and Quality of Grafted Vines
(TUBITAK, 2000) Cangi, R.; Balta, F.; Doǧan, A.
This experiment was carried out to determine the effects of water, sawdust and pumice as stratification substrates on the success of callusing, final take and quality of grafted vines of the Hafizali and Ercis, grape cultivars grafted on Kober 5BB rootstock. The anatomical and histological development of the graft union was investigated at 21, 28, 35 and 42 days after grafting in all combinations. As for the results of the anatomical and histological investigations, it was observed that the cambial continuity between graft components in all combinations was mostly established in 21 days, and completed in 28-35 days in water and sawdust. Although water and sawdust were found to be better than pumice, water is recommended as the optimum stratification substrate.
Effect of Humic Acid Applications on Yield, Fruit Characteristics and Nutrient Uptake in Ercis Grape (V. Vinifera L.) Cultivar
(Chemical Publishing Co., 2006) Cangi, R.; Tarakcioglu, C.; Yasar, H.
The effects of humic acid applications on the yield, fruit characteristics and nutrient uptake of Ercis grape cultivar (V. vinifera L.) in Van in the east of Turkey were examined during two growing seasons in 2003-2004. Solid form of humic acid (55% humic acid, 30% fulvic acid and 8% K2O) were applied from soil in the amount of 100, 200, 300 kg/ha and 10, 20, 30 kg/ha from leaves. There was no significant effects of humic acid application on the yield and mean bunch weight (MBW) but there was significant effect on soluble solid contents (SSC) and total acid statistically. SSC content was increased with humic acid applications, but total acid was decreased with treatment. As a result of this study, yield, MBW, SSC total acid ranged between 6650 and 14580 kg/ha, 123.3 and 249.5 g, 12.3 and 18.0%, 1.28 and 2.05 g/L, as years and applications, respectively. In the result of leaf analysis, humic acid affected the N content (each two years), P, Fe and Zn contens of leaves (at first year), but K, Cu and Mn contents were not affected statistically. N and K content of leaves were increased with humic acid applications as compared with control. As a result, SSC, total acid, N and Fe contents of leaves of grape vines were affected by humic acid application. In cool ecology, such as Van province, increase in SSC by humic acid application will contribute to ripening of grapes before autumn frost.
Effects of Crown Gall (Rhizobium Vitis) Disease on Physical and Biochemical Characteristics of ‘narince’ (Vitis Vinifera L.) Grape Berries
(International Society for Horticultural Science, 2020) Yagci, A.; Keskin, N.; Sucu, S.; Kunter, B.; Cangi, R.; Altinci, N.
Crown gall (Rhizobium vitis) is an economically important disease affecting growth of grapevine (Vitis vinifera L.). But the effects of the disease are generally focus on the lack of vine vigour rather than chemistry of berry content. In this study, impacts of crown gall disease on fruit yield and berry quality were investigated in the white wine grape cultivar ‘Narince’ planted in a commercial vineyard. ‘Narince’ vines showing symptoms and non-symptoms were compared. An equal number of 15 vines were evaluated in each group. Juice from grapes were collected at five stages of berry ripening after the onset of veraison. Number and total weight of clusters and berries were collected at the time of commercial harvest. Data on berry quality attributes (total soluble solids measured as °Brix, pH, titratable acidity, and some phytochemical characters) were investigated in grape samples of symptomatic and non-symptomatic vines. Descriptive analysis was realised by variance analysis and the test of Duncan. © 2020 International Society for Horticultural Science. All rights reserved.
Some Pomological and Biochemical Properties of Rose Hip (Rosa Spp.) Germplasm
(int Soc Horticultural Science, 2015) Celik, F.; Kazankaya, A.; Dogan, A.; Gundogdu, M.; Cangi, R.
This study aimed to select superior rose hip genotypes among the germplasm naturally distributed in the province of Van (Muradiye and Caldiran towns) (in the Eastern Anatolia Region of Turkey) and to determine the biochemical and pomological properties of these genotypes in 2009 and 2010. In the first year of the study, 500 rose hip genotypes were marked in order to be investigated. Based on the results of chemical and pomological analysis, 20 genotypes were reexamined in the following year. Based on the results of two years of physical and chemical analyzes among the 120 rose hip genotypes, the superior genotypes were selected by a weighted ranking scale. Based on the weighted ranking scale, the 16 rose hip genotypes (M04, M11, M16, M29, M40, M54, M55, M61, M67, M72, C89, C90 C101 C106, C107, and C113) having highest scores were selected for their superior traits. Among these selected genotypes, fruit weight ranged from 2.43 to 4.88 g; fruit length varied from 21.48 to 26.27 mm; fruit width varied from 13.04 to 16.51 mm; fruit flesh percentage ranged from 49.10 to 76.20%; soluble solid content varied from 17.20 to 23.00 degrees Brix; vitamin C content ranged from 582.24 to 711.09 mg/100 g; total dry matter content varied from 45.70 to 53.26%; titratable acidy ranged from 2.04 to 3.61%; and pH varied from 3.03 to 4.15. Moreover, there were 2 thornless, 5 low-thorny and 9 thorny genotypes among the selected among the 16 rose hip genotypes.
