Öğe Cane Quality Determination of 5 BB and 140 Ru Grape Rootstocks(Int Soc Horticultural Science-Ishs, 2008) Dardeniz, A.; Gokbayrak, Z.; Muftuoglu, N. M.; Turkmen, C.; Beser, K.This study was conducted to investigate best cane quality level in 140 Ru and 5 BB grape rootstocks through morphological changes when the canes were sectioned into 4-bud segments from base to tip. Canes were later forced to grow in plastic pots to determine the relationship between cane quality and root-shoot growth characteristics. The results suggested that rootstocks differ along their canes length for best quality to use in propagation. Cuttings should be prepared in 5 BB between 5 to 16(th) internodes, and in 140 Ru between 5-12(th) nodes, because of better quality and well balanced root-shoot growth.Öğe Determination of Cluster Characteristics and Pomological Properties of Selected Clones of 'Elhamra' (Vitis vinifera L.) Grape Cultivar(Int Soc Horticultural Science, 2013) Dardeniz, A.; Seker, M.; Gundogdu, M. A.; Turker, L.; Arda, G.; Kahraman, K. A.'Elhamra' ('Honusu') is a popular cultivar which is grown in all vine production regions in Turkey and extensively in the East Mediterranean and South East Anatolia regions. The cultivar is late maturing and short-pruning. The flowers are functionally female, so the cultivar requires a pollinator. Three different 'Elhamra' clones were evaluated for their cluster and pomological characteristics in 2009 and 2010 harvesting seasons. The genotypes showed differing characteristics for ripening time and fruit parameters as follows: 'Clone 1' has large berries with deep red to violet-black colour, medium to moderate cluster size, tendency to parthenocarpy and is late maturing (through mid-October). 'Clone 2' has large berries with red to violet-black colour, large clusters and is late maturing (mid-October). 'Clone 3' has smaller to medium berries with pinkish green colour, having medium cluster size compared to the other clones, less tendency to parthenocarpy and is very late maturing (through end of October).Öğe Flower Aberrations in Kiwifruit (Actinidia deliciosa)(Eugen Ulmer Gmbh Co, 2011) Engin, H.; Gokbayrak, Z.; Dardeniz, A.The most important problem limiting marketable quality in kiwifruit is the flat or fan shaped fruits. Although selective hand thinning and sorting can be used to remove these fruit, the cost increase may be considerable. This study describes the morphological changes on a microscopic level during flower formation at the reproductive primordia of 'Hayward'. Flower primordia with abnormal deviations were classified into four groups depending upon relative shape (flat or fan-shaped) and the number (double or triple) of the pistil. Normal and flat shaped fruits are similar to each other. Both fruits have a pericarp, mesocarp, seed bed, and core tissue. However, flat fruit has more loculi and wider core tissue. Fasciated fruits form when terminal flower fuses with one or more lateral flower. Double and triple fruit form when two flowers (one terminal and one lateral flower) or three flowers (one terminal and two lateral flowers), respectively, fuse together during ovary differentiation.Öğe Influence of shoot topping on yield and quality of Vitis vinifera L.(Academic Journals, 2008) Dardeniz, A.; Yildirim, I.; Gokbayrak, Z.; Akcal, A.This study was carried out in a 20 year old spur pruned Karasakiz (Kuntra) vineyard during the 2003 and 2004 growth season. Vines were topped at 1, 3 and 5 nodes beyond the last cluster on the main shoot. Yield and quality parameters were analyzed to determine the effects of shoot topping. The results showed that weather conditions had more statistically important effects compared to the topping level. One (1) node topping resulted in more loss of yield due to increased vegetative growth.Öğe Nutrient contents of 140 Ruggeri rootstock canes in dormant season(2011) Türkmen, C.; Dardeniz, A.; Müftüo?lu, N.M.; Gökbayrak, Z.; Kabao?lu, A.This research was carried out to ascertain if there were significant differences in the mineral contents of 140 Ruggeri (140 Ru) canes collected during dormant period. Cuttings of the rootstock 140 Ru prepared for propagation of grafted grapevines were profiled for their mineral contents during two dormant seasons. Cuttings were sampled at four different times starting from leaf fall and divided into five sections. Mineral content changes in the dormant season and along the length of the canes were found to be significant to a limited extent (P value=0.05). The results showed that mineral content in 140 Ru rootstock canes slightly varied with sampling time and sampling section.Öğe NUTRIENT CONTENTS OF 140 RUGGERI ROOTSTOCK CANES IN DORMANT SEASON(Pakistian Agricultural Scientists Forum, 2011) Turkmen, C.; Dardeniz, A.; Muftuoglu, N. M.; Gokbayrak, Z.; Kabaoglu, A.This research was carried out to ascertain if there were significant differences in the mineral contents of 140 Ruggeri (140 Ru) canes collected during dormant period.

This is the first report of the occurrence of star flowers in Turkey. Star flowers were observed in Cardinal (Vitis vinifera L.). The structural features are compared to normal flowers. A genetic analysis using RAPD-PCR was performed to determine if there was a genetic difference between the vines nearing two flower types. There were some minor morphological differences, but RAPD analysis did not show any genetic dissimilarities. Inflorescences appeared more compact on star flowered vines due to shorter pedicels in flowers. Fruit set was also extremely low. This formation is reported in different regions of the world on different cultivars. This might be more common that previously thought. It warrants further research. © 2009 Academic Journals.Öğe Occurrence of star flowers in Cardinal (Vitis vinifera L.) cv.(Academic Journals, 2009) Gokbayrak, Z.; Dardeniz, A.; Soylemezoglu, G.; Kizilcik, S.Star flowers are flowers that differ from normal Vitis flowers in that the calyptra breaks open from the top like the flowers of most other species plants.
