Determination of Fruit Chemical Properties of Morus Nigra L., Morus Alba L. and Morus Rubra L. by Hplc
(Elsevier, 2011) Gundogdu, M.; Muradoglu, F.; Sensoy, R. I. Gazioglu; Yilmaz, H.
This study was carried out to determine the organic acid content, phenolic compound content, sugar content. vitamin C (ascorbic acid) content and total antioxidant capacity of white mulberry (Morus alba L), black mulberry (Morus nigra L.) and red mulberry (Morus rubra L) fruits grown in Van province of Turkey. It was determined that the chief organic acid in these mulberry species was malic acid ranging from 1.32 to 4.47g 100 g(-1) fw, followed by citric acid ranging from 0.39 to 1.08g 100g(-1) fw. Looking at the contents of phenolic compound, chlorogenic acid and rutin had come to the fore ranging from 0.12 to 3.11 mg g(-1) fw and from 0.85 to 1.42 mg g(-1) fw, respectively. Fruit glucose contents of the studied species were higher than their fructose contents, varying between 6.07 and 7.75g 100 g(-1) fw. Total antioxidant capacity and vitamin C contents of the mulberry species ranged from 4.49 to 13.99 mu mol TEg(-1) fw and from 11.30 to 24.42 mg 100 g(-1) fw, respectively. (C) 2011 Elsevier B.V.

Determination of Pomological and Biochemical Properties of Local Pomegranate (Punica Granatum L.) Cultivars
(int Soc Horticultural Science, 2015) Gundogdu, M.; Kazankaya, A.; Muradoglu, F.; Tufenkci, S.; Encu, T.; Sensoy, R. I. Gazioglu
Pomegranate is among the important fruit species for human health and diet for centuries. It is stated in the recent studies that pomegranate is widely used for medicinal purposes, which promotes its preference. In the present study, some pomological and biochemical properties of the eighteen local pomegranate genotypes widely grown in Mardin Province of Turkey were determined. It was determined that the 'DAHL-1' local cultivar had the highest fruit weight (327.45 g) and fruit juice volume (138 ml). The seed weight, soluble solid content, and pH contents of the investigated cultivars ranged from 45.7 to 167.4 g, 10.75 to 16.75 degrees Brix, and 3.11 to 3.98, respectively. Moreover, some other criteria such as fruit juice acidity, fruit size, calyx dimension, seed hardiness, and seed size, shape index, fruit taste were also determined. In the results of analysis, the genotype 'DAHL-1' had more advantageous than the others based on the fruit attractiveness, fruit size, fruit juice volume and other criteria.
Effect of Jasmonic Acid on Germination Dormant and Nondormant Apple Seeds
(Chemical Publishing Co., 2007) Yildiz, K.; Yazici, C.; Muradoglu, F.
Jasmonic acid clearly stimulated germination of dormant apple seeds. However, in the seeds stratified for 30 and more days, some concentration of Jasmonic acid seemed as inhibiting, generally, Jasmonic acid was found ineffective. The treatment of seeds with Jasmonic acid not only increased germination level, but also accelerated germination of dormant seeds according to control seeds. On the other hand, Jasmonic acid delayed the germination of seeds stratified for particular period. The retarding effect of Jasmonic acid on germination was clearer in seeds stratified for 90 d. Although Jasmonic acid stimulated germination some degree, but it did not found as effective as stratification under cold condition in removal of dormancy in apple seeds.
The Effect of Jasmonic Acid on Germination of Dormant and Nondormant Pear (Pyrus Communis L.) Seeds
(Ista-int Seed Testing Assoc, 2008) Yildiz, K.; Muradoglu, F.; Yilmaz, H.
Jasmonic acid (JA) stimulated germination of dormant pear (Pyrus communis L.) seeds. Treatment of seeds with JA not only increased germination level, but also accelerated germination of dormant seeds according to control seeds. However, in the seeds stratified for 30 and more days, JA did not change total ratio of germination, but delayed the germination. The retarding effect of JA on germination was larger in seeds stratified for 90 days. Although JA stimulated germination to some degree but it was not as effective as stratification under cold condition in removal of dormancy in pear seeds.
Fruit Sets and Fruit Drops in Turkish Apricot (Prunus Armeniaca L.) Varieties Grown Under Ecological Conditions of Van, Turkey
(Asian Network for Scientific Information, 2007) Fikret Balta, M.; Muradoglu, F.; Askin, M.A.; Kaya, T.
This research was conducted to determine fruit sets and fruit drops from full bloom to harvest in Turkish apricot varieties for two years. In the study, changes in fruit sets and fruit drops following full bloom period in apricot varieties were assessed in eight different dates in the first year and in eleven different dates in the second year. In 2004, the final fruit sets were determined a few days before harvest time (13 July) as 24.5% in Soganci, 34.9% in Hasanbey, 41.3% in Alyanak, 45.5% in Tokaloglu, 31.1% in Salak and 35.1% in Sekerpare. The final fruit sets at the harvest time of 2005 were found as 4.5% in Soganci, 19.8% in Hasanbey, 15.6% in Alyanak, 31.1% in Tokaloglu, 20.1% in Salak, 20.4% in Sekerpare, 7.1% in Hacihaliloglu, 12.6% in Kabaasi and 21.7% in Sakit. © 2007 Asian Network for Scientific Information.
