    Morphological diversity on fruit characteristics among some selected mulberry genotypes from Turkey
    (2012) Yilmaz K.U.; Zengin Y.; Ercisli S.; Demirtas M.N.; Kan T.; Nazli A.R.
    Turkey has important mulberry genetic resources. In contrast to the other mulberry producing countries, in Turkey mulberry tree is used only for fruit production not for sericulture purposes. Some selected morphological fruit characteristics such as seed formation, fruit weight, SSC (Soluble solid content), titratable acidity, juice yield and pH of 34 selected mulberry genotypes found together in an ex-situ collection parcel in Malatya Fruit Research Institute in Turkey were investigated. The collection parcel has been established in 1996 year with 3×5 m row spacing. The morphological fruit characteristics are represented of 3 years average data (2006-2008). The results showed that there were big differences among genotypes in terms of most of the fruit characteristics. Fruit weight varied from 0.66 (Istanbul dutu 2) to 3.07 (Gumushaci beyaz); SSC varied from 17.33% (Erzincan karadut 16) to 30.67% (Lokum dut); titratable acidity varied from 0.06% (Angut 9) to 1.62% (Gumushaci karadut 8) and pH varied from 2.19 (Kemaliye karadut 9) to 5.86 (Mersin mor dut), respectively.

    Vitamins, flavonoids, and phenolic acid levels in early-and late-ripening apricot (Prunus armeniaca L.) cultivars from Turkey
    (American Society for Horticultural Science, 2013) Gündo?du M.; Kan T.; Gecer M.K.
    This study aimed at determination of vitamin (A, E, C, ?-carotene, and lycopene), phenolic, and flavonoid contents in apricots at different stages of ripening using high-performance liquid chromatography (HPLC). The effect of ripening in terms of phytochemical contents was investigated. Early period apricots showed 2.5 to three times higher level of vitamins (A, E, C, and ?-carotene, and lycopene) in all types of apricots than others (P < 0.05). Early-ripened cultivar, Boccuia, showed the highest level of vitamins, although a higher level of vitamin C was measured in late-ripened cultivar Levent (P < 0.05). No lycopenes were determined in late-period apricots in contrary to early-and middle-period apricots. Levels of phenolics and flavonoids were measured in all types (3-B-Q-D, procyanidin B1, B2, B3, caffeic acid, gallic acid, p-coumaric acid, epigallocatechine, catechine, epictechine, chlorogenic acid, ferrulic acid, and routine) and statistical deviation of all types was noted (P < 0.05). Among all, the cultivar Özal showed the highest level of chlorogenic acid (45,843.00 ?g·g-1 dry matter) in all ripening periods, where middle-ripened cultivar Adilcevaz showed the lowest level of p-coumaric acid (7.93 ?g·g-1 dry matter content base).
