Biological screening of selected flora of Pakistan Biol. Res.
Zia-Ul-Haq,M; Raza Shah,M; Qayum,Mughal; Ercisli,Sezai.
Methanolic extracts of different parts of five medicinal plants, Ferula assafoetidaL. resin, Grewia asiaticaL. leaves, Ipomoea hederaceaJacq. seeds, Lepidium sativumL. seeds and Terminalia chebulaRetz. fruits were tested in vitrofor their cytotoxic, phytotoxic, insecticidal, nematicidal and anthelmintic activities. Ipomoea hederaceashowed very significant phytotoxic and cytotoxic activity, with 100% inhibition of Lemna minorgrowth and 100% death of Artemia salinaat concentrations of 1000 and 100 µg mL-1. Grewia asiaticaexhibited very weak activities while Lepidium sativumand Ferula assafoetidashowed moderate to good potential in all three bioassays. The results suggest screening of Ipomoea hederaceaseeds further for isolation of bioactive compounds that...

Muradoglu,Ferhad; Gundogdu,Muttalip; Ercisli,Sezai; Encu,Tarik; Balta,Fikri; Jaafar,Hawa ZE; Zia-Ul-Haq,Muhammad.
BACKGROUND: Cadmium (Cd) is well known as one of the most toxic metals affecting the environment and can severely restrict plant growth and development. In this study, Cd toxicities were studied in strawberry cv. Camarosa using pot experiment. Chlorophyll and malondialdehyde (MDA) contents, catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) activities and mineral nutrient concentrations were investigated in both roots and leaves of strawberry plant after exposure Cd. RESULTS: Cd content in both roots and leaves was increased with the application of increasing concentrations of Cd. We found higher Cd concentration in roots rather than in leaves. Chlorophyll a and b was decreased in leaves but MDA significantly increased under increased...

Ashraf,Sadaf Naz; Zubair,Muhammad; Rizwan,Komal; Tareen,Rasool Bakhsh; Rasool,Nasir; Zia-Ul-Haq,Muhammad; Ercisli,Sezai.
BACKGROUND: Current study has been designed to evaluate the chemical composition of essential and fixed oils from stem and leaves of Perovskia abrotanoides and antioxidant and antimicrobial activities of these oils. RESULTS: GC-MS analysis of essential oil identified 19 compounds with (E)-9-dodecenal being the major component in stem and hexadecanoic acid in leaves. In contrast, GC-MS analysis of fixed oil showed 40 constituents with α-amyrin the major component in stem and α-copaene in leaves. The antioxidant activity showed the highest value of 76.7% in essential oil from leaves in comparison with fixed oil from stem (45.9%) through inhibition of peroxidation in linoleic acid system. The antimicrobial assay tested on different...

Compositional studies and biological activities of some mash bean (Vigna mungo (L.) Hepper) cultivars commonly consumed in Pakistan Biol. Res.
Zia-Ul-Haq,Muhammad; Ahmad,Shakeel; Bukhari,Shazia Anwer; Amarowicz,Ryszard; Ercisli,Sezai; Jaafar,Hawa ZE.
BACKGROUND: In recent years, the desire to adopt a healthy diet has drawn attention to legume seeds and food products derived from them. Mash bean is an important legume crop used in Pakistan however a systematic mapping of the chemical composition of mash bean seeds is lacking. Therefore seeds of four mash bean (Vigna mungo (L.) Hepper, family Leguminoseae) cultivars (NARC-Mash-1, NARC-Mash-2, NARC-Mash-3, NARC-Mash-97) commonly consumed in Pakistan have been analyzed for their chemical composition, antioxidant potential and biological activities like inhibition of formation of advanced glycation end products (AGE) activity and tyrosinase inhibition activity. RESULTS: The investigated cultivars varied in terms of biochemical composition to various...

Genetic characterization of pomegranate (Punica granatum L.) genotypes by AFLP markers Biol. Res.
Ercisli,Sezai; Kafkas,Ebru; Orhan,Emine; Kafkas,Salih; Dogan,Yildiz; Esitken,Ahmet.
The Coruh Valley, located in Northeastern Turkey, is one of the most important centers of diversity in pomegranate in Turkey. In this study, we attempted to characterize 19 promising pomegranate genotypes originating from the Coruh Valley in using fluorescent dye AFLP markers and capillary electrophoresis. Four AFLP primer combinations were used, generating a total of 297 fragments, 213 of which were polymorphic (73.0%). Resolving powers of the AFLP primers ranged from 0.700 to 1.018, with a total of 3.440, while polymorphism information contents ranged from 0.707 to 0.837 with an average of 0.764. UPGMA clustering of the genotypes showed two major groups. Most of the fruit characteristics of the genotypes within the same group were variable. Therefore,...

Influence of rootstocks on growth, yield, fruit quality and leaf mineral element contents of pear cv. 'Santa Maria' in semi-arid conditions Biol. Res.
Ikinci,Ali; Bolat,Ibrahim; Ercisli,Sezai; Kodad,Ossama.
BACKGROUND: Rootstocks play an essential role to determining orchard performance of fruit trees. Pyrus communisand Cydonia oblonga are widely used rootstocks for European pear cultivars. The lack of rootstocks adapted to different soil conditions and different grafted cultivars is widely acknowledged in pear culture. Cydonia rootstocks (clonal) and Pyrus rootstocks (seedling or clonal) have their advantages and disadvantages. In each case, site-specific environmental characteristics, specific cultivar response and production objectives must be considered before choosing the best rootstock. In this study, the influence of three Quince (BA 29, Quince A = MA, Quince C = MC) and a local European pear seedling rootstocks on the scion yield, some fruit quality...

Organic acids, sugars, vitamin C content and some pomological characteristics of eleven hawthorn species (Crataegus spp.) from Turkey Biol. Res.
Gundogdu,Muttalip; Ozrenk,Koray; Ercisli,Sezai; Kan,Tuncay; Kodad,Ossama; Hegedus,Attila.
BACKGROUND: The Hawthorn (Crateagus sp.) mostly occurs around the temperate region of the world with a high number of species, producing a fruit with numerous beneficial effects for human health. The aim of the study was to determine organic acid and sugar contents in the fruit of a number of hawthorn species grown in Erzincan province of Turkey. RESULTS: Citric acid was the predominant organic acid in all hawthorn species and C. pseudoheterophylla had the highest citric acid content (23.688 g/100 g). There were not statistically significant differences among hawthorn species (except C. atrosanguinea Pojark) in terms of fumaric acid content. C. pontica C.Koch had a higher content of vitamin C (9.418 mg/100 g) compared to other species. Fructose was the...

Kan,Tuncay; Gundogdu,Muttalip; Ercisli,Sezai; Muradoglu,Ferhad; Celik,Ferit; Gecer,Mustafa Kenan; Kodad,Ossama; Zia-Ul-Haq,Muhammad.
BACKGROUND: Turkey is the main apricot producer in the world and apricots have been produced under both dry and irrigated conditions in the country. In this study, phenolic compounds and vitamins in fruits of one wild (Zerdali) and three main apricot cultivars ('Cataloglu', 'Hacihaliloglu' and 'Kabaasi') grown in both dry and irrigated conditions in Malatya provinces in Turkey were investigated. RESULTS: The findings indicated that higher content of phenolic compounds and vitamins was found in apricot fruits grown in irrigated conditions. Among the cultivars, 'Cataloglu' had the highest rutin contents both in irrigated and dry farming conditions as 2855 µg in irrigated and 6952 µg per 100 g dried weight base in dry conditions and the highest chlorogenic...

Sugars, organic acids, and phenolic compounds of ancient grape cultivars (Vitis vinifera L.) from Igdir province of Eastern Turkey Biol. Res.
Eyduran,Sadiye Peral; Akin,Meleksen; Ercisli,Sezai; Eyduran,Ecevit; Maghradze,David.
BACKGROUND: The Eurasian grapevine (Vitis vinifera L.) is the most widely cultivated and economically important horticultural crop in the world. As a one of the origin area, Anatolia played an important role in the diversification and spread of the cultivated form V. vinifera ssp. vinifera cultivars and also the wild form V. vinifera ssp. sylvestris ecotypes. Although several biodiversity studies have been conducted with local cultivars in different regions of Anatolia, no information has been reported so far on the biochemical (organic acids, sugars, phenolic acids, vitamin C) and antioxidant diversity of local historical table V. vinifera cultivars grown in Igdir province. In this work, we studied these traits in nine local table grape cultivars viz....
