Linoleic, oleic, palmitic stearic acids the most prominent in all genotypes. abundant studied seeds, which belong different genotypes, potassium (2704.75–1033.63 ppm)...

Abstract Melatonin, an important phytochemical, encourages plants to redirect growth in response environmental stresses. The study aims investigate the changes morphological, physiological, biochemical, and molecular properties of spinach subjected exogenous application melatonin (MEL) at different doses under water stress. following four irrigation levels were applied: I 100 (complete irrigation), 80 (20% deficit), 60 (40% 40 (60% deficit). MEL was applied through a spray on leaves three...

Cucurbita pepo L., an important member of the Cucurbitaceae family, has a wide genetic diversity in terms fruit and plant characteristics. The objective this study was to select genotypes with desirable morphological characteristics establish core collection. Selected 200 were identified detail using 22 characters. Principal component analysis (PCA) cluster used determine relationships among these genotypes. As result PCA, eight PC axes explained 63.8% cumulation variation, while according...

Drought adversely affects crop production in areas with water shortages. In such areas, various methods need to be implemented alleviate the effect of stress on plants. Nitric oxide (NO) is an important plant growth regulator that physiological processes. this study, we determined ways increase water-stress tolerance lettuce by applying exogenous sodium nitroprusside (SNP, a donor NO). total, 12 treatments were administered, including three SNP doses (0, 50, and 100 µM) four levels...

This study was carried out to determine the effects of different Arbuscular Mycorrhizal Fungi (AMF) species on growth and nutrient contents pepper seedlings (cv. Demre) grown under moderate salt stress. Two mychorrhizas (Glomus intraradices Gigaspora margarita) were tested a growing media containing stress (75 ppm NaCl). The replicated four times with 8 plants in each replicate. At end study, some nutrients such as P, K, Ca, Na plant parameters shoot height, stem diameter, root length, dry...

The effects of potassium and humic acid (HA) on emergence, growth nutrient contents okra (Abelmoschus esculentus L cv. Sultani) seedlings in saline soil conditions were evaluated. Different levels (0, 500, 1000 1500 mg kg-1) 75, 150 300 applied growing media treated with 50 NaCl kg-1 before seed sowing. experiment was designed as randomized completely factorial block each parcel had ten pots without drainage. Two seeds sown pot having cc volumes media. thinned to one after emergence....

This study was conducted to investigate the effect of different irrigation and nitrogen levels on lettuce yield characteristics in greenhouse condition from December 2006 March 2007. Irrigation 100% total class A pan (S1), 80% (S2), 60% (S3) 0 kg ha-1 (N1), 100 (N2), 200 (N3), 300 (N4) were applied by drip system. did not show any significant head weight, marketable number leaves, height plants, circle, root length, extent except core length soluble solid, TSS. The highest weight found as...

Abstract TMV ( Tobacco mosaic virus ) and TSWV Tomato spotted wilt are the most common diseases that causes loss of productivity in pepper cultivation. The effective method fight against viral is use resistant cultivars. This study was conducted to determine similarities differences 120 Capia lines S2 stage, consisted local populations, standard hybrid cultivars, terms morphological variation resistance levels TMV. As a result molecular analysis, genotypes 34, 35, 36, 46, 47, 48, 84, 85 were...

Although the majority of carrots grown in Turkey and around world are orange, production anthocyanin-containing purple has recently increased due to extraction anthocyanin from these for use as a natural food colorant. Purple carrot this purpose is concentrated Ereğli District Konya Province, open-pollinated local cultivars or landraces have been used production. Genetic variation within populations region interest plant breeders worldwide development new cultivars. Therefore, study, genetic...

AbstractGlobal warming and the subsequent climate change increase severity frequency of floods day by day. Therefore, there is a need to develop new strategies prevent negative effects flooding stress determine changes that may occur in plant under extreme water stress. Thus, this study, agronomic, physiological, biochemical properties lettuce plants exposed greenhouse conditions were analyzed. In two different irrigation regimes, including full (I100) (I150) three nitrogen doses,...

-1 ) of inoculum was placed in the seedling growth medium before seeds were sown. At end study, some nutrients such as N, P, K, Ca, Mg, Fe, Cu, Mn, and Zn plant parameters shoot height, stem diameter, root length, leaf number, area, dry fresh weights shoots roots investigated.
