Şebnem Kuşvuran | Sevinç Uslu Kıran | Özlem Altuntaş
Drought stress is one of the most serious abiotic stresses that cause a reduction in plant growth, development and yield in the world. The aim of this study is to reveal the morphological, physiological and biochemical responses of the Demre pepper variety and nine different pepper genotypes against drought stress. Pepper seeds were planted into trays containing peat: perlite (2: 1) mixture. Then, seedlings having two leaves were transferred to plastic pots containing mixture of peat:perlite (2:1) mixture. Drought stress application was started when the plants have four leaves. The control plants were irrigated with nutrition solution. Genotypes were classified according to the severity of leaf damage symptoms by using 0-5 scale. In addition, shoot fresh and dry weight, plant height, stem diameter, leaf number, leaf area, relative water content (RWC), membrane injury index (MII), potassium (K) and calcium (Ca) concentration of shoot, malondialdehyde content (MDA), total chlorophyll and carotenoid, total flavonoid and phenolic content, anitoxidative enzyme activities (superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), ascorbate peroxidase (APX)) were also determined. As a result of the study, it was determined that drought had negative effect in terms of morphological and physiological parameters, and this effect revealed differences among genotypes. While drought stress increased MDA and antioxidative enzyme activity, BIB-6 and BIB-8 genotypes were found to be the most tolerant genotypes among the genotypes examined.

The aim of this study was to determine effects of different dietary rosemary essential oil levels on growth performance, carcass traits and haematological values of breeder chukar partridge. Eighty (60 females and 20 males), 32-week-old breeder chukar partridge were randomly divided in five treatments, with four replicate pens with 4 birds each. Five experimental diets were formulated according to rosemary essential oil inclusion rates 0 mg/kg, 24 mg/kg, 48 mg/kg, 72 mg/kg and 96 mg/kg, respectively. The experiment lasted for 8 weeks. The chukar partridges had free access to ad libitum feed and water. At the end of the trial, 1 male and 1 female partridge were slaughtered for blood analysis. The obtained results showed that there was no significant difference in feed intake, body weight gain between the control and treatment groups. Dietary rosemary essential oil supplementation did not affect blood serum glucose, urea, triglyceride, total cholesterol, HDL-C and LDL-C levels in breeder Chukar partridges. It could be concluded that supplementing rosemary essential oil into Chukar partridges diet show no negative effect on growth performance.

Cooking takes the largest percentage of energy consumption and most households still depend on wood fuel energy, which contributes significantly to global warming. However, a major consideration for market infiltration of a green energy product is the willingness of consumers to pay for it. The study examined the determinants of willingness to pay for biofuel among small-scale food sellers in Ibadan metropolis. Primary data were collected from one hundred and fifty-five small-scale food sellers in Ibadan metropolis using a multi-stage sampling procedure. Data were analysed using descriptive statistics and probit regression. The majority of the food sellers were female (91.0%) with less than five household members (65.8%) and had tertiary education (40.0%). Most of them were not aware of biofuel (82.6%) but were willing to substitute firewood for biofuel (78.1%). The probability of willingness to pay for biofuel was increased by household size, being a female but reduced by bid at the unit price of ₦500 per litre. However, it was reduced by household size and education at ₦600 per litre. Based on the findings of this study, the entrepreneurs should take advantage of the emerging biofuel market by creating awareness of green energy and its benefits among the citizenry while government should support its production so that it can be sold at affordable price.
