Cadmium (Cd) is one of the toxic heavy metals not essential for the growth and development of plants and other organisms. Brassica rapa accumulates several heavy metals in its leaves and is reportedly suitable for phytoremediation. In this study, Cd uptake and accumulation in the leaves of B. rapa exposed to different cadmium levels (0, 5, 10, 20, 50, 100 μM CdSO4) were analyzed, as well as the effect of Cd stress on HMA2 and HMA4 genes expression were investigated. The qRT-PCR results showed that HMA2 and HMA4 play a vital role in cadmium uptake and translocation in B. rapa at low Cd levels (5-20 μM). However, exposure to high Cd levels (50 and 100 μM) significantly reduced the growth and biomass of B. rapa. Furthermore, high levels of Cd inhibit the expression of HMA2 and HMA4 genes in B. rapa. Our data show a multigenetic (co-acting of many transporter gene clusters) response in the signaling pathway associated with Cd accumulation and tolerance mechanism in B. rapa.

This study was carried out to determine the root development of black mulberry hardwood cuttings kept in light and dark conditions. The experiment was carried out in the polyethylene greenhouse of Tokat Gaziosmanpaşa University Research and Application Center, in 2021. As material, hardwood cuttings prepared from one-year-old branches of black mulberry trees were used. The cuttings were divided into 3 different groups and planted in rooting beds containing perlite with bottom heating (22±2 °C). First group of cuttings were planted into beds as soon as taken from tree (control), the second group of cuttings were plantend after the cuttings were kept under daylight conditions for 5 days (in the open) and third group cuttings were planted after the cuttings were kept in the dark conditions (in the dark) for 5 days in both conditions soaked in water. All cuttings were dipped in 6000 ppm IBA (indole-3-butyric acid) hormone for 5 seconds just before planting. The experiment is with 3 replications and there are 15 cuttings in each replication. After keeping 90 days in the rooting environment, the cuttings were removed; root number (root/stem), root length (cm), root diameter (mm), decay rate (%), rooting rate (%) and callus formation rate (%) parameters were investigated. As a result of the study, there was no statistical difference between the different conditions in the investigated parameters. The data obtained varied between the following values; rooting rate between 68.89% - 93.33%, decay rate between 24.4% - 55.5%, callus formation rate between 68.8% - 88.8%, number of roots 8.8 - 13.5 root/stem, root length 6.5 - 7.4 cm and root diameter between 1.02 - 1.16 mm.

Cumilla Sadar Dakshin region is highly diverse in respect to land types, topography, agro-ecology, land-use pattern, cropping systems and crop variability & variety. Agricultural development of the region largely depends on the reliable and comprehensive statistics of the existing cropping cultivation and its related system adopted by the farmers. To investigate the homestead vegetable production and its impact on family nutrition, food security, income generation as well as involvement of female members a survey study was conducted at Cumilla Sadar Dakshin during 2019. A total of 150 selected homesteads were surveyed for this purpose through developed questionnaire and focus group discussion. Both primary and secondary data has been collected from different sources to fulfill the objectives of the study. The results of this study indicated that the farmer’s age, marital status, education level, farm size, source of income, women participation etc. Farmer’s knowledge and farming experiences, perception and attitude differs on different demographic conditions like: age, sex, education, farm size, training which significantly influence the adoption of modern technologies provided by different organizations. The results also showed that women contribution in homestead vegetable production is high in medium farmer’s category 41.67% and low in small farmers 36.36% respectively. The highest number of total vegetables was produced by the medium farmer (63,732 kg/year) followed by small (39,445 kg/year) and marginal farmer (25,514 kg/year). This study provides some recommendation which might impacts on betterment of farmers’ occupational and socio-economic condition by establishing proper policy and legislation both in local and national level administration as well as agricultural extension.

In this research, fresh green peppers were dried in a kitchen microwave oven at 600W, 700W and 800W. The drying curves of the study were compared with 5 different thin layer drying models in the literature. The changes in the moisture values of the samples against time were expressed graphically. R2, χ2 and RMSE values were used to determine the most suitable model for dried green peppers. Color values of fresh and dried peppers were determined. It was found that the L* and b* values of the dried peppers were lower, and the a* value was higher than the fresh green peppers. In addition, the rehydration rate of dried peppers was calculated. It was determined that the rehydration ability of the peppers decreased as the applied microwave power increased. For this reason, it was found that the peppers with the highest rehydration rate were those dried with 600W. Also, it was found that the most suitable model for all microwave powers among the five drying models was the Logarithmic drying model. It was calculated that the R2 values of the drying models ranged between 0.830-0.999, χ2 values between 0.0001- 0.4684 and RMSE values between 0.0014-0.6121. It was determined that the highest R2 (0.997-0.999), the lowest χ2 (0.0001-0.0002) values, and the lowest RMSE (0.0014-0.0035) values for all microwave powers belong to the Logarithmic drying model.

The main purpose of this study is to compare the perceived stress level of university students in terms of body-mass index categories and gender. 235 university students (183 female, 53 male) between the ages of 18-40 participated in the study. Participants were selected from six different departments of six universities by convenient sampling. In the study, a personal information form asking about university, department, age, disease status, drug use, weight, height and gender, and a perceived stress scale were used as data collection tools. While body mass index (BMI) categories and gender were determined as independent variables in the study, perceived stress level was determined as dependent variable and the data were analysed with a one-way ANOVA test. The findings revealed that there was no statistically significant difference in the perceived stress levels of the participants in terms of gender and body mass index categories. However, for one factor of the stress scale (readiness to cope with stress), participants in the normal body mass index range reported significantly less stress than participants in the obese body mass index range. The findings will be discussed in the light of the literature.
