In this study, the most suitable mantle part and host mussel species for pearl sac formation were determined. A total of 400 mussels, consisting of four different types (Unio terminalis, Potamida littoralis, Leguminaia wheatleyi and Anodonta pseudodopsis) were used. The average dorso-ventral lengths of the mussels were respectively; 7.89±0.25; 7.28±0.38; 10.68±0.27 and 11.14±0.34 cm. Mantle tissue slices in the size of 3×3 mm obtained from the pallial edge of mantle tissue were used as grafts. Two different mantle sections were identified for graft implantation, one being the mantle cavity and the other was incisions on the mantle tissue. At the end of the three-month pearl culture, the mantle cavity section was identified as the best graft implant site. U. terminalis was determined as the most successful species in terms of survival rate and pearl formation. P. littoralis was the second successful species and L. wheatleyi was the lowest among the species. This study is a guide for long-term pearl production on nacre thickness and quality which are considered important in pearl production.

Pulses in Pakistan is used in combination with cereals to balance the diet. Its area and production is decreasing for last many years. In the barren and partly arid regions, water shortage is the major component that restricts yield. Using of drought resistance plant is one of the best ways for good cultivation under drought condition. As the pulses have great nutritional and economical values and drought stress affect their morphological features. The legume yield is mostly cultured in rain fed region of the Punjab where they bear a slighter quantity of water situation resulting in low yield of bean. To overcome these problems it is necessary to get knowledge about the performance of different lines of different pulses crops under water stress conditions. That’s why in this paper the information about the previous literature has been discussed.

Antioxidants, usually contain phenolic groups, molecules may prevent the formation of free radicals or by blocking the radicals to prevent damage to the cell. Antioxidant molecules can be produced by the body or taken into the body through foods. Today, there are many different methods used to measure antioxidant capacity. In these methods, measurements are usually carried out by adding the tested substances into a solution containing free radicals. These methods can give different results depending on the characteristics of the reactant used. In this study, the reproducibility and consistency of five different antioxidant capacity methods (DPPH, ABTS, galvinoxil, phosphomolybdenum and FRAP) in commercially available and homemade turnip samples were tested. At the end of the study, antioxidant activities of the tested samples were evaluated. According to the evaluation of the antioxidant activities (from higher to lower) of these samples, the results of, DPPH, galvinoxyl, phosphomolybdenum and FRAP methods were very similar. However, ABTS method results showed difference compared to other method results. As a result of study, reproducibility and consistency of results of DPPH, galvinoxyl, phosphomolybdenum and FRAP methods were determined.
