Effects of different media on the transplantation of Huperzia serrata (Thunb.) Trev.

Wild Huperzia serrata was transplanted to moss, sand, corrosion soil, experimental garden soil, vermiculite mixed with perlite (1:1), and corrosion soil mixed with garden soil (1:1). The highest survival rate (90.0%) was observed in the moss medium, the second highest rate (53.3%) was detected in corrosion soil medium, and the lowest rate was found in garden soil medium. The physiological indices...

Contents of oxalic acid, nitrate and reduced nitrogen in different parts of beetroot (Beta vulgaris var. conditiva Alef.) at different rates of nitrogen fertilization

Beetroot has many positive effects on human health but can also accumulate considerable amounts of harmful nitrate and oxalate. A two-year open field trial was carried out to evaluate the influence of nitrogen fertilization on the content of different N compounds and oxalate in beetroot. Three nitrogen rates were applied: 0, 75 and 150 kg of N ha-1. Dry matter, oxalate, nitrate N and reduced N were determined in storage...

Marketing price transmission analysis in the Iranian rice market

The goal of this paper is to test whether changes in the marketing margin between the farm and the retail prices can result in an asymmetric relationship between the on farm and the retail prices in the rice market of Iran. By separating the transaction cost variation into two regimes, this paper utilizes a two-type TVECM with the error correction. The empirical results show that when the marketing margin is lower than...

Analysis of protein by colorimetric and computer color based intensity measurement method with anatomical sections of gram (Cicer arietinum) stem at three stages of growth

This research work is based on the establishment of new and easy techniques for the analysis of total proteins from anatomical sections. The proteins were measured from three different growth stages of stems of gram (Cicer arietinum). Firstly, protein was measured by colorimetric method and then analyzed from the cross sections of the same part of plant, sections were then stained with two different dyes and after that...

Effect of different carbon sources on the accumulation of carbohydrate, nutrient absorption and the survival rate of Chinese ash (Fraxinus mandshurica) explants in vitro

In this study, we analyzed the effect of different carbon sources on: (i) carbohydrate and nutrient absorption in Chinese Ash (Fraxinus mandshurica) explants in vitro, and (ii) explant survival rate during ex vitroacclimatization. The explants were cultured under one of five conditions: (1) in a solid medium supplemented with 30 g l-1 sucrose (SM); (2) in a modified temporary...

Genetic studies on divergence and phenotypic characterization of indigenous and exotic indica germplasm lines in rice (Oryza sativa L.)

Rice (Oryza sativa L.) is one of the most important staple cereal food crop and a source of calories for more than half of the world’s population. Genetic diversity in the world rice germplasm is larger but only small collections have been used in breeding programs since a high genetic similarity is found within germplasms around the world. An investigation was carried out at Tamil Nadu Rice Research...
