Potassium borates, which are widely used in welding and metal refining industry, as a lubricating oil additive, cement additive, fiberglass additive and insulation compound, are one of the important groups of borate minerals. In this study the production of a potassium borate mineral via hydrothermal method is aimed. The potassium source of potassium nitrate (KNO3) was used along with a sodium ...

A greenhouse experiment was conducted to investigate the effects of different types of nutrients induced salinity on the growth, membrane permeability, nitrate reductase activity, proline content and macronutrient concentrations of tomato plants. The plants were subjected to six different treatments: 1 (control) containing basic solution, 2 basic solution+40mM of NaCl, 3 basic solution+40 mM of...

In an effort to improve and promote the propagation of Terminalia sericea, the effects of temperature, photoperiod and growth regulators on seed germination were investigated. Seeds were tested with different temperature regime (10, 15, 20, 25, 30, 35 and 40C) and in photoperiod (4/20, 8/16, 12/12, 16/8 light/dark hrs and 24 hours continuous dark). Pre-treatments with growth regulators were don...

Optimum concentrations of nitrogen and potassium on in vitro microtuberization of Agria, a popular variety of Potato, Solanum tuberosum L., were evaluated. The concentrations of 0, 0.5, 1, 1.5, and 2 folds of standard concentrations of NH4NO3 (1650 mgl) and KNO3 (1900 mgl) were used in Murashige and Skoog (MS) medium, and their effects were studied on cell number, cell sizes, and number of amid...

We determined: (a) the physiological consequences of overproduction of putrescine in transgenic poplar (Populus nigra x maximoviczii) cells expressing an ornithine decarboxylase transgene; and (b) effects of variation in nitrogen (N) concentration of the medium on cellular polyamine concentration in transgenic and non-transgenic cells. Cells grown in the presence of supplemental (to the normal ...

An alkaline protease producing bacterial strain Bacillus licheniformis (MTCC NO. 7053), which was obtained from IMTECH, Chandigarh used for protease production studies. Three significant variables effecting protease production like rice husk (variable 1); inoculum size (variable 2); KNO3 (variable 3) have been identified under preliminary optimization studies. These variables are selected for a...

This study aims to determine the effect of KNO3, H2SO4, and GA3 in breaking dormancy germination salak (Salacca zalacca) plants. In this using a non-factorial randomized block design with one factor, namely P0 (control), P1 (KNO3 60%), P2 70%), P3 80%), P4 (H2SO4 P5 P6 P7 (GA3 25 ppm), P8 50 P9 75 P10 60% P11 70% P12 80% P13 P14 P15 75). Parameters observed were germination, maximum growth pote...
