Potassium nitrate and sodium in mixing proportion of KNO3–NaNO3 40-60 wt% (also called solar salt) has been successfully used for over a decade as heat storage medium concentrated power parabolic-trough collector plants at temperatures up to 400 °C. At 560 °C, reached state-of-the-art tower systems, corrosion metallic components contact with salt can become an issue caused leaks plant shut-down...

germination is a critical stage in the life cycle of plants and often controls population dynamics, with major practical implications. salsola arbusculiformis is one of the most important plants used to prevent soil erosion and a good fodder resource for sheep and goat in the rangelands of iran. however, the species seems to have low seed germination, so the purpose of this study was to investi...

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...

Nitrate reductase (NR) activity, induced by germination in KNO3 showed a strong rhythmicity during the early stages of germination of wheat embryos. Peaks of activity occurred approximateiy every 12 h. Tbere was no relationship hetween the amounts of nitrate in tbe embryos and enzyme activity. Tbe fluctuations in enzyme activity did not appear to be due to reversible inactivation of the enzyme....

in order to investigate the effects of supplementary calcium chloride and potassium nitrate on plant growth of ammi (carum copticum l.) in different salinity levels and nutrient solutions (ns), an experiment based on randomized complete block design (rcbd) with factorial arrangement was conducted under greenhouse condition in the faculty of agriculture, vali-e-asr university of rafsanjan, durin...

welsh onion (allium fistulosum l.) is one of the important vegetable crops in china. however, the seeds of this crop are short-lived and their vitality tends to be easily lost in the course of storage. the present study was conducted to elucidate the effects of welsh onion seed priming with potassium nitrate (kno3) on seed vigor and on other such related mechanisms during twelve months of stora...

The present study examined the effects of different nitrogen (NH4NO3) and potassium (KNO3) fertilization levels in combination with a nitrogen-fixing, plant growth-promoting rhizobacteria (PGPR) inoculation on carbohydrate (CHO), amino acid content, nutrient concentrations (N, P, K) spears root system asparagus plants. No significant differences were indicated between treatments regarding N, K ...

Nitrate is one of the major sources of nitrogen for the growth of plants. It is taken up by plant roots and transported to the leaves where it is reduced to nitrite in the. The main objective of this research was to investigate stimulatory effects of sodium nitrate, potassium nitrate, ammonia and urea on the production/generation of the nitrate reductase mRNA in Triticum aestivum plants. The pl...

Myristica fragrans Houtt. is a spice plant that used as in the kitchen, food preservatives, beverages, perfumes, cosmetics and soaps. The large use of nutmeg plants results high industrial demand for but availability minimal because generative propagation using seeds still constrained structure seed coat hard so germination takes up to 8 weeks. Dormancy breaking can be done with chemical compou...

Reduction of nitrate takes place when the stored energy in the form of colour centres is released during dissolution of g-irradiated crystalline potassium fluoride in aqueous potassium nitrate solution. Various parameters like dose, amount and storage time of irradiated potassium fluoride which control the yield of nitrite have been studied. Similarly, the effect of concentration of potassium n...
