The Tetrazolium Chloride (TZ) test, often called the quick germination test, is a chemical test used to determine seed viability, and results are usually available within 24 to 48 hours The TZ test differs from a germination test in that the TZ test can give you an early and quick snapshot of seed viability but is not a replacement for the more comprehensive seed germination test.
Norman C. Deno (February 15, 1921 – September 22, 2017) was an American chemist and plant scientist.He was a professor of chemistry at Penn State University and is known as one of the foremost researchers in seed germination theory.
The Lurgi–Ruhrgas process is a hot recycled solids technology, which processes fine particles of coal or oil shale sized 0.25 to 0.5 inches (6.4 to 12.7 mm). As a heat carrier, it uses spent char or spent oil shale (oil shale ash), mixed with sand or other more durable materials.
Under a contract with the German company Lurgi and the Iranian company PIDEC, the construction process of the first phase of Zagros Petrochemical began in 2001 with an annual capacity of 1,650,000 tons of methanol, and was completed in 2006. The second phase of this company was completed in 2009.
The Lurgi AG German industrial group was a partner, and it was the Lurgi office in Tokyo. The Combined Intelligence Objectives Sub-committee of the United States and United Kingdom later investigated it. [1] At the beginning of 1942 the Japanese acquired all the low temperature carbonization patents of Lurgi for Japan, Manchuria, and of China ...
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...
Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. [3] In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its hard seed coat softened by frost and weathering action. By doing so the seed is undergoing a natural form of "cold ...
The STG+ process uses standard catalysts similar to those used in other gas to liquids technologies, specifically in methanol to gasoline processes. Methanol to gasoline processes favor molecular size- and shape-selective zeolite catalysts, [2] and the STG+ process also utilizes commercially available shape-selective catalysts, such as ZSM-5. [3]
