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.
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 ...
The soaking increases the water content in the seeds and brings them out of quiescence. After draining and then rinsing seeds at regular intervals, the seeds then germinate, or sprout. For home sprouting, the seeds are soaked (big seeds) or moistened (small), then left at room temperature (13 to 21 °C or 55 to 70 °F) in a sprouting vessel.
Cultivation of cannabis is the production of cannabis infructescences ("buds" or "leaves"). Cultivation techniques for other purposes (such as hemp production) differ.. In the United States, all cannabis products in a regulated market must be grown in the state where they are sold because federal law continues to ban interstate cannabis sales.
The International Seed Testing Association (ISTA) is an independent, non-profit organization founded during the 4th International Seed Testing Congress in 1924. Its members work to promote uniform methods of evaluating seeds being sold internationally to facilitate the international trading of seeds and to contribute to global food security.
Thiram was therefore developed as a seed treatment in the 1940s to extend the spectrum of diseases that could be controlled. [6] In 1949 ICI commercialised a seed treatment with trade name Mergamma A, containing 1% mercury and 20% lindane, an early example of a product designed to protect the seed from both fungal and insect attack.

Hemp milk, or hemp seed milk, is a plant milk made from hemp seeds that are soaked and ground in water. [1] The result resembles milk in colour, texture, and flavour. Hemp is conducive to being organically grown and labelled. Plain hemp milk may be additionally sweetened or flavoured.
Apomixis (self-cloning), where seeds are produced asexually and the new plant is genetically identical to its parent; The mode of reproduction of a crop determines its genetic composition, which, in turn, is the deciding factor to develop suitable breeding and selection methods. Knowledge of mode of reproduction is also essential for its ...
