The choice of a good random seed is crucial in the field of computer security . When a secret encryption key cryptography key is pseudorandom ly key generation generated , having the seed will allow one to obtain the key. If the same random seed is deliberately shared, it becomes a secret key , so two or more systems using matching pseudorandom number algorithms and matching seeds can generate matching sequences of non repeating numbers which can be used to synchronize remote systems, such as GPS satellites and receivers.

In agriculture and horticulture , a seed treatment or seed dressing is a chemical, typically antimicrobial or fungidal, with which seeds are treated or dressed prior to planting. Less frequently insecticides are added. Seed treatments can be an environmentally more friendly way of using pesticides as the amounts used can be very small. It is usual to add colour to make treated seed less attractive to birds if spilt and easier to see and clean up in the case of an accidental spillage. One seed treatment, Imidacloprid , from the Neonicotinoid family of insecticides , is controversial and was banned in France for use on maize, due to that government s belief that the chemical was implicated in recent Pollinator decline dramatic drops in bee counts , and possibly in the so called Colony Collapse Disorder . Dust from treated seed is known to have caused at least some problems particularly from crops such as maize drilled during the main honey flows. Improvements to pneumatic drills to reduce dust release, and improvements to seed treatment compounds to prevent the compound breaking up into dust have been introduced in Europe led by Germany and Holland from 2009 to 2012. Information on seed treatments including the information above can be seen on the registration authority databases. http www.eppo.org PPPRODUCTS information information ppp.htm Seed coating is a thicker form of covering of seed and may contain fertiliser, growth promoters and or seed treatment as well as an inert carrier and a polymer outer shell.

These trees serve as both the gene source for the new crop of regeneration and as a source of timber during future cuttings. Because of its importance, a seed tree should be carefully chosen based upon both economic and biological factors. Selected seed trees should be the desired species, phenotype phenotypically superior, prolific in seeding and flowering, sturdy and healthy, free of damage, and of good growth form. After the site has been successfully regenerated, seed trees may be commercially harvested or the trees may be retained for visual enhancement and as backup against catastrophic losses of regeneration due to agents such as fire or drought. The presence of seed trees distinguishes the seed tree method from clearcutting . Many people consider the seed tree method more aesthetically pleasing than clearcutting because some mature trees are retained on the site for at least until regeneration becomes well established.

Unreferenced date December 2009 In agriculture and gardening , hybrid seed is seed produced by pollination cross pollinated plant s. In hybrid seed production, the crosses are specific and controlled. The advantage of growing hybrid seed compared to inbred lines comes from heterosis . To produce hybrid seed, elite inbred varieties with well documented and consistent phenotypes such as yield are crossed and the resulting hybrid seed is collected. Another factor that is important in hybrid seed production is the combining ability of the parent plants. Although two elite inbred parent plant varieties may produce the highest yields of their crop, it does not necessarily mean that crossing these inbreds will result in the highest yielding hybrid. Combining ability is the term used to describe the level of heterosis that the parents will generate in the resultant seed. Higher combining ability between the parents results in increased performance in the resulting hybrid seed. Hybrids are bred to improve the characteristics of the resulting plants, such as better crop yield yield , greater uniformity, improved color , disease resistance, and so forth. Today, hybrid seed production is predominant in agriculture and home gardening, and is one of the main contributing factors to the dramatic rise in agricultural output during the last half of the 20th century. In the US, the commercial market was launched in the 1920s, with the first hybrid maize . All of the hybrid seeds planted by the farmer will be the same hybrid, which causes the first generation of seed from the hybrids planted to be inbred. This is why hybrid seed is generally not saved from subsequent generations and is purchased for each planting. Hybrid seeds are much dearer than normal seeds, due to the technology, time and effort put in to produce them.
