The global economy relies on natural rubber (NR) for transportation of goods and people via tires and automobile components. Rubber is also critical to a plethora of industrial and medical products including gloves, condoms, and catheters. New and emerging uses of NR include space exploration, innovative medical procedures and specialized electronics. Despite the fact that thousands of plants produce NR, the tropical rubber tree, Hevea brasiliensis, remains the sole commercial source of NR. H. brasiliensis is unable to keep up with projected increases in NR demand due to many factors but especially small growing regions that are unable to expand without illegal deforestation of rainforests and high susceptibility of rubber trees to diseases. Concerns for the NR supply have sparked interest in alternative NR-producing plants with potential to supplement or replace the Hevea supply chain. There are three species besides Hevea which have been commercialized and had rubber extracted in bulk quantities during World War II: 1) Parthenium argentatum Gray (guayule), 2) Scorzonera tau-saghyz Lipsch. & G.G.Bosse (STS, mountain gum), and 3) Taraxacum kok-saghyz Rodin (TK, rubber dandelion). The work of this dissertation focuses on the potential of TK as an alternative rubber-producing crop. Of the three alternative rubber plants which have been successfully commercialized in the past, it is the only one capable of hydroponic growth, opening the door to unique NR production systems such as indoor and vertical farms. TK is also well suited to outdoor field production in temperate regions such as northern United States, much of Europe and a similar temperate region south of the equator, meaning it has a much larger habitable zone than Hevea. Additionally, at 6 months old TK has rubber of commercial quality, whilst Hevea is not tappable until 7 years old, making it a much more adaptable species for scaling up production in the event of a rubber crisis. The focus of this work was to assess the potential seed, root, rosette and rubber yields of TK in greenhouse and hydroponic production systems. Key questions regarding storage techniques of harvested roots for preservation of rubber and latex were answered as well. Finally, improved methods for extracting latex from TK roots, as well as TK latex evaluation and product testing were included. The product testing stage of this research resulted in production of the world's first TK latex glove.
