Abstract
Guayule produces both ethanol and water-soluble fructans. The water-soluble fructans act as a ‘true’ carbohydrate reserve. When the demand for carbon increases greatly, the water-soluble fructans are readily depolymerized. The ethanol-soluble fructans are quickly metabolized providing a readily accessible carbohydrate source. They are extensively depolymerized at budbreak and flowering. The polymerization of water-soluble fructans occurs in November/December and during the winter months. This is indicative of the availability of excess fructose at these times. The mature stem and roots appear to be primary sites of fructan storage, with the supply in the roots being the least accessible. Starch, which occurs primarily in the leaves, is apparently involved in sucrose storage. Guayule produseer beide etanol- en wateroplosbare fruktane. Die wateroplosbare fruktane dien as ‘ware’ koolhidraatreserwes. Wanneer die behoefte aan koolstof drasties toeneem word die wateroplosbare fruktane geredelik gedepolimeriseer. Die etanoloplosbare fruktane word vinnig gemetaboliseer en dien as ’n geredelik beskikbare koolhidraatbron. Hulle word grootliks gedepolimeriseer gedurende knopgroei en blomvorming. Die polimerisering van wateroplosbare fruktane geskied in November/Desember en gedurende die wintermaande. Dit dui op die beskikbaarheid van ’n oormaat fruktose gedurende hierdie tye. Die volwasse stingel en wortels skyn die hoofstoorplekke van fruktaan te wees. Die voorraad in die wortels skyn die mins toeganklike te wees vir gebruik. Stysel, wat hoofsaaklik in die blare voorkom, blyk betrokke te wees by die stoor van sukrose.
