Rubber and resin contents of native guayule germplasm of Mexico

Industrial Crops and Products, 1997
Abstract Plant germplasm obtained from the origin of the genetic material can be useful for varietal improvement. For guayule (Parthenium argentatum Gray.) germplasm, 343 accessions were collected from 53 locations in 20 municipalities within five provinces (Coahuila, Durango, Nuevo Leon, San Luis Potosi and Zacatecas) in Mexico.

Effect of Resin Components on the Reversion Process of Sulfur-Vulcanized Guayule Rubber

Rubber Chemistry and Technology, 1986
Abstract An effort to characterize the reversion process of guayule rubber when naturally-occurring guayule resin components are present has shown that these components act as a reversion-retarding material. The amount of reversion resistance varies as a function of temperature, concentration, and type of fatty acid.

Overexpression of tocopherol biosynthesis genes in guayule (Parthenium argentatum) reduces rubber, resin and argentatins content in stem and leaf tissues.

Phytochemistry
Natural rubber produced in stems of the guayule plant (Parthenium argentatum) is susceptible to post-harvest degradation from microbial or thermo-oxidative processes, especially once stems are chipped.

Heritability of height, width, resin, rubber, and latex in guayule (Parthenium argentatum)

Industrial Crops and Products, 2001
Abstract Plant breeding in guayule, a rubber and latex producing plant, has not been as effective as predicted or desired. A surprisingly large amount of variability has been reported in this apomictic crop for traits such as plant height, width, resin, rubber, and latex contents.

The degradation of guayule rubber and the effect of resin components on degradation at high temperature

Journal of Applied Polymer Science, 1987
Degradation of pure guayule rubber and rubber in the presence of stearic, oleic, linoleic, and linolenic acid, has been studied at high temperatures (from 150°C to 600°C) using thermogravimetric analysis (TGA). On-line mass spectrometric analysis of the products of decomposition has also been done to understand the mechanism of degradation ...

Analysis of Rubber, Resin, and Moisture Content of Guayule by Near Infrared Reflectance Spectroscopy

Rubber Chemistry and Technology, 1985
Abstract Although the overall error associated with the NIR analysis of guayule may be slightly higher than that of some other methods, the trade-off between the increased error and the very rapid aquistion of data by NIR is quite positive.

Environmental and chemical effects on growth, resin and rubber production in guayule tissue cultures

Phytochemistry, 1991
Abstract Several environmental and chemical factors affected rubber accumulation in guayule (Parthenium argentatum) tissue cultures. Light increased rubber yields in callus and shoot cultures by 50 and 450% respectively. The Mr of rubber in light-grown callus increased by 60%.
