摘要：

A comparison was made between the Soxhlet analysis (SA) and homogenizer extraction method (HEM) in determining the rubber and resin content in the root, main stem, and branch tissues of 10 genotypes of guayule grown in Mexico. The analysis of variance indicated significant differences in percentage of rubber and resin between genotypes, and individually in the root, stem, and branch tissues, and also between two rubber extraction procedures. The average rubber in the root, stem, and branches as determined by the SA was 2.48, 4.14, and 4.66%, respectively; in the HEM, comparable figures were 2.62, 3.48, and 3.84%, respectively. The SA estimated 18.97% and 20.83% higher rubber content in the stem and branches tissues over HEM. The SA method yielded higher percentage values for rubber and resin contents when compared to the HEM. The HEM requires considerably less time to analyze the samples.
