Abstract:
The objective of this study was to determine the effects of genotype and environment on wax composition in jojoba seed, and thus be able to control it. Production of waxes with different compositions - and hence changed wax properties such as viscosity, boiling point, and thermal stability - may be of importance for future requirements of the jojoba industry. Wax composition of 23 female clones was determined for two growing seasons. The ratio of FA elongated to the sum of those reduced and esterified differed among genotypes, resulting in differences in the percentage of wax esters longer than 40 or 42 carbons. The clones 'Yarden', 'Gvati', 'Hazerim', 'BGU', and 'Negev' had higher percentages of long-chain wax moieties than the clones '879-154', 'MS 55-4', and 'Forti'. The contribution of the male genotype to wax composition was tested by pollinating bagged female flowers of four female clones with pollen from three male plants. Both male and female genotypes additively influenced the composition of the wax esters. Wax composition varied between growing seasons and locations, but differences between genotypes were consistent. Salinity of the irrigation water did affect wax composition in some clones. Under high salinity, the salt-sensitive clone '64' produced a smaller percentage of long-chain wax esters, whereas in clone 'Q-106' wax composition did not change. In clone '874-154' the chain lenghts of the wax moieties in the seeds increased under medium salinity. We conclude that jojoba wax composition is influenced by both female and male genotypes and by environmental factors such as climate and salinity.
