| Abstract: | The effect of micronutrient supply on the growth and seed production of guayule (Parthenium argentatum Gray) was investigated. A deficiency of boron, but no other trace element, significantly reduced the growth, seed production and the percentage of seeds that germinated. The optimum concentration of B for seed production was between 20 and 100 μM. Results indicate that guayule may benefit from B fertilisation. |
