Abstract
Fresh pollen of jojoba attained the highest pollen viability at the
beginning of the flowering season, where pollen fertility percentages for all
the tested male parents exceeded 90%. Pollen stored at 4°C showed a clear
significant decline in viability percentages following the long-term storage, i.e.
the longer the storage period, the lower the viability obtained.
The morphological characteristics of pollen grains of four selected jojoba
male parents were investigated with respect to the main characteristics of pollen
grains. The polar axis length (P) ranged from 32.34 to 33.32 urn, the equatorial
diameter width (E) ranged from 24.54 to 27.01 urn, while the ratio PIE ranged from
1.22 to 1.34. Pollen characteristics of all parents in equatorial view is spherical,
tricolpate. Exine sculpturing tends to be scarbate. Furrows (colpi) are long and wide.
