Other claims from this paper (10)
- Observation Olive pollen oil bodies had three enzyme activities on their surface.
- Observation Enzyme activity increased during germination and peaked after 3h.
- Intervention effect Removing extracellular sugars did not affect pollen performance.
- Intervention effect Removing extracellular sugars increased enzyme activity rates.
- Intervention effect Removing extracellular sugars sped oil body mobilization.
- Intervention effect Inhibitors hampered pollen germination and tube growth.
- Intervention effect Inhibitors caused oil bodies to accumulate in the germinative aperture.
- Mechanism Storage lipids were judged sufficient for olive pollen germination.
- Mechanism Extracellular sugars may modulate lipase and lipoxygenase function.
- Mechanism Phospholipase A may facilitate access to storage lipids.
