Other claims from this paper (7)
- Observation Apple pollen tube growth was nearly linear for six hours.
- Observation Nicotiana alata pollen tube growth rate decreased after 10 to 15 hours.
- Observation The sucrose inversion rate rose until substrate exhaustion.
- Association Pollen tube growth slowed when sucrose concentration fell to 5%.
- Observation Apple pollen showed exogenous sucrose use after three hours.
- Observation Nicotiana pollen showed exogenous sucrose use after six to eight hours.
- Intervention effect Boron stimulated sucrose absorption in proportion to pollen tube growth.
