Other claims from this paper (7)
- Intervention effect Raffinose was the best tested substrate for apple pollen-tube growth and respiration.
- Intervention effect Apple pollen-tube growth in sucrose was retarded after about six hours.
- Intervention effect No corresponding decrease occurred in apple pollen tubes in raffinose even after 10 to 20 hours.
- Intervention effect Apple pollen tubes inverted raffinose more slowly than sucrose.
- Mechanism Slower inversion is proposed to cause raffinose's long-term effect on apple pollen tubes.
- Intervention effect Apple pollen did not germinate in turanose solution.
- Mechanism The authors propose β-D-fructofuranose as the primary factor in sucrose and raffinose effects on apple pollen-tube growth.
