Other claims from this paper (10)
- Intervention effect One or two additional fruits did not affect first-fruit growth through 22 days after anthesis.
- Intervention effect Competition from fruits at the same node slightly decreased first-fruit weight at maturity.
- Observation In competition, pericarp growth was more affected than seed growth.
- Observation The larger pericarp response was particularly apparent when photon flux decreased 18–22 days after anthesis.
- Observation Dry matter allocation to later-formed fruits increased progressively over time across treatments.
- Intervention effect The number of competing fruits did not alter proportions of dry matter allocated among fruits.
- Intervention effect Reducing photon flux by more than two-thirds decreased fruit growth rates.
- Intervention effect Reducing photon flux had little effect on dry matter partitioning in most cases.
- Observation With all fruits retained, lower-node fruits tended to be less affected by decreased photon flux.
- Recommendation The authors suggest estimating allocation among fruits from fruit size and the developmental trend in relative growth rate without competition.
