Other claims from this paper (8)
- Intervention effect Pod removal increased the numbers of flowers, ovules and viable seeds compared with untreated bean plants.
- Intervention effect Pod removal increased the total weight of pods compared with untreated bean plants.
- Intervention effect The proportion of ovules giving rise to viable seeds, aborted seeds and undeveloped ovules was the same with and without pod removal.
- Observation Approximately 50% of ovules of marketable pods yielded viable seeds in all plants.
- Observation The 12 cohorts of flowers contributed markedly different amounts to bean plant yield.
- Association Early and later flower cohorts contributed much less marketable pod dry weight than middle cohorts.
- Observation Peak productivity was obtained from the middle phase of flowering in bean plants.
- Mechanism The lower pod yield of later cohorts is interpreted as resulting from competition for limited resources between maturing pods and new flowers.
