T. O. Tayo The Journal of Agricultural Science 1986. doi:10.1017/s0021859600066764

Other claims from this paper (16)

Observation Only 30% of open flowers formed pods retained to maturity
Observation The terminal inflorescence produced 25% of the flowers on the plant
Observation Nodes 2 and 3 developed 50% of the retained pods
Observation Flower opening over the whole plant spanned an average of 12 days
Observation 90% of retained pods were formed from flowers opened within 4 days of anthesis
Observation Pod elongation was initially very rapid in pods that would be retained after fertilization
Observation Late pod growth was devoted almost entirely to seed filling
Observation Abscission development in Phaseolus pods proceeds at a slow growth rate
Observation Seed number per pod is determined later in pod growth
Intervention effect Flower or pod removal prolonged flowering
Intervention effect Flower or pod removal led to longer leaf retention
Intervention effect Flower or pod removal led to more branches on the main stem
Intervention effect Flower or pod removal lowered the number of mature pods
Association Greater severity of removal was associated with larger treatment effects
Intervention effect Plants compensated for fewer pods by producing more seeds per pod after flower or pod removal
Intervention effect Flower or pod removal shifted pod production away from nodes 2 and 3 to other areas of the plant
