Other claims from this paper (6)

Intervention effect Partial defoliation in vegetative or reproductive phases reduced seed yield.
Association Yield reduction depended on crop stage and degree of defoliation.
Intervention effect Defoliation reduced total dry-matter production.
Intervention effect Defoliated plants had higher net assimilation rate from 40 to 60 days after sowing.
Mechanism Defoliation reduced the number of pods per plant, contributing to lower seed yield.
Mechanism Defoliation sometimes reduced seeds per pod and 100-seed weight, contributing to lower yield.

Other claims from this paper (12)

Intervention effect Under flooding, defoliation increased photosynthetic and transpiration rates.
Intervention effect Under flooding, defoliation increased leaf water content and diffusive conductance.
Observation The defoliation effect was particularly pronounced in tall upland varieties.
Intervention effect With restricted water, defoliation slowed soil moisture loss.
Intervention effect With restricted water, defoliated varieties maintained high photosynthesis longer.
Observation At 40 cbar soil moisture tension, photosynthesis and leaf conductance were similar with and without defoliation.
Intervention effect Under flooding, defoliation decreased yield components except tiller number in tall varieties.
Intervention effect Under flooding, defoliation decreased grain weight per plant in every variety.
Intervention effect Under drought, defoliation alleviated decreases in several yield components.
Intervention effect Under drought, defoliation lessened grain-weight loss except in the dwarf mutant.
Recommendation Authors concluded defoliation prevents drought damage in tall large-leaved varieties.
Mechanism Authors postulated that the dwarf mutant's short thick leaves explain its smaller photosynthetic decline under drought.
