Other claims from this paper (12)

Observation Low water potential decreased silk water potential.
Observation Low water potential decreased seed set.
Observation Low water potential left pollen water potential, appearance and viability unaffected.
Observation High temperature decreased pollen water potential by 2 megapascal.
Observation High temperature damaged shed pollen.

Observation High temperature reduced pollen shed in two hybrids.
Observation Prolificacy did not increase silk solute accumulation.
Observation Prolificacy improved seed production at low water potential.
Association The hybrid retaining relatively high silk turgor lost the most seed production under water deficit.
Observation Silk solute regulation capability did not vary among hybrids differing in prolificacy.
Observation The prolific hybrid had the least water-deficit effect on pistillate seed production.

Intervention effect Light 2 raised two fluorescence ratios within minutes.
Observation Mesophyll chloroplasts established state 2 more rapidly than guard cell chloroplasts.
Intervention effect Higher light 2 intensity shortened the time for guard cell chloroplasts to attain the new ratio.
Intervention effect DCMU-treated mesophyll and epidermal tissues did not transition to state 2.
Intervention effect NaF-treated tissues reached state 2 but could not return to state 1.
