Other claims from this paper (8)

Intervention effect Chlorophyll content of the third leaf decreased faster under low humidity than under high humidity.
Intervention effect Rice plants grown under low humidity had lower water content than those under high humidity.
Association Decrease of water content in rice leaves was followed by decrease of chlorophyll content.
Intervention effect High humidity increased the leaf area of rice plants.
Intervention effect High humidity accelerated leaf emergence in rice plants.
Mechanism Products of photosynthesis in the third leaf were necessary for young leaf emergence.
Association More materials translocated from the third leaf were associated with faster senescence of that leaf.
Intervention effect High humidity delayed third-leaf senescence in rice, which the authors link to promoted growth.
