Title

Effects of water stress on glycolate metabolism in the leaves of rice seedlings (Oryza sativa)

Arun Goyal Physiologia Plantarum 1987. doi:10.1111/j.1399-3054.1987.tb04289.x

Other claims from this paper (4)

Intervention effect Water stress reduced glycolate content and catalase activity in rice.
Intervention effect Water stress increased glycolate oxidase activity, hydrogen peroxide and glyoxylate contents in rice leaves.
Intervention effect With increasing water stress duration, the label proportion increased in glycolate, glycine and serine.
Association The drought-tolerant rice cultivar was affected less by water stress than the susceptible cultivar (Jaya).

Title

Studies on the Effects of Relative Humidity of the Atmosphere upon the Growth and Physiology of Rice Plant : V. Influence of humidity on senescence of rice plant leaves

Gen-ichi HIRAI; Osamu TANAKA; Makoto TAKAHASHI; et al. Japanese Journal of Crop Science 1985. doi:10.1626/jcs.54.146

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.
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.
Mechanism Low humidity induced decrease of water content, which stimulated loss of chlorophyll in rice leaves.
Intervention effect High humidity delayed third-leaf senescence in rice, which the authors link to promoted growth.
