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).

Root Traits Responses to Irrigation Intervals in Rice (Oryza sativa)

Mahmoud M. Gaballah; Adel M. Ghoneim; Mohamed I. Ghazy; et al. International Journal of Agriculture and Biology 2021. doi:10.17957/ijab/15.1804

Other claims from this paper (9)

Intervention effect Prolonged irrigation intervals reduced root architecture traits.
Intervention effect Plant height, panicle number, and grain yield significantly decreased across irrigation intervals.
Intervention effect Sterility significantly increased across irrigation intervals.
Intervention effect Water use efficiency significantly increased across irrigation intervals.
Association Grain yield was positively correlated with root:shoot ratio, relative water content, and panicle number.
