| 英文摘要 | To investigate the effects of moderate water deficit (MD) on ? non-structural carbohydrates (NSC), ? yield and yield components in a sink-limited rice variety under elevated CO2 concentration ([CO2]), a japonica rice (Oryza sativa L.) cultivar Nangeng 9108 was planted at ambient [CO2] (a[CO2]) and elevated [CO2] (e[CO2], a[CO2] + 200 ppm) in open-top chambers with MD treatment set during grain filling stage. The content, accumulation, and translocation of NSC as well as yield components were determined, and the relationships among them were analyzed. Compared to e[CO2] + CK, e[CO2] + MD treatment decreased the content (by 42%) and accumulation (by 57%) of NSC in stems, and greatly promoted NSC translocation (by 325%). At MD treatment, e[CO2] stimulated ATM(NSC) and AC(NSC), and the re-accumulation of stem NSC at maturity was limited under both CO2 treatment. With higher NSC translocation, the 1000-grain weight was lowered, but seed setting rate and harvest index were improved. Grain yield of Nangeng 9108 was not changed by MD treatment, which implied that the sink-limited rice varieties may be more adaptable to balance the survival (root growth to obtain more water) and reproduction with potential drought stress at future CO2-enriched environment. |
