Article Synopsis
- The study examined how elevated CO2 levels (FACE) and nitrogen supply interacted to affect the nitrogen dynamics in winter wheat (Ningmai 9) over different growth stages from 2001 to 2003.
- Results indicated that while nitrogen content in the wheat decreased significantly under FACE conditions, nitrogen accumulation increased, especially during the middle growth stage.
- Additionally, FACE improved nitrogen use efficiency for biomass and grain yield across all stages, while nitrogen application boosted nitrogen content and uptake but lowered overall use efficiency.

A free-air CO2 enrichment (FACE) experiment was conducted in 2001-2003 to study the effects of predicted higher CO2 levels on the dry matter (DM) production and allocation in winter wheat variety Ningmai 9. The results showed that under FACE, the DM production had an increase of 10. 8% , 31.

To investigate the effects of predicted higher CO2 levels on the growth duration, plant height, yield, and yield components of wheat (Triticum aestivum L.), a free-air CO2 enrichment (FACE) experiment with weak gluten variety Ningmai 9 was conducted at Anzhen of Wuxi in Jiangsu Province in 2001-2002 and 2002-2003 growth seasons. The target [CO2] in FACE plots was 200 microl x L(-1) above that in ambient air.
