英文摘要	Drought stress is considered to be the main source of yield reduction around the world. Improving plant performance under stressful environments by understanding growth and physio-biochemical responses are important. However, the detail mechanism of how boll capsule wall and subtending leaves anatomy, physiobiochemical characteristics and key enzymes i.e. Ribulose-1,5-bisphosphate carboxylase (RUBPC) and phosphoenolpyruvate carboxylase (PEPC) affect cotton (Gossypium hirsutum L.) yield have not yet been reported. To cover this knowledge gap, a two-year field experiment evaluated three drip irrigation rates [W-1 (4800 m(3) ha(-1)), W-2 (3840 m(3) ha(-1)) and W-3 (2880 m(3) ha(-1))] effects on cotton main stem leaves, boll subtending leaves, capsule wall anatomy, biomass accumulation, RUBPC and PEPC activity. Compared with W-1, W-2 had 10.4-15.7 %, 8.3-24.6 %, 4.4-22.7 % and 5.0-15.3 % higher boll subtending leaf net photosynthetic rate, chlorophyll content, RUBP and PEPC activity at 21-42 days after anthesis. The palisade tissue thickness at 35 DAA (days after anthesis) and the ratio of palisade tissue to sponge tissue (p/s) of boll subtending leaf during 21-49 DAA were 7.7 % and 3.6-10.2 % higher for W-2 over W-1. Under W-2 treatment,improvements in these attributes significantly prolonged biomass accumulation rate (T, 6.9 d and 22.1 d) of main stem leaves and boll subtending leaf resulted in the maximum growth rate of seed cotton weight (Vx, 0.195 g d(-1)). Conclusively, higher photosynthetic capacity of the boll subtending leaves during 21-42 DAA and thicker capsule wall are the main drivers for achieving higher seed cotton weight under limited drip irrigation systems in arid region.
