The objective of this study was to identify a boron(B)application strategy maximizing cotton yield.In a two-year experiment across two soil types with three B application rates,B availability significantly regulated boll biomass accumulation rate in a 12-19-d post-anthesis window;B concentrations of 41-74 mg B kg-1 in leaves subtending bolls maximized boll weight;and moderate B application increased source-sink carbon flux by increasing net photosynthetic rate,sucrose biosynthesis,and phloem loading efficiency.Integrating these three findings will increase photoassimilate partitioning to reproductive sinks,boosting cotton yield and B-use efficiency. 展开更多
