Importance of bracts in the carbon economy of cotton

, : Importance of bracts in the carbon economy of cotton. Arkansas Farm Research 39(4): 4

In field trials in 1989 at Fayetteville, Arkansas the effects of irrigation (10 mm/d), moderate water stress (4 mm/d) and severe water stress (no irrigation) on leaf water potential and photosynthesis and respiration of leaves and bracts at main stem node 8 were studied in cotton Stoneville 506. Sympodial leaves had high photosynthetic rates at anthesis, which decreased with age.
