Abstract
The apoplastic tracer Sulforhodamine G was used to study the maturation of functional, water-conducting xylem vessels into developing cotton fruits and to quantify apoplastic water flow to cotton leaves, bracts and fruits. Segments of cotton branches with one sympodial leaf and subtended fruit were placed in a vial containing a 0.05% (w/v) solution of Sulforhodamine G in distilled water and allowed to transpire freely for 2.5 h, after which the dye was extracted from the different tissues and quantified spectrophotometrically. The value obtained was used as a quantitative indicator of xylem transport to the different organs
