    Jachetta, John Joseph
    Abstract:
    Apoplastic distribution patterns of atrazine [2-chloro-4-(ethylamino)- 6-(isopropylamino)-s-triazine], glyphosate [N-(phosphonomethyl)- glycine], the naturally occurring apoplastic leaf solutes, and the apoplastic dye PTS (trisodium 3-hydroxy-5,8,10-pyrenetrisulfonate) were compared. Aliquots of sap were expressed from intact sunflower leaves in a pressure chamber over intervals of 0.2 to 0.4 bars. Three distinct fractions were detected...
