Research on the changes in wettability of rice ( <i>Oryza sativa</i> .) leaf surfaces at different development stages using the <scp>OWRK</scp> method

Abstract

The changes in value of CA and surface free energy (SFE) both reflect the changes of the leaf surface wettability, while the SFE value shows better in wettability characterizing. Obvious rice leaf wettability changes were found on different development stages, which may be beneficial for researches in agrochemical sprays wetting and spreading behavior. Factors influencing these alterations were discussed.
