Abstract

The aim of this study was to ascertain the effect of two herbicides on the relative water content in three weeks old Zea mays seedling.Foliar application of the two herbicides resulted in obvious reductions of the relative water content. With oxyfluorfen, percentage reductions compared to control  amounted to 9%, 11%, 7%, 11% and 14% after 12, 24, 36, 48 and 60 h respectively, whereas with Pendimethalin percentage diminishments were 8%, 10%, 12%, 15% and 20% after 12, 24, 36, 48 and 60 h respectively.
