摘要

Flooding is a major risk to fresh vegetable production in southern Florida. Pot experiments were conducted, to assess the effects of various foliar chemical treatments imposed on flooded corn plants (Zea mays L. var. BSS9686). The effects of foliar treatments were evaluated by measuring leaf greenness using a SPAD meter (SPAD 502). Flooding significantly decreased the SPAD readings. Foliar N sprays significantly influenced leaf greenness according to the SPAD readings. Correlations between SPAD readings and leaf N were significant for chemicals with fertilizers but not for chemicals with growth regulators and fungicides. It is concluded that foliar-applied N ameliorated the effects of flooding by restoring chlorophyll concentration in the leaves. Foliar growth regulators and fungicides, however, had no significant effect in terms of alleviating waterlogging stress.
