Values are means of three replicates ± SE. Values followed by the similar lower case letters within columns for a maize hybrid don’t differ significantly according to Newman–Keuls test (P < 0.05).Ck, control (100% FC); LD, low drought (80% FC); MRD, moderate drought (60% FC); and SD, severe drought (40% FC); FC, Field capacity.
