a For each response variable, values (means of four replicates) not sharing a common letter, lower case (e.g. a, b) in the vertical columns for each plant part within every harvest and upper case (e.g. A, B) in the horizontal lines for each plant part between harvests (D50, D65), differ significantly (P<0.05) from each other (DMRT).
