Fig. 4.

(I) PCR amplified product of mixed sample (1: Black piper with papaya seed, 2: Black cumin with red creole onion, 3: Lemon grass with perennial ryegrass, and 4: Husk with garden cress) revealed inappropriate bands with primer set 1 while amplified product of single sample (a: papaya seeds, b: red creole onion, c: perennial ryegrass, and d: garden cress) showed single sharp band of targeted region, similarly (II) exhibited impure band with primer set 2. Whereas “M” is the molecular weight marker (ladder genome) and “E” is the empty.
