Table 1.

Protein concentration in Zea mays leaves and roots exposed to abiotic, i.e. MJ (10 µM applied for 24 h) or both MJ (10 µM applied for 24 h) and Cu (50 µM applied for 5 h), and biotic (T. caelestialium) factors

Treatment	Protein concentration [% of control without insect]
	Leaves	Roots
MJ + Cu without insect	114 c	128 a
MJ without insect	128 b	119 a
Control with insect	113 c	86 c
MJ + Cu with insect	124 b	84 c
MJ with insect	145 a	102 a

Different letters indicate significant differences between the treatments. Values are the means of three–five separate experiments ± SE (three replicates each)
