Replication Data for: Field resistance of onion cultivars to onion thrips and effect of the mechanical injury on the level of biochemical compounds in onion leaves.

Data associated with the research conducted to identify onion genotypes possibly resistant to the onion thrips infestation under field conditions and to determine whether there is a relationship between any biochemical and anatomical features of onion plants and their resistance to the thrips. Additionally, an attempt was made to determine the influence of mechanical damage on the content of several biochemical compounds in leaves of examined onion cultivars.
