Correct answer: B. Waxiness of leaves
- A. High aspartic acid
- B. Waxiness of leaves
- C. High silica content
- D. High benzol alcohol
Explanation
In barley, leaf waxiness can deter feeding and reduce acceptance by the cereal leaf beetle, making it a recognized resistance-associated trait. High silica is more broadly linked with resistance to some herbivores but is not the expected association here.
