Question

Maize plants are resistant to maize stem borers due to

• A. low nitrogen, high sugar and low aspartic acid content
• B. low sugar, high nitrogen and high aspartic acid content
• C. low aspartic acid, high nitrogen and high sugar content
• D. low nitrogen, high aspartic acid and low sugar content

Answer 1

The correct option is D low nitrogen, high aspartic acid and low sugar content

Agricultural pests are organisms that attack agricultural crops and destroy them, leading to huge crop losses. Some crop plants naturally develop resistance to pests as a result of morphological, physiological or biochemical characteristics in them.

In maize crop certain biochemical characteristics like low nitrogen, low sugar and high aspartic acid content helps resist against maize stem borers (insect larvae which bore into plant stems).
