Question:
High aspartic acid, low nitrogen and sugar content in maize variety makes it resistant to _________
High aspartic acid, low nitrogen and sugar content in maize variety makes it resistant to _________
Show Hint
Biochemical resistance in plants reduces pest survival and reproduction.
Updated On: Mar 6, 2026
- leaf curl
- black rot
- stripe rust
- stem borer
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding plant resistance.
Chemical composition of plants plays an important role in resistance against pests.
Step 2: Role of aspartic acid.
High aspartic acid and low sugar content make maize tissues unsuitable for stem borer feeding.
Step 3: Option analysis.
Stem borer is an insect pest affected by biochemical resistance, unlike fungal or viral diseases.
Step 4: Conclusion.
Thus, maize becomes resistant to stem borer infestation.
