Question

Maize variety resistant to stem borer shows

• A. High content of nitrogen
• B. Low nitrogen content
• C. Low Aspartic acid
• D. High Malic acid

Answer 1

The correct option is B

Low nitrogen content

Biochemical and physiological characteristics such as high aspartic acid, low nitrogen and sugar content leads to pest resistance. For e.g. in maize, the low nitrogen content leads to non-preference by the maize stem borers.
