Which of the following statements is incorrect?
Options
- AShoot apices those modify themselves into flowering apices, cannot perceive photoperiods.
- BSugarbeet, cabbage and carrots are monocarpic plants.
- CTo initiate flowering, LDP must be exposed to light for a period less than critical duration.
- DEthephon causes thinning of cotton, cherry & walnut.
Correct answer
C. To initiate flowering, LDP must be exposed to light for a period less than critical duration.
Step-by-step solution
Long Day Plants (LDP) requires exposure to light for a period exceeding critical duration to induce flowering. Ethephon hastens fruit ripening in tomatoes and apples and accelerates abscission in flowers and fruits (thinning of cotton, cherry, walnut). Shoot apices those modify themselves into flowering apices, cannot perceive photoperiods. Biennial monocarpic plants that flower and then die in the second season. Some examples are sugar beet, cabbage, carrot, etc
