No, corn cannot be used to propagate pineapple. Corn and pineapple are two different plants with different propagation methods.
Pineapple is typically propagated using the vegetative method, which involves using the leafy top or crown of a mature pineapple fruit to grow a new plant. The crown is cut off, allowing it to dry for a few days, and then it is planted in well-drained soil. Over time, roots will develop from the base of the crown, and a new pineapple plant will grow.
On the other hand, corn is usually propagated through seeds. Corn kernels are planted in the soil, and with the right conditions of moisture and temperature, they germinate and grow into corn plants.
Therefore, corn cannot be used to propagate pineapple. Each plant has its own specific propagation method that is most suitable for its growth and reproduction.
