Gibberellins are known to promote bolting, which is defined as internode elongation just prior to flowering. Which of the following pairs of plants typically exhibits this phenomenon?

Step-by-step solution

According to NCERT, gibberellins promote bolting (internode elongation just prior to flowering) in beet, cabbages and many plants with a rosette habit. Ethylene is responsible for synchronising fruit set in pineapples and inducing flowering in mango. While gibberellins increase the length of sugarcane stems, rapid internode or petiole elongation in deep water rice plants is promoted by ethylene. Gibberellins are used to improve the shape of apples, and auxins are used to induce parthenocarpy in tomatoes. Answer: Be
