Blossom set is used to stimulate early fruit set on which crop?

• A. Cucumbers
• B. Peppers
• C. Lettuce
• D. Tomatoes

Answer: (D)

Blossom set treatments use plant hormones to signal flowers to begin developing into fruit, even when pollination is poor or conditions aren’t ideal. Tomatoes respond particularly well to this hormonal cue, so applying blossom set encourages the ovary to start growing into fruit early, helping growers achieve fruit development sooner and with more reliability under stressful conditions like cool temperatures or high humidity. Since tomatoes are a fruiting vegetable and especially responsive to these signals, this method is most commonly used with them. Lettuce doesn’t form fruit, so blossom set isn’t applicable there, while peppers and cucumbers can set fruit with pollination, but the practice is most strongly associated with tomatoes in horticulture.
