What is the ideal temperature range for fruit set?

Explanation:
Temperature during flowering and fruit set strongly influences pollen viability and fertilization. Pollen and pollen-tube growth work best in warm, moderate conditions, roughly in the mid-20s to low-30s Celsius. If it's cooler, fertilization slows and set drops; if it gets too hot, pollen viability and stigma receptivity can decline, leading to poor fruit set. So the range around 26–32°C provides the best balance for successful fruit set, while cooler ranges are less favorable and very hot ranges reduce set.
