The authors found that heat stress dramatically reduced pollen tube survival by up to 77% and slashed seed production by a staggering 87%. Surprisingly, extreme heat eliminated the usual quality differences between cross- and self-pollination. These findings suggest that heatwaves severely compromise both pollen quantity and quality, potentially disrupting plant mating systems and limiting reproductive success in both agricultural and wild plant populations.
