Treatment method for improving low-temperature resistance of tomato anther and application of treatment method
By spraying tomato flowers with methyl jasmonate solution before they fully open, the problem of reduced pollen viability and germination rate in tomatoes under low temperature conditions was solved, thus improving the low temperature resistance of tomatoes and increasing fruit yield and quality.

AI Technical Summary
Tomatoes are susceptible to stress in low-temperature environments, leading to decreased pollen viability, reduced pollen tube germination rate, and reduced fruit yield. Existing technologies have not been able to effectively address this problem, especially with limited research on low-temperature resistance during the reproductive growth period.
Spraying methyl jasmonate solution (MeJA) at a concentration of 50-150 μM, especially 100 μM, during the tomato anther tetrad stage can promote normal degradation of the tapetum, increase pollen survival rate and pollen tube germination rate, and alleviate the adverse effects of low temperature damage on the fruit.
It significantly improved the tomato fruit set rate under low temperature conditions, improved fruit phenotype, including indicators such as seed number, fruit weight and fruit diameter, and effectively mitigated the negative impact of low temperature injury on tomato yield.
