Plants encounter numerous adversities during growth, necessitating the identification of common stress activators to bolster their resistance. However, the current understanding of these activators' mechanisms remains limited. This study identified three anti-stress activators applicable to apple trees, all of which elevate plant proline content to enhance resistance against various adversities. The results showed that the application of these sugar substitutes increased apple proline content by two to three times compared to the untreated group. Even at a lower concentration, these activators triggered plant stress resistance without compromising apple fruit quality. Therefore, these three sugar substitutes can be exogenously sprayed on apple trees to augment proline content and fortify stress resistance. Given their effectiveness and low production cost, these activators possess significant application value. Since they have been widely used in the food industry, they hold potential for broader application in plants, fostering apple industry development.
植物在生长过程中会遇到许多逆境，需要识别常见的胁迫激活剂来增强其抗性。然而，目前对这些激活剂机制的理解仍然有限。本研究鉴定了三种适用于苹果树的抗逆激活剂，它们都能提高植物脯氨酸含量，增强对各种逆境的抗性。结果表明，与未处理组相比，这些糖替代品的应用使苹果脯氨酸含量增加了两到三倍。即使在较低的浓度下，这些激活剂也能触发植物的抗逆性，而不会影响苹果果实的品质。因此，这三种糖替代品可以外源喷施到苹果树上，增加脯氨酸含量，增强抗逆性。鉴于它们的有效性和低成本，这些激活剂具有重要的应用价值。由于它们已广泛应用于食品工业，因此它们在植物中的应用具有很大的潜力，有助于苹果产业的发展。
