Popis: Seed preconditioning with Ambiol® has been shown to improve germination, growth, and drought tolerance in seedlings of many species. Attempts to understand the mode of action of Ambiol have found that seed preconditioning triggers several new proteins, which suggests that Ambiol-induced benefits may persist beyond seedlings and, perhaps, into the next generation. Seeds were preconditioned with 0 and 10 mg l−1 Ambiol to determine effects on germination, seedling growth, and yield of parent tomato plants. Seeds were collected from plants in each treatment and then sown to determine effects on germination and seedling growth in the next generation. Key parameters such as percent germination, leaf area, shoot mass, root mass, and photosynthesis were significantly improved in parents and in progeny. In addition, there was a 141% increase in tomato yield in preconditioned parents. It was concluded that Ambiol-induced benefits continue throughout plant development and into the next generation, potentially having significant horticultural and economic ramifications.
