Abstract
Objective: To evaluate different pre-germination treatments to accelerate, synchronize, and increase seed germination and the development of vigorous tomato seedlings by evaluating the efficiency of different treatments based on hydropriming methods, chemical compounds, plant extracts, and biopriming.
Design/methodology/approach: Germination rate, speed, and timing were determined using variables such as total germination, maximum daily germination, germination interval, and T50. Vigor was measured using stem and root lengths and dry matter weight. Analysis of variance was applied for a completely randomized design for each variable.
Results: Several treatments increased the germination potential of tomato seeds and were successful in improving seedling characteristics. Furthermore, it was impossible to alter the temporal dynamics of the germination process.
Study limitations/implications: Future studies suggest evaluating the most relevant results of this work on production and resistance to environmental stressors.
Findings/Conclusions: Hydropriming and biopriming with little-known Bacillus and Pseudomonas species were positive for germination and seedling vigor indicators, respectively. Garlic, onion, and chili extracts had positive effects on both germination and development parameters.
