This two-year research (2014-2015) aimed to compare the vegetative growth of three Mexican strawberry (Fragaria × ananassa) cultivars (‘CP-Jacona’, ‘CP-Zamorana’ and ‘CP-06-15’) while grow under a high tunnel in two bed systems: fertigation (soil) and soilless (volcanic gravel). Three experiments were performed in a split-plot design in central Mexico. Two evaluations for vegetative propagation and one for fruit production were carried out. Regarding cultivars, no significant differences were detected concerning fresh weight distribution nor leaf area, but the number of runners was different in 2014 and 2015 and the number of primary sprouts was different in 2014. In respect of bed system, plants had a stronger growth while growing as vegetative in gravel. In 2014 and 2015, leaf area (p≤0.0003 and p≤0.0001), root fresh weight (p≤0.006 and p≤0.0001) and leaf fresh weight (p≤0.002 and p≤0.0003) were higher in plants from gravel than those from soil. In 2015, number of runners (p≤0.012) and number of sprouts (p≤0.004) were higher in gravel than in soil. Also, sprouts achieved a stronger root in gravel compared with those in soil, but this effect was only significant in 2014 (p≤0.006). There was no effect from bed system on leaf fresh weight from the sprout. Crown fresh weight from the sprout was only affected by bed system in 2015, when it was higher in soil (p≤0.029). When plants were grown for fruit production, root fresh weight was higher in plants from gravel compared with those from soil (p≤0.03), but there was no effect of bed system on aboveground fresh weight, including that for fruit. It is concluded that soilless with volcanic gravel in a bed, under a high tunnel in central Mexico, is a suitable system for vegetative propagation of ‘CP-Jacona’, ‘CP-Zamorana’ and ‘CP-06-15’.
