The strawberry has already been described, but rarely based on the descriptors of the culture, which is relevant to knowledge of the morphology in their cultivation habitat. The objective of this work was to describe morphologically two strawberry cultivars based on the descriptors of the species and evaluate if there are differences in morphological performance between them when cultivated in protected environment and their responses to morphophenology. The treatments were the strawberry cultivars: Albion (Day-Neutral) and Camarosa (Short-Day), organized in a completely randomized design, with 20 replicates. This work was developed in part as a descriptive research (morphological performance) and part as explanatory research (morphophenology performance). In the descriptive research, were analyzed the morphological performance of the cultivars, based on the morphological descriptors, being the data presented in a descriptive form. In the explanatory research, were analyzed the morphophenology of the two cultivars, being the data submitted to analysis of variance and Tukey test at 5% probability of error. Albion and Camarosa showed similarity in only four characteristics of the 24 evaluated by the descriptors and both had the presence of a botanical structure called hypsophyll. The cultivars presented a morphologically distinct root system, Albion presented a better root system, with deeper roots. Albion was more effective in emitting leaves. It is concluded that both strawberry cultivars, with different photoperiodic responses, presented a botanical structure denominated hypsophyll, which is not included in the morphological descriptors for this species. In addition, Albion is possibly more effective in absorbing water and nutrients, because it has a more extensive root system.
