Variety traits
Petunia x hybrida hort. ex E. Vilm.
This trait describes the genetic ability of petunias to form long lateral shoots and the branching pattern that determines the plant habit, ranging from compact mounded to trailing.
In the reference 22 varieties crop Garden petunia, where this is mentioned in the description.
In Petunia × hybrida agronomy, plant habit classification is used to characterize trailing habit: the trailing (ampelous) type is characterized by early and vigorous growth of lateral shoots from 60 to 120 cm in length, whereas the mounded type is distinguished by limited shoot growth and a dense plant structure. Intermediate forms combine a compact center with moderate stem expansion.
Evaluation of this trait is based on a set of morphological indicators, including shoot length in centimeters, the intensity of autonomous branching of axillary buds, and internode length. Increased internode length contributes to the formation of a pronounced cascading effect.
The choice of plant habit determines the intended use of a cultivar in landscape design. Varieties with pronounced trailing habits are preferred for hanging baskets and containers due to their flexible stems, while upright forms are more suitable for open ground to prevent lodging.
Agrotechnical factors, such as light intensity and nitrogen nutrition, significantly influence the expression of trailing habit. Unbalanced growing conditions can cause excessive stem elongation even in genetically compact varieties, which increases transpiration and necessitates adjustments to the irrigation regimen.
