مستخلص: | Asexual reproduction is a common phenomenon in plants. Diverse studies have found a positive relationship between both aboveground and belowground biomass and the production of clones. In carnivorous plants, a positive relationship between the number of prey captured and clonal growth has been documented. However, there are not studies evaluating the importance of resource availability (measured as plant biomass) and the production of structures of asexual propagation in plants with the carnivore habit. Pinguicula heterophylla(Lentibulariaceae) is a carnivorous plant endemic to Mexico, which produces clones on the tip of the leaves. The objective of this study was to evaluate the importance of resource availability (measured as both aboveground and belowground plant traits) on clonal growth of P. heterophylla. Number of clones, as well as aboveground traits (number of leaves; leaf length, width and area; and total leaf area per individual plant) and belowground biomass (hibernaculum length, width, thickness, area and volume; and dry weight) estimators were quantified in each of 40 individuals. Leaf number, total leaf area per individual, and hibernaculum length and area were significantly greater in plants with clonal growth. Leaf length and number of leaves per individual explained most of the variation in the number of clones produced by each individual plant. Our results suggest that resources available within both aboveground and belowground plant organs have an important role favoring asexual reproduction in P. heterophylla; however, it seems that the number of clones produced by each plant depends from aboveground traits. |
