Abstract

Underground organs are important for the persistence of plants in seasonal environments, as they store substances and contain buds. The underground organs of Sisyrinchium vaginatum store soluble carbohydrates, but how phenology affects their dynamics is unknown. This study aimed to analyze the contents and composition of soluble carbohydrates in underground organs of S. vaginatum at different phenological phases. The contents and composition of soluble carbohydrates were analyzed during sprouting, vegetative growth I and II, seed dispersal and senescence. Carbohydrate storage was greater when vegetative growth stabilized, with the lowest levels occurring during more energy-demanding phases. myo-Inositol, glucose, fructose, sucrose, and raffinose-like sugar were identified, with last two being predominant. The proportion of majority of these sugars differed among phenological phases. The variations in soluble carbohydrates were associated with phenological shifts and may contribute to the persistence of S. vaginatum in seasonal environments.
