Abstract
Abstract Flowering in bamboo is an unusual event. Documenting flowering individuals or populations provides valuable information about bamboo life cycles. Guadua trinii is endemic to northeastern Argentina, southern Brazil, Paraguay and Uruguay. We here report the flowering of this species in native and cultivated stands in Argentina and confirm its flowering cycle to be of 30-33 years.
Highlights
Flowering in bamboo is an unusual event
Wherever bamboos constitute an important component of the forest, they have profound effects on the dynamics and structure of plant communities (Holz & Veblen 2006; Campanello et al 2007; Caccia et al 2009), and on the population dynamics of animal species that rely on bamboos for refuge or feeding (Piudo et al 2005; Gallardo et al 2008; Areta et al 2009, 2016; Piudo & Monteverde 2016)
Little was known about the intervals between successive mass flowering events of native American bamboos (Parodi 1955; Vega & Cámara Hernández 2008), until Guerreiro (2014) gathered information from herbarium specimens to reconstruct flowering dates and estimate flowering cycles of 16 species of woody bamboos native to southern South America
Summary
Flowering in bamboo is an unusual event. Documenting flowering individuals or populations provides valuable information about bamboo life cycles. The flowering cycle of the woody bamboos varies a great deal, from 3 to 120 year intervals (Janzen 1976). Little was known about the intervals between successive mass flowering events of native American bamboos (Parodi 1955; Vega & Cámara Hernández 2008), until Guerreiro (2014) gathered information from herbarium specimens to reconstruct flowering dates and estimate flowering cycles of 16 species of woody bamboos native to southern South America.
