Invasive alien species frequently possess seed related attributes that contribute to invasion success, such as environmental tolerance, numerous seeds, longevity, rapid germination, and high germination rates, among others.These traits can enhance propagule pressure, thus having important implications for management.The genus Kalanchoe contains species widely used in the horticultural trade, but a few have become invasive around the world.We evaluated the performance of Kalanchoe delagoensis seeds of different age to determine the probability of generating a seed bank under dark-light conditions and constant/alternating temperature to assess photoblastic response and seed tolerance to temperature.Seeds were sown following a factorial experiment that comprised four seed ages (5, 8, 11 and 13 months after collection), two temperature conditions (25 °C constant and 16/25 °C alternating), and two light conditions (light and darkness) resulting in 16 experimental treatments with 10 replicates each and 50 seeds per replicate.Seeds were positive photoblastic with no germination under darkness conditions.Final germination percentage ranged from 1.8% to 49.4% among treatments but decreased with seed age and the interaction with temperature.Mean germination time ranged from 4.5 to 10.9 days among treatments.Results suggest that K. delagoensis seeds germinate rapidly, and have a neutral response to the 16/25 °C alternating temperature in germinability.Seed viability rapidly decreases within the first year after the reproductive season, suggesting that this species would only form a transient seed bank.Avoiding inflorescence maturation and covering or burying seeds will contribute to the depletion of the seed bank over the short term and could provide adequate control of invasive K. delagoensis populations.

Management of Biological Invasions

生物入侵管理由 ELIAS DANA 博士于 2010 年创立，是一本开放获取、同行评审的国际期刊，专注于世界各地水生和陆地生态系统生物入侵的应用研究。该杂志致力于弥合科学研究与科学在入侵物种引入和生物多样性保护领域的决策、监管和管理中的应用之间的差距。管理生物入侵是一门危机科学，生物入侵管理旨在提供对问题的见解，记录新的检测、测量和分析形式，并记录该问题的切实解决方案。以及相关国际会议的议事录。作为鼓励对国家和国际重要事项进行知情讨论的平台，我们发表观点论文，突出新出现的问题、展示倡议并提出领先研究人员的意见。

Management of Biological Invasions, founded by Dr. ELIAS DANA in 2010, is an open-access, peer-reviewed international journal that focuses on applied research on biological invasions in aquatic and terrestrial ecosystems worldwide. The journal aims to bridge the gap between scientific research and its application in decision-making, regulation, and management concerning the introduction of invasive species and biodiversity conservation. Biological invasion management is a crisis science that seeks to provide insights into the issues at hand, document new forms of detection, measurement, and analysis, and record practical solutions to these problems. Additionally, we publish proceedings from relevant international conferences. As a platform for encouraging informed discussions on national and international important matters, we publish opinion papers that highlight emerging issues, showcase initiatives, and present the views of leading researchers.
