Key message

Campomanesia spp produce seeds with high viability and vigor which are tolerant to desiccation but not to cold temperature.

Abstract

The genus Campomanesia has ecological and economic importance in the Atlantic Forest, but 19 of its species are on the red list of threatened species of the International Union for Conservation of Nature (IUCN). There is a lack of studies on seed biology and considerable urgency in developing strategies for their ex-situ conservation and subsequent use in restoration. In this study, we analyzed the viability and vigor in seeds of three Campomanesia species under different temperatures to determine the ideal conditions for storage. Additionally, we analyzed the factors that influence their response in storage. Differences in germination, tetrazolium and germination speed index were compared for three Campomanesia species with different distributions in the Brazilian Atlantic Forest (C. xanthocarpa, C. reitziana and C. littoralis). Seeds of three species were stored in two water contents, three temperatures, for six period and liquid nitrogen. The three species presented seeds sensitive to freezing (−20 °C and liquid nitrogen). C. xanthocarpa seeds showed a short life during storage at 25 °C and 8 °C. C. reitziana and C. littoralis seeds with initial water content showed high germination up to 120 days of storage at 8 °C and these values were higher than seeds with water content of 0.16 g H₂O. g dw^− 1 stored under the same conditions. Finally, our results of the characterization of the tolerance to drying and the behavior during storage at different temperatures of C. xanthocarpa, C. littoralis and C. reitziana are the base line for the generation of successful conservation strategies, both in situ and ex situ.

巴西南部三种特有树种种子贮藏期间的活力和生存力

【关键信息】甘薯属植物的种子活力和活力高，耐干燥，但不耐低温。摘要在大西洋森林中，Campomanesia属具有重要的生态和经济意义，但其中19种已被列入国际自然保护联盟(IUCN)濒危物种红色名录。目前对种子生物学的研究还很缺乏，迫切需要制定种子的迁地保护和随后的恢复利用策略。本研究分析了不同温度下三种坎马马属植物种子的活力和活力，以确定理想的贮藏条件。此外，我们还分析了影响其储存反应的因素。比较了巴西大西洋森林中分布不同的3种Campomanesia (C. xanthocarpa、C. reitziana和C. littoralis)的萌发率、四氮唑含量和萌发速度指数的差异。将3种植物种子分别在2种含水量、3种温度、6个周期和液氮条件下贮藏。3种种子对冷冻(- 20°C和液氮)敏感。在25°C和8°C贮藏条件下，黄杉种子的寿命较短。在8°C条件下，初始含水量为0.16 g H2O的种子在120 d内萌发率均高于初始含水量为0.16 g H2O的种子。相同条件下存储的G dw−1。最后，我们的研究结果表征了黄卡柏(C. xanthocarpa)、littoralis (C. littoralis)和reitziana (C. reitziana)在不同温度下对干燥的耐受性和储存行为，为制定成功的原位和非原位保护策略提供了基础。
