Abstract

Seeds are a primary source for generating plants for large-scale restoration and understanding the requirements for seed germination and establishment is fundamental to ecological restoration. Seed germination traits are central to defining the germination niche and identifying traits that may limit seedling establishment provides insights into how seeds may interact with the abiotic environment and the soil substrates specific to each restoration site and informs seed management practices. In this paper we review seed trait data derived from research to improve restoration practice across diverse ecosystems within Western Australia. We compile and evaluate seed trait data for up to 300 seed collections of 287 species that are used in restoration programmes to identify species, lifeform, and region-specific variation in seed dormancy, maximum germination, germination speed, base water potential, and germination niche breadth. Through a synthesis of this data, we outline our ecologically-guided approach to identifying key seed traits that support plant regeneration to improve the success of seed-based restoration across the biodiverse Western Australian landscape.

种子性状为生物多样性生态恢复提供萌发生态位信息

种子是大规模恢复植物的主要来源，了解种子萌发和建立的要求是生态恢复的基础。种子萌发特征是确定萌发生态位和识别可能限制幼苗建立的特征的核心，提供了种子如何与非生物环境和每个恢复地点特定的土壤基质相互作用的见解，并为种子管理实践提供了信息。在本文中，我们回顾了来自研究的种子性状数据，以改善西澳大利亚州不同生态系统的恢复实践。我们收集和评估了287个物种的300个种子标本的种子性状数据，这些数据用于恢复项目，以确定种子休眠、最大萌发、萌发速度、基本水势和萌发生态位宽度的物种、生命形式和区域特异性差异。通过对这些数据的综合，我们概述了我们的生态指导方法，以确定支持植物再生的关键种子性状，以提高西澳大利亚州生物多样性景观中基于种子的恢复的成功。
