Abstract

The present study aimed to analyze the physical characteristics, seed health, and seedling emergence of nine Ilex paraguariensis mother trees. Physical characterization included determining the thousand-seed weight, number of seeds per kilogram, and moisture content. Viability and embryonic development were determined by the tetrazolium test, using five replications of 20 seeds for each mother tree. Seedling emergence was evaluated under three treatments: non-stratified seeds, seeds stored for 70 days

不同母树的 Ilex paraguariensis 种子和幼苗的物理特性、活力和卫生分析

本研究旨在分析九棵 Ilex paraguariensis 母树的物理特征、种子健康状况和出苗情况。物理特征包括千粒重、每公斤种子数和含水量。活力和胚胎发育通过四氮唑试验进行测定，每棵母树用 20 粒种子进行五次重复。在三种处理方式下对出苗率进行了评估：未分级种子、贮藏 70 天的种子、贮藏 70 天的种子和贮藏 70 天的种子。
