摘要

The maricá (Mimosa bimucronata (DC) O. Kuntze) is a forest species, belonging to the family Fabaceae, considered endemic to the Atlantic Forest biome. The present work aimed to study the germinative behavior of M. bimucronata seeds under different temperatures and light qualities, as well as to evaluate the effect of the amount of water (humidity) in the substrate and the osmoconditioning during germination. Thus, the experiment was performed using a completely randomized design. The treatments were distributed in a 4 × 4 factorial scheme (temperatures and light qualities), with 4 replicates of 25 seeds each. The means were compared by Tukey's test at 5% probability. The volume of water and osmoconditioning of substrate was evaluated and data were subjected to regression analysis. The following variables were analyzed: first count of germinated seeds, germination, germination speed index, and electrical conductivity. The results revealed that seeds are neutral photoblasts, needing a constant temperature of 30 ℃ along with a white light for appropriate germination and vigor. Seeding on two sheets of paper towel moistened with water volume (mL) from 2.62 to 2.70 times was more suitable for conducting the germination test. The osmotic conditioning was inefficient in maintaining germination of these seeds.

Kuntze）是一种属于Fabaceae的森林物种，被认为是大西洋森林生物群落特有的。本工作旨在研究在不同温度和光照条件下双歧杆菌种子的萌发行为，并评估发芽过程中基质中水分（湿度）和渗透调节的影响。因此，使用完全随机的设计进行了实验。处理以4×4阶乘方案（温度和光照质量）分配，每组25粒种子重复4次。通过Tukey检验以5％的概率比较了平均值。评价水的体积和基质的渗透调节，并对数据进行回归分析。分析了以下变量：发芽种子的首次计数，发芽，发芽速度指数和电导率。结果表明，种子是中性的光母细胞，需要30℃的恒温以及白光才能适当发芽和保持活力。在两张纸巾上加水量（mL）2.62至2.70倍的种子更适合进行发芽试验。渗透条件不能有效维持这些种子的发芽。
