The production of marine microalgae provides a sustainable solution for agriculture, acting as biostimulants to enhance seed germination, vigor, and early growth. In the present work, the parameters of pH, airflow, and dilution speed were established to produce biomass of two species of marine algae ( and sp.); in addition, its capacity to stimulate the germination of bean seeds was evaluated. The experimental treatments included three biomass concentrations (C) of both microalgae species (0.5, 1, and 1.5 g·L) and a control (distilled water) at two temperatures (25 and 35 °C). The rate, index, average time, time at 50% germination, and vigor were evaluated. The results indicated that the highest yield of microalgae biomass was obtained with D = 0.3 day for and 0.2 day for sp. Microalgae biomass showed activity as a biostimulant on germination, improving the germination rate and reducing the germination time with better vigor for the seedlings at each of the evaluated concentrations.
海洋微藻的生产为农业提供了一种可持续的解决方案，可作为生物刺激剂来提高种子发芽率、活力和早期生长。在本研究中，确定了pH值、气流和稀释速度等参数，以生产两种海洋藻类（和种）的生物质；此外，还评估了其刺激豆类种子发芽的能力。实验处理包括两种微藻物种的三种生物质浓度（C）（0.5、1和1.5 g·L）以及在两个温度（25和35°C）下的对照（蒸馏水）。评估了发芽率、发芽指数、平均时间、50%发芽时间和活力。结果表明，对于，D = 0.3天，对于种，D = 0.2天，可获得最高的微藻生物质产量。在每个评估浓度下，微藻生物质对发芽表现出生物刺激活性，提高了发芽率，缩短了发芽时间，且幼苗活力更好。
