Abstract

Red chili is a crucial horticultural crop in Indonesia. The increasing demand for high-quality chili necessitates seeds with optimal germination and growth. Spirulina platensis, a microalgae species, can be cultivated in waste media such as Sugar Mill Effluent (SME). Moreover, Spirulina contains phytohormones that can stimulate seed germination. This study investigated the impact of various concentrations and soaking times of S. platensis solution on red chili seed quality. A factorial Completely Randomized Design (CRD) was employed with 5 levels of microalgae biomass concentration: control (untreated seeds), 0, 30, 45, and 60% and 3 levels of soaking time: 1, 2, and 3 hours. Data analysis involved ANOVA and Bonferroni post-hoc tests at a 5% level using GraphPad Prism version 5.01. The results demonstrated seed priming application using S. platensis significantly enhanced seed vigor. The S. platensis treatment at 60% concentration for 2 hours significantly reduced MGT by 1 day, while 30%-2 hours and 60%-3 hours treatments exhibited the highest germination rate (100%), vigor index (49.17% in 30%-2 hours), seed growth simultaneity (85.56% in 60%-2 hours and 83.33% in 30%-2 hours), and growth rate (11.48% in 60%-3 hours and 11.11% in 30%-2 hours), with the 60%-3 hours treatment showing the longest shoot (2.73 cm) and radicle (8.13 cm) lengths, compared to the control. These findings suggest that S. platensis priming can be a promising approach for improving seed quality and crop establishment.

Abstract

Spirulina platensis is a microalgae that can grow in waste media, including Sugar Mill Effluent (SME). In addition, Spirulina contains phytohormones that can be utilized to enhance seed germination. Cultivating microalgae will produce biomass that can be used for priming cucumber seeds. This research aims to determine the effect of Spirulina biomass and soaking time on the germination of cucumber seeds. In this research, a factorial Completely Randomized Design (CRD) was used, consisting of 5 levels of microalgae biomass concentration: control (untreated seeds), 0, 30, 45, and 60%, with soaking time of 3 levels: 1, 2, and 3 hours. The results demonstrated that Spirulina can grow in SME-based media, as indicated by the increase in size and density of microalgae cells.  Analysis of the seed priming test results of 45% algae biomass concentration for 1 and 3 hours showed a significant effect on the parameter of vigor index, seed growth rate, and simultaneous seed growth. In the treatment with a 60% concentration and soaking time of 1, 2, and 3 hours, significant effects were observed on the parameters of MGT, vigor index, seed growth rate, and shoot length. Even though the 45% and 60% treatments showed no significant differences in the few parameters, the priming with Spirulina platensis exhibited no decrease in cucumber seed germination, these applications indicated no decrease in seed germination. This demonstrates that priming treatment with Spirulina platensis is not toxic to seedling growth.
