“…The pathogenicity tests performed on cumin seeds showed variation in the pathogenicity of isolates, as cumin seed germination was significantly affected by the F. solani pathogen. Different factors such as temperature, humidity, and moisture also influence the seed germination [14,42], whereas, in this study, ideal conditions (for cumin seed germination) were maintained, but the seeds demonstrated lower germination (%), potentially due to the pathogenic stress induced by F. solani.…”

“…Considering these serious problems of fungicides, various researchers are currently focusing on eco-friendly approaches for the control of plant diseases by using fungal and bacterial species with antimicrobial potential. Various fungal and bacterial endophytes with biocontrol potential have been widely used against various phytopathogens [13], and their direct application or seed priming can assist in reducing disease [14]. In fungal endophytes, hundreds of Trichoderma species used as biocontrol agents, including T. harzianum, T. atroviride, T. longibrachiatum [15], T. viridae, and T. polysporum, have been widely used against various plant diseases.…”

Root rot disease of Cuminum cyminum caused by Fusarium solani is one of the most destructive diseases threatening cumin production. The present study investigates the biocontrol potential of some endophytes against F. solani and their effect on the induction of defense-related enzymes in a greenhouse. The results herein presented illustrate the strong biocontrol potential of three (out of twelve) endophytes. During the in vitro assay, three isolates demonstrated strong mycelial growth inhibition of F. solani: isolates 3, 4, and 9, with 87%, 65%, and 80% reductions, respectively, with respect to the control (100%). These isolates were identified as Trichoderma harzianum, T. longibrachiatum, and Chaetomium globosum, which produce siderophore and indole-3-acetic acid (IAA). Cumin seed priming with the culture filtrates of T. harzianum, C. globosum, and T. longibrachiatum positively affected the seed germination, as a higher germination (%) of culture filtrate-treated seeds was observed followed by infected and healthy control/untreated seeds. In the greenhouse, the application of T. harzianum, T. longibrachiatum, and C. globosum caused a reduction in disease severity (67.7%, 58.1%, and 59.3%, respectively) on cumin plants, with a lower disease severity (20%, 26%, and 25%, respectively) recorded in treated plants compared to the infected control (62%). Furthermore, a significant increase in defense-related enzymes in culture filtrate-treated cumin plants was recorded. Higher peroxidase (PO), polyphenoloxidase (PPO), and phenylalanine ammonia-lyase (PAL) activity, and a higher content of phenolic compounds, were found in culture filtrate-treated plants. These results indicate that the culture filtrates of these bioagents not only increased seed germination, but also protected the plants from F. solani infection by acting as important elements of the cellular antioxidant system in plants upon infection, conferring the biocontrol potential of C. globosum and Trichoderma species toward mitigating the root rot disease of cumin plants in a greenhouse.

This study was conducted to investigate the effectiveness of GA3 and temperature regimes as seed priming strategies on the seed germination parameters of cumin (Cuminum cyminum L.). Cumin seeds treated with different GA3 concentrations (0, 100, 200 and 400 ppm) and then were placed in growth chamber at 20, 25, 30 and 35 °C . Some seed germination and seedling growth characters were performed for 10 days. The results showed that the percentage of germination, average duration of germination, germination speed, seedling length and seedling fresh and dry weights significantly increased along with increasing in GA3 concentration as the highest amount was found in 400 ppm. These parameters slightly increased with increasing temperature from 20 °C to 25 °C and then slightly decreased. Overall, the results suggested that the 400 ppm of GA3 in combination with 25 °C , which showed the better seed germination and seedling growth characters, could be more appropriate to use as a priming strategy in cumin seed.
