In a recent study conducted by Sharma, Shukla, and Gupta (2023), the researchers investigated the impact of various bioagents, including Trichoderma harzianum, T. viride, T. virens, Pseudomonas fluorescens, Bacillus subtilis, on seed mycoflora, seed germination, root/shoot length, and seedling vigor of cucumber variety Solan Srijan under controlled laboratory conditions. The study aimed to understand the potential benefits of these bioagents on the overall growth and health of cucumber plants. In addition, the seed mycoflora, specifically Alternaria sp., Aspergillus sp., and Fusarium spp., were present in the cucumber seeds, potentially affecting the growth and development of the plants.
The results demonstrated that among the bioagents tested, T. harzianum exhibited the most significant inhibitory effect on Alternaria sp. and Fusarium spp. At the same time, T. viride was most effective against Aspergillus sp. These findings indicate that using these specific bioagents could potentially help control harmful seed mycoflora, thus promoting healthier growth and development of cucumber plants.
Furthermore, the researchers treated cucumber var. Solan Srijan seeds with different bioagents and observed their impact on seed germination, root and shoot length, and seedling vigor. It was found that T. harzianum proved to be the most effective bioagent, resulting in a higher seed germination rate of 88.75%, an increased root length of 13.58 cm, and an improved shoot length of 14.58 cm. In addition, seedling vigor was substantially enhanced, reaching a value of 2501.31.
In conclusion, the study by Sharma, Shukla, and Gupta (2023) provides valuable insights into the potential advantages of using bioagents such as Trichoderma harzianum and T. viride for the treatment of cucumber seeds, as they can effectively inhibit the growth of harmful seed mycoflora and promote healthier plant development—specifically, the application of T. harzianum on cucumber var. Solan Srijan seeds were highly beneficial, leading to improved seed germination, root and shoot growth, and overall seedling vigor. This study highlights the potential of these bioagents as an eco-friendly and sustainable method to improve crop production and quality.
