In the heart of Gujarat, India, a groundbreaking study is reshaping our understanding of seed quality and longevity, with significant implications for the agricultural sector. Dr. K. M. Bera, a leading researcher from the Department of Seed Science and Technology at B. A. College of Agriculture, Anand Agricultural University, has been delving into the effects of accelerated ageing on brinjal (eggplant) seeds, particularly the popular variety ‘Anand Raj’. His findings, published in the ‘International Journal of Economic Plants’ (translated as ‘International Journal of Useful Plants’), are shedding new light on how ageing impacts seed quality and vigour.
The study, conducted over two years, subjected brinjal seeds to accelerated ageing treatments at 45°C and 95-100% relative humidity for varying durations. The results were telling. Non-aged seeds (T1) showcased the highest germination rate at 96.33%, along with superior seedling growth metrics. “The non-aged seeds demonstrated exceptional vigour, with the highest seedling vigour index I and II,” Dr. Bera noted. This is a crucial finding, as seed vigour is directly linked to crop establishment and early growth, which can significantly influence yield and profitability.
As the ageing duration increased, the seed quality parameters declined. Seeds aged for just one day (T2) still showed relatively high germination (94.67%) and vigour, but the decline became more pronounced with longer ageing durations. “Ageing is an irreversible process that damages seeds, and prolonged exposure to high temperatures and humidity exacerbates this damage,” Dr. Bera explained. This insight is vital for seed producers and farmers, as it underscores the importance of proper seed storage and handling practices.
The commercial implications of this research are substantial. For seed companies, understanding the impact of ageing on seed quality can lead to improved storage protocols, ensuring that seeds retain their viability and vigour until they reach farmers. For farmers, this knowledge can translate into better crop establishment and higher yields, ultimately boosting their income. Moreover, the findings can guide seed treatment and priming techniques, enhancing seed performance under various environmental conditions.
Looking ahead, Dr. Bera’s research paves the way for further studies on seed ageing and quality maintenance. Future work could explore the molecular and genetic mechanisms underlying seed ageing, leading to the development of ageing-resistant seed varieties. Additionally, the findings could be extended to other crops, benefiting a broader range of agricultural systems.
In the dynamic world of agritech, this study serves as a reminder of the intricate factors influencing seed quality and the profound impact they can have on agricultural productivity. As Dr. Bera’s work continues to gain traction, it is poised to shape the future of seed science and technology, driving innovation and progress in the agricultural sector.
