Abstract

According to the minimum seed certification standards in India, certified green gram seeds must have a germination percentage exceeding 80%. The process of storing and transporting these seeds can expose them to elevated humidity and fluctuations in temperature. These conditions may ultimately result in reduced seed viability and vigor. The utilization of priming technology has demonstrated its efficacy in counteracting the harmful consequences of seed deterioration. This technology enhances seedling strength, seedling length, and seedling dry weight. Consequently, the establishment of a standardized priming technique becomes crucial to mitigate the impact of seed deterioration caused by natural aging or variable storage conditions. In this particular investigation, two varieties of green gram, namely Kanika and Vasudha, were initially subjected to an accelerated aging experiment. Subsequently, these seeds were treated with different chemicals such as gibberellic acid, polyethylene glycol, and naphthalene acetic acid. The study aimed to evaluate the effects of various priming treatments on seed germination, vigor, and biochemical characteristics. The accelerated aging process led to a decline in germination percentage, as well as vigor indices I and II for both varieties. However, the application of distinct priming treatments was observed to substantially enhance germination percentage, seedling dry weight, and vigor indices I and II in the seeds that underwent accelerated aging. Notably, seeds primed with GA3 and polyethylene glycol exhibited particularly promising results in enhancing seed germination for both the Kanika and Vasudha varieties.
