Seed viability of maize (Zea mays L.) declines at a rapid pace. Maize being an important crop, considered worldwide, any measure effective for its seed potentiation is considered to be of worth. Experimentation with sodium dikegulac (Na-DK) and maleic hydrazide (MH) showed here that pretreatment of maize seeds with either these two chemicals for 8 hours slowed down the aging induced rapid loss of germination. Moreover, such treated seeds showed better performance in terms of percentage of germination, field emergence capacity, fresh weight and dry weight of whole plants, root length shoot length, in comparison to the age accelerated seeds, however devoid of any treatment with sodium dikegulac (Na-DK) and maleic hydrazide (MH) and are considered as control in the experiment. Plants raised from the seeds treated with Na-DK and MH also excelled in having greater amount of DNA, RNA, chlorophyll and protein as well as higher catalase activity and lower amylase activity in comparison to the plants from control samples. Present study thus reveals the positive impact of Na-DK and MH on storage potential of maize seeds. Among two growth regulators sodium dikegulac has been noticed to be more effective in invigorating maize seeds.
