Abstract
The present study was conducted to determine the effects of gibberellic acid (GA), alpha-tocopherol (Vitamin E) and ascorbic acid (Vitamin C) on germination in maize seeds. The s eeds w ere s ubjected t o p riming w ith 2 50 p pm GA, 3 00 ppm alpha-tocopherol, 100 ppm ascorbic acid for 24 h. The seeds which has grown at 25°C a nd 6 0 % mousture, germination rate, germination duration, germination speed, germination index, length of radicle and plumula, fresh and dry weight, relative water content, protein content and catalase enzyme activity were determined after 7 days. The results clearly revealed that GA application has an positive effects on the physiological and biochemical parameters in maize seeds. Otherwise, Vitamin E has a positive effect on germination whereas Vitamin C has a negative effects depending on the application dose. The results of GA and E applications were significiant but others were not.
