Assessment of Germination Indexes and Enzyme activity of prepared corn (Zea mays) by Salicylhydroxamic acid (SHAM) and Pyridoxine
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 4
Abstract
This study was conducted for studying the effect of seed priming of corn seed (Zea mays) by pyridoxine and salicylhydroxamic acid (SHAM) on germination and development characteristics as factorial design completely. Factors include pyridoxine with densities (witness), 0.02, 0.04 and 0.06 percent and SHAM was 0, 25 and 50 ppm. Germinated seeds were counted daily for eight days. Then fallowing items were measured: percent of germination, the length of the shoot, root and the weight of dry plant and also the amount of catalase and peroxidase activity. The results showed that pyridoxine and SHAM affects on the percent of germination, the weight of dry plant, the length of the shoot and the root and the amount of catalase and peroxidase enzyme activity on the level of one percent (p>0/01) meaningfully. However, seed priming salicylhydroxamic acid led to increase of germination indexes and the reduction of the respective enzymes' activity such as peroxidase and catalase probably caused by the neutralization of free radicals. To sum up, the results showed that pre treatment seed by the pyridoxine with 0.06 percent an SHAM with 50 ppm had the best impact on germination indexes which can help the farmers in setting and producing suitable corn plant.
