Abstract

Solanum tuberosum L. (potato) is a crop in temperate regions, exhibiting exceptional food productivity and adaptability. Plant hormones can be used to increase the yields. Gibberellic Acid 4+7(GA4+7) is a plant growth regulator which can increase germination rate of some seeds and induce leaves. In this study, Potato tubers were treated with different concentration of  GA4+7 solution and another set of tubers were treated with distilled water(controlled).The different  growth parameters  such as number of sprouts, Length of seedlings, number of leaves and  Chlorophyll content was observed  after 15, 22, 29 and 36 days. The result showed that the number of sprouts of potato tubers was increased with the increasing concentration. The lengths of the potato seedling of GA4+7 treated tubers were more than the seedlings of the controlled tubers. Also, the GA4+7 treated seedlings produced more leaves and more chlorophyll content in leaves than the controlled seedlings. This result suggests that GA4+7 can induce germination of potato tubers and break the dormancy. It can enhance seedling growth by producing photosynthetically efficient leaves and finally the tuber growth takes place and ultimately the yield of potato tuber increases.
