AbstractAbstract
[en] Since its beginnings, the Agricultural Area had a selected research team involved in the development of different agricultural techniques. Currently, there are two main branches engaged in the solution of agricultural problems: Soil fertility and induced mutations. Soil fertility: Within this branch, studies on soil nutrients and availability of water and light resources, have been made by using isotope methods. In the near future studies on nitrogen and potassium content in potato, rice and wheat plantations will be held. Induced mutations: The main objective of this team is to obtain through radioinduced mutations, as well as in vitro growth, improved rice and other cereal seeds to be used under hostile environmental conditions. The further goal will be to develop new genotypes straight from the mutants or by utilization of this material as breeding materials in interchange programs

AbstractAbstract
[en] Potato tubers Solatum tuberosum L. cv. Alpha were irradiated with 0.12 kgy and stored at room temperature. The endogenous hormones were extracted and determined using bioassay at dormant, budding and sprouting stages. The studied promoters were IAA, IAN, GA3 and Gibberellin like substances besides the inhibitors which included ABA and B-inhibitors. The results indicated that IAA was more sensitive to irradiation than IAN, GA3 but ABA was more stable than B-inhibitors during the dormancy. Irradiation decreased IAA and Gibberellin like substances and B-inhibitors but no change was observed in ABA content at dormant period. Irradiation caused a balance between promoters inhibitors at the end of tuber storage and after tubers sprouting
