PRELIMINARY EVALUATION OF IODINE AND SALICYLIC ACID INTERACTION ON YIELD, FRUIT QUALITY AND IODINE UPTAKE BY TOMATO PLANTS CULTIVATED IN A HYDROPONIC SYSTEM (NFT) Sylwester Smoleń, Włodzimierz Sady, Joanna Wierzbińska Department of Soil Cultivation and Fertilization of Horticultural Plants Faculty of Horticulture, University of Agriculture in Kraków, Poland Key words: iodine, salicylic acid, biofortification, tomato, biological quality The aim of the study was to determine the influence of iodine application in two forms (I - and IO 3 - ) and salicylic acid (SA) on yield, iodine uptake by plants and fruit quality of tomato cv. ‘Rambozo F 1 ’ cultivated in a glasshouse in Nutrient Film Technique system (NFT). The following treatments were applied in the experiment: 1./ Control; 2./ 1 mg I · dm -3 nutrient solution in KI form; 3./ 1 mg I · dm -3 nutrient solution in KIO 3 form. 4./ 1 mg I (in KI form) +1 mg SA per one dm 3 of nutrient solution; 5./ 1 mg I (in KIO 3 form) +1 mg SA per one dm 3 of nutrient solution. In comparison to the control, a significant increase in iodine content in pinnate leaves and petioles from combinations 2 and 3 (the oldest – located lowermost; fully developed – first leaf above 3 rd cluster; the youngest – above 6 th cluster) was noted ranging between 780% and 8.870% for KI as well as 108% and 1.830% for KIO 3 . Additional application of SA to nutrient solution increased iodine accumulation in tested parts of plants, particularly for KIO 3 (in the range of 47% to 539%) rather than KI application (1- 25%) as well as for a greater degree in the youngest leaves than the oldest ones. Introduction of iodine salts as well its simultaneous application with SA improved iodine accumulation in fruits. Addition of SA to nutrient solution contributed to an increase in the level of phenolic compounds and acidity of tomato fruits. It was revealed that tested factors had no significant influence on yield as well as the content of lycopene and β- carotene in fruits. This work was financed by the Polish Ministry of Science and Higher Education - grant no. N N310 080238 „Effectiveness of iodine biofortification of tomato cultivated in hydroponic system with recirculating nutrient solution”.
INFLUENCE OF PUTRESCINE APPLICATION ON CROP TOLERANCE TO HEAVY METAL STRESS Petr Soudek, Marina Ursu, Šárka Petrová, Tomáš Vaněk Laboratory of Plant Biotechnologies, Joint Laboratory of IEB AS CR, v.v.i. and RICP, v.v.i., Rozvojová 263, 165 02 Prague 6 – Lysolaje, Czech Republic, e-mail: soudek@ueb.cas.cz Nowadays, there are two major problems in crop growing – pollution and nutrition. During an industrial period numerous areas were heavily contaminated by heavy metals and they are still not suitable for food production. The consumption of contaminated food crops is posing health risk for humankind. On the other hand, low concentrations of some heavy metals are essential for living organisms. The population growth puts a strong pressure on quantity and quality of substantial food. The improvement of food nutrition by the increase of essential elements concentrations in food is one of the goals. The problem is that heavy metals generate free radicals in plant cells. Plants have many types of defense mechanisms that protect them against damage by reactive oxygen. These mechanisms comprise of different types of non-enzymatic compounds such as ascorbic acid, glutathione, carotenoids, α-tocopherol, and enzymatic compounds such as APOX, GR, SOD, and CAT. Recently, many authors suggest the possible antioxidant role of polyamines as radical scavengers. For example, spermine is known for the plant tissues protection of the metal-induced oxidative damage. The aim of this work was to affect the accumulation and the translocation of toxic metals and essential elements in crop plants by external application of putrescine.
