Tyrimų tikslas: Ištirti pomidorų vaisių morfologinius ir biocheminius parametrus, remiantis gautais rezultatais atrinkti veisles ar linijas, išsiskiriančias atskirais požymiais, ir jas panaudoti tolesniuose kryžminimuose siekiant sukurti išskirtinės kokybės hibridus, kurie galėtų būtų naudojami kaip funkcionalusis maistas. / The aim of the research was to investigate the tomato varieties and lines to evaluate fruit morphological characteristics and biochemical parameters and on the basis of obtained results to choose varieties and lines with the best individual features and use them in the future breeding in order to create a hybrids of exceptional quality that could be used as a functional food.

The aim of this work was to investigate the effect of fertilizers on chemical composition of raw pumpkins and quality of processed pumpkin products. The material consisted of two Cucurbita maxima 'Stofuntovaja' and 'Bambino' pumpkins cultivar. Pumpkins were grown at the organic pomological garden of the Lithuanian Agricultural University in 2004-2005. The fertilization treatment was: organic-humatic - 30 l ha-1, complex fertilizers (10:10:20 - 500 kg ha-1, compost (mixture of composted manure 70% and plant waste 40%) - 40 t ha-1, complex + organic-humatic fertilizers - 500 kg ha-1 + 30 l ha-1. Biochemical composition and quality of processed pumpkins products (jams, bread and wine) was analyzed. It was determinate better biochemical composition in raw pumpkins grown with complex + organic-humatic fertilizers. Better sensual characteristics had products processed from pumpkins grown with organic-humatic fertilizers.
