| Title : | QUANTITATIVE AND QUALITATIVE CHARACTERISTICS OF SELECTED LETTUCE HYBRIDS (Lactuca sativa L.) IN A PROTECTED AGROSPACE |
| Abstract : | In order to solve the mentioned problem, two-factor experimental research was conducted with eight lettuce hybrids: Tonale, Donertie, Hetti, Limeria, Nolanie, Australiae, Cencibel and Saturdai. Lettuce was grown in the winter period in a protected agricultural area without a heating system, and the quantitative and qualitative component of the yield was monitored with an emphasis on the vitamin C content, and the amount of accumulated nitrates and nitrites depending on the hybrid, the technological maturity of the plant and the position of the leaf in the head. Based on the results of the analysis (ANOVA), a significant influence of the tested parameters (hybrid) on the quantitative characteristics of the plant was determined, the Hettie hybrid with a head weight of 633 g was rated as the best hybrid. Different time periods of plant development, as well as the type of hybrid, showed a statistically significant influence on the average nitrate content in the fresh mass of the plant, as well as the amount of nitrate depending on the part of the plant (outer rosette leaves, middle leaves and inner leaves), and the highest amount of nitrate recorded in all hybrids in the outer leaves of the leaf rosette and increased in relation to the extension of the plant's development time, ranging from 524,212 mg/kg hybrid Tonale to 2562,323 hybrid Hetti. In all tested hybrids, a drop in vitamin C concentration was recorded after 60 days of development. |
