Reproduction features of organically grown edible carrot cultivars (Daucus sativus Rohl.) in Lithuania

摘要

Investigations were carried out in the organic seed-growing greenhouse at the Lithuanian Institute of Horticulture. Seed stalks of two edible carrot (Daucus sativus Rohl.) hybrids (‘Svalia’ and No 2030) and two carrot cultivars (‘Garduoles’, ‘Satrija’) were grown. Plantings of carrots’ root-crop were stored in a stationary cellar. Investigations showed that cultivar genotype and growing conditions influenced morphological characteristics of the grown carrot seeds. An abundance of the pests andtheir natural enemies were found in the seed stalks of carrot cultivars, but they didn’t differ significantly. It was established that cultivar ‘Garduoles’ is suitable for organic seed growing on organic farming. Good quality and high viability (viable - 75.0-83.0%) seeds are possible to grow in an organic seed-growing greenhouse.
