Abstract

Dynamics of onion seeds germination with different germinability and magnetic field influence with variable intensity on onion germinative activity was determined in trials. Amika F1 hybrid marked low germinative activity. On 21th day after trial foundation it reached germinability of 34–46%. Halftime of this germination was reached on fourth to fifth day after trial foundation. Exhibition variety had convenient germination activity, 70–91%. Halftime of its germinability was reached on sixth to eighth day after trial foundation. On the base of submitted results there can be said that the seed with low germinative activity has faster initial start of germination. The seed with suitable germinative activity has more regular course of germinability from the beginning till the end of germination. Seeds of varieties Amika F1 and Exhibition achieved significantly lower germination in the radiation intensity of 20 mT compared to other variants with the radiation intensity of 40 mT, 55 mT and the control one. Between the variants of 40 mT, 55 mT and the control one the differences were not significant.

Abstract

Carrot (Daucus carota L.) belongs to the most common type of vegetable because of its consumption, versatile usage in the canning industry and because of its beneficial effects on the health of consumers. It is valuable mainly because of the high content of β-carotene, B vitamins, vitamin C, carbohydrates and minerals. The aim of this work was to compare the quality of carrot juice from different varieties of carrots regarding the content of total carotenoids and polyphenols and also to assess the dynamics of their changes evaluated under the influence of the pasteurization (85 °C). There were selected varieties of carrot such as Baltimore F1, Exhibition F1, Kamaran F1, Napoli F1, Belgrado F1, Komarno F1, Nantes, Rubina and Nandrin F1. The highest content of carotenoids, assessed by the spectrophotometry, was determined in variety Kamaran F1 (213.66 mg 100 g−1 dry matter) and the lowest in Belgrado F1 (146.80 mg 100 g−1 dry matter). After the pasteurization, the content of carotenoid decreased and ranged from 128.04 mg 100 g−1 dry matter in variety Napoli F1 to 142.55 mg 100 g−1 in Kamaran F1. The highest content of polyphenol determined by the Folin Ciocalteu method was found in fresh juice of Rubina (922.80 mg GAE 100 g−1 dry matter) and the lowest in the variety Nantes (535.75 mg GAE 100 g−1 dry matter). After the pasteurization, the content of the monitored components was found to be 450.34 mg GAE 100 g−1 dry matter in Napoli F1 to 751.95 mg GAE 100 g−1 dry matter in Komarno F1 variety.
