Özet
The purpose of this study is to determine ratio of plants remained alive after cold temperature treatments. In order to do this, only a single cultivar from each of the 7 species of the Brassicaceae family (B.oleracea var. capitata f. alba, Brassica oleracea var. italic, Brassica oleracea var. gemmifera, Brassica oleracea var. botrytis, Brassica oleracea var. gongylodes, Brassica rapa, Raphanus sativus) has been chosen. Seedlings of these species rised for the study were separated into 4 groups and transferred to cold treatment cabinets for low temperature treatments (control, -4, -8 and -12 degrees C). Every treatment group included 10 plants. So in one replication there were 28 parcels. In the whole experimental layout numbers of parcels were 112, with four replication. After cold treatments, the number of plants remained alive were determined. Species can be ordered in a declining manner, being the first most hardy: radish, turnip, cauliflower, kohlrabi, broccoli, Brussels sprout and white-head cabbage. It is stated that radish which was found to have the highest viability ratio, is on the top of the list, white-head cabbage had the lowest ratio. Viability ratios of all he species taken into the -4 degrees C treatment were over 50%, but at remaining -8 degrees C and -12 degrees C treatments, the ratios dropped far below 50%.
