연구논문 : NaCl 스트레스에 의한 Brassica속의 발아 및 유묘기 생장 반응

Experiment was carried out to observe seed germination and seedling growth of Brassica species such as cabbage (Brassica oleracea capitata L.), cauliflower (Brassica oleracea botrytis L.) and canola (Brassica napus) in four treatments of salinity including 0.0 (control), 0.5, 0.8 and 1.0% NaCl. The results showed that different concentration of salinity had considerable effects on the germination, germination rate and root and shoot length of canola, cabbage and cauliflower. Germination percentage in all three species showed significant decrease with increasing salinity up to 1.0% NaCl. This decrease was more in cabbage as compared to canola and cauliflower. The required time for germination increased with high levels of salinity. The seedling growth of three plant species was also strongly inhibited by all salinity concentrations. Particularly at 1.0% NaCl, no measurable length was observed in all plant species. At 0.5% and 0.8% NaCl root growth of all three plant species were more affected then shoot growth by salinity. However this decrease was more prominent in cauliflower as compared to canola and cabbage.
