Physiological Response of Potato Variety to Soil Salinity

Abstract

This study was conducted to examine the basis for the information to select the suitable potato varieties grown in new reclaimed land. The potatoes of five varieties were planted in the port with 4 different electrical conductivities of saturated extracts of soil taken the Saemangeum reclamation area, which was made of non-treatment salt and three concentrations of salt treatment, 1.6 dS m , respectively, and the number of its branch decreased by 14-58% comparing to non-treatment salt depending on varieties. Since the increase of the salt concentration of the soil was more serious the decrease of the number of its branch, but plant height tended to increase when branch number per plant was small, which was depending on more number of its branch than salt concentration. Fresh tuber yield of potato comparing to non-treatment salt were decrease 33.7% in 1.6 dS m

“…토양수에 함유된 Na + 이온은 Na 2 CO 3 를 형성하고 토양의 pH를 높여서, 토양내 철, 인 등의 가용성을 떨어뜨려 다양한 무기성분의 식물 체내 흡수를 방해함으로서 이들과 관련된 작물의 품질에도 영 향을 주는 것으로 알려져 있다 (Ayers and Westcot, 1985). 염 스트레스 환경에서 감자는 파종후 출현 지연, 줄기 왜화, 엽수 및 엽면적 감소, 총 엽록소 감소, 식물체 노화, 괴경 경화, 표 피 러셋화 등 생육 불량과 괴경의 형태적 품질 악화 등이 밝혀 져 있으며, 이들의 종합적인 결과로써 수량성 저하가 보고된 바 있다 (Levy and Veilleux, 2007;Kim et al, 2013;Im et al, 2016). 염스트레스 환경에서 가공 형질에 관해서는 토마 토 (Yin et al, 2010) (Flowers et al, 1977;Levy et al, 1993;Jaarsma et al, 2013).…”
