박권우(Kuen Woo Park),이정훈(Jeong Hun Lee),김민제(Min-Jea Kim),원재희(Jae Hee Won) (사)한국생물환경조절학회 2004 생물환경조절학회지 Vol.13 No.4
오이와 토마토의 발아에 미치는 전작물 잔유물(양배추, 무, 파, 상추)의 효과를 포트에서 시험하였다. 그 결과 파가 발아를 가장 억제 시켰으며 무, 양배추, 상추의 순이었다. 다만 오이의 경우 상추는 발아를 억제시키지 않았다. 채소잔유물의 오이, 토마토의 발아억제는 약 20일간 지속되었고 그 후에는 오히려 생육을 촉진시켰다. 촉진은 억제의 반대 순서로 파, 무, 양배추, 상추의 순이었다. 양배추, 무, 파, 상추의 추출물을 5, 10, 17, 23, 35, 50, 65%로 희석하여 오이와 토마토의 발아와 유근 신장에 미치는 시험을 실시한 바 저농도인 5, 10, 17, 23%에서는 모든 처리가 오이의 발아를 억제하지 않았다. 상추의 35, 50, 65% 처리구에서는 오이 발아가 이루어지지 않았다. 잎파는 65% 처리구에서만 오이의 발아억제현상이 보였다. 오이의 유근 신장은 다만 잎파의 경우에 저농도인 17, 23%에서 억제적이었다. 고농도에서는 양배추, 무 추출액 35%를 제외하고는 모두 오이의 유근 신장을 억제하였다. 토마토는 저농도에서는 상추만 제외하고 억제현상이 없었으나 고농도인 35, 50, 65%에서는 발아억제 현상이 뚜렷하였다. 50% 이상 구에서는 오이와 달리 전혀 발아가 되지 않았다. 유근의 신장은 토마토의 경우 파와 상추 추출물이 23%이상에서는 강하게 억제하였다. 이상의 결과로 미루어 채소류의 추출물도 오이보다 토마토의 발아 억제를 심하게 하고 고농도에서는 유근의 신장을 억제하였다. Effects of cucumber and tomato seed germination by previous leaf and root vegetables (cabbage, radish, welsh onion, lettuce) residue in soil were tested in pot condition. Overall, suppression effect of welsh onion residue was the greatest in 4 tested crop residue and followed by radish, cabbage and lettuce, but lettuce residue didn't have effect on cucumber seed germination. Suppression were maintained ca. 20 days but after the time point, growth of cucumber and tomato were enhanced. Enhancing effect of welsh onion residue was the greatest in 4 tested crops residues and followed by radish, cabbage and lettuce. As a conclusion, residue of welsh onion, radish and cabbage were suppressed the germination of cucumber and tomato seeds but enhanced growth after 20 days of treatment. To verify the effective concentration of residue on suppression of germination and growth of radicle of cucumber and tomato, plant extract of welsh onion, radish, cabbage and lettuce were diluted as 5, 10, 17, 23, 35, 50, and 65%, and then tested. In low concentration treatment, 5, 10, 17, and 23%, all 4 crop extracts didn't suppress cucumber seed germination. High concentration of lettuce extract, 35, 50, and 65%, cucumber seed didn't germinate at all. In case of welsh onion extract, only 65% treatment suppressed cucumber seed germination. In low concentration treatment, 17, and 23%, only the welsh onion extract suppressed young radicle. In case of high concentration treatment, except 35%, all four crops extract suppressed cucumber radicle growth. In low concentration treatment, tomato seed germination was suppressed by lettuce extract only but in high concentration treatment, 35, 50, and 65%, all extracts suppressed germination. Especially higher than 50% treatment, tomato seed didn't germinate at all. Radicle growth was highly suppressed in welsh onion and lettuce extract, higher than 23% concentration. As conclusion, leaf and root vegetable extracts suppressed cucumber and tomato seed germination and in high concentration, also suppressed radicle growth.

이스람모하메드조히를(Islam Mohammad Zahirul),유태종(Tae-Jong Yoo),정현진(Hyun Jin Jung),최인이(In-Lee Choi),전신재(Shin Jea Jeon),원재희(Jae Hee Won),이윤석(Youn Suk Lee),김영식(Young Shik Kim),김일섭(Il Seop Kim),강호민(Ho-Min Kang) (사)한국생물환경조절학회 2010 생물환경조절학회지 Vol.19 No.2
본 연구는 국내에서 주로 생산되고 있는 대과종 토마토 품종의 품질을 비교 조사하여, 토마토의 원활한 유통 및 수출을 위한 수확후 관리 분야의 연구의 기초 자료를 얻고자 수행되었다. 과피색은 품종별 일정한 경향 없이 a*/b 값은 2.8에서 4.8범위 안에 있었다. 호흡률과 에틸렌 발생률도 품종간 큰 차이를 보이지는 않았다. 내적 품질 중 경도는 ‘Picasso’, ‘Tymaxx’, ‘Madison’에서 가장 높았다. 당도의 경우 대체로 6°Brix 수준을 나타내었는데 ‘Hoyong’과 ‘Dotearang Dia’가 높았다. 비타민 C 함량은 ‘Super Sunroad’와 ‘Dotearang Dia’가 가장 높았다. 산도는 품종별 큰 차이 없이 ‘Hoyong’이 가장 높았으며, 이 때문에 당산비는 당도와 유사한 양상으로 유럽계 중 당도가 낮았던 ‘Amaral’, ‘Picasso’, ‘Tymaxx’에서 낮았다. 이상의 결과로 보면 수출 토마토에서 중요한 품질 요인인 경도는 유럽계가 당도와 비타민 C 함량은 동양계가 높았다. 품질 요인간 상관관계는 a*/b* 값으로 표시한 과피색이 여러 품질 요인과 높은 상관관계를 나타내었는데, 특히 당도와 가장 높은 상관계수(r = 0.801)를 나타내었다. 또한 수출현장에서 중요하게 다루는 경도와 당도는 부의 상관관계(r = ?0.601)를 나타내었다. This study was conducted to compare the quality characters of 15 different tomato cultivars (‘Dotearang Dia’, ‘Super Dotearang’, ‘Super sunroad’, ‘Hoyong’, ‘Mirokku’, ‘Baccuhs’, ‘Mascara’, ‘Poseidon’, ‘Radido’, ‘Madison’, ‘Rapsodie’, ‘Solomon’, ‘Amaral’, ‘Picasso’, ‘Tymaxx’) and find out the correlation among the quality characters in order to get basic informations for exporting tomato. The a*/b* value of fruit surface showed from 2.8 to 4.8, but there was no significant difference in fruit surface color value, such as a*, b* and a*/b* among the cultivars. The respiration and ethylene production rate also were not shown any significantly difference among cultivars. The firmness of fruit was higher in ‘Picasso’, ‘Tymaxx’ and ‘Madison’ cultivars. The contents of soluble solids was higher in ‘Hoyong’ and ‘Dotearang Dia’ cultivars. The vitamin C content was higher in ‘Super Sunroad’ and ‘Dotearang Dia’ cultivars. The titratable acidity was higher in ‘Hoyong’ cultivars. The sugar/acid ratio that depended on soluble contents was lower in ‘Amaral’, ‘Picasso’, ‘Tymaxx’ cultivars that showed lower soluble contents. Conclusionally, The firmness that was one of the most important quality character in exporting tomato was higher in European cultivars, but soluble solide and vitamin C content were higher in Japanese cultivars. The significant correlation coefficient values were determined (more than p = 0.05) between a*/b* and other quality characters. The results suggested that surface color was the most suitable character represented tomato qualities. The high coefficient value (r = 0801) between a*/b* and the contents of soluble solids. The firmness and the contents of soluble solids that is the most important factor for exporting showed significant negative correlation (r = ?0.611).

This study was conducted to compare the postharvest physiological characteristics and qualities of 5 different tomato cultivars; `Koko`, `Suncherry-250`, `Unicon`, `Aranka` and `Campri`. Tomatoes were harvested by 3 different maturities; turning (30% orange color), pink (80% orange color), and light red (30% red color) stages. The respiratory rate and ethylene production rate was higher in cherry tomato cultivars (`Koko`, `Suncherry-250`, `Unicon`) than the truss cultivars (`Aranka`, `Campri`). The firmness of fruit decreased with increase of maturity, and it was the highest in `Unicon` among cherry tomato cultivars and `Aranka` between truss tomato cultivars. As maturity increased, soluble solids increased and it was higher in cherry tomato cultivars than the truss cultivars, and the highest in `Suncherry-250` among cherry tomato cultivars. However, the titratable acidity decreased with the increase of maturity, and it was higher in `Aranka` among all cultivars. The sugar/acid ratio was lower in truss cultivars than the cherry tomato cultivars, because of titratable acidity. The vitamin C content increased as maturity progressed and it was higher in cherry tomato cultivars than the truss tomato cultivars. The firmness that should be the one of the most important quality for exporting tomato was higher in `Unicon` among cherry tomato cultivars, but there was not any significant difference in qualities between truss cultivars.
