성민웅(Min Woong Sung),양운진(Woon Jin Yang) 한국식물학회 1980 Journal of Plant Biology Vol.23 No.1

ATP contents of soybean(Glycine max Merrill) and mungbean (Phaseolus radiatus L.) seeds being germinated with Hoagland solution at 30℃ for 6 days were determined. In pregerminated seed, ATP contents in soybean and mumgbean were 11.4 and 63.0㎍/g fresh seed respectively. During germination, the highest ATP content of soybean seeds was 550% of initial content on 2nd day and that of mungbean was 480% on 1st day after germination. ATP content in cotyledon of soybean and mungbean were increased up to 4th and 1st day after germination respectively, thereafter both were decreased, but those in the root, including the hypocotyl, of both seeds were continuously increased with germination progress.

식물엽의 ATP 함량에 미치는 Pb 과잉 및 P 결핍의 영향

성민웅(Min Woong Sung),권병규(Byung Kyu Kwon) 한국식물학회 1980 Journal of Plant Biology Vol.23 No.2

Kidneybean (Phaseolus vulgaris L.) and buckwheat (Fagopyrum esculentum M¨onch) seedlings grown with Hoagland solution to a height of 7 to 10㎝ in the earthen pot containing sand were used for experimental plants. One group of the experimental plants was irrigated with Hoagland solution composed of various Pb-concentrations of 0 to 1000 ppm containing 30 ppm, and the other group was irrigated with Hoagland solution composed of various P-concentrations of 0 to 1,000 ppm containing 30 ppm Pb for a month during June and July in 1979. By Pb-surplus over 100 ppm, the margins fo buckwheat were curled down and turned into yellow-brown chlorosis, but the leaves of kidneybean were become dark-green at an early stage, and then developed chlorosis, finally shedded earlier than the control. Pb-toxicity was similar to the symptoms of P-deficiency. The ratio, 3/1 of chlorophyⅡ a/b at an early stage, was unaffected by Pb-surplus or P-deficiency, but at the later stage it was altered. ATP content with Pb-surplus of 100 ppm was decreased by 69% in kidneybean leaves and by 38% in buckwheat leaves, and it with P-deficiency was decreased by 75% in kidneybean leaves and by 43% in buckwheat leaves. In the assay of ATP content of the leaves at intervals of three hours for one day of July in the year, the rhythms of ATP level were unaffected by light or temperature although the amplitude fo the level was modified. The rhythms of Pb-surplus and P-deficiency plants were observed at the lower range of ATP content than that of control.

식물엽의 ATP 함량에 미치는 중금속 ( Al , Cd , Hg 및 Pb ) 의 영향

성민웅(Min Woong Sung),양운진(Woon Jin Yang) 한국식물학회 1979 Journal of Plant Biology Vol.22 No.4

The present study was carried out to estimate the comparative effects of hydroponic heavy metals (Al, Cd, Hg, and Pb) on ATP content in plant leaves grown with Hoagland solution under green house condition. The two plants, kidneybean (Phaseolus vulgaris L.) and buckwheat (Fagopyrum esculentum Mo¨nch), showed similar inhibitory effect of heavy metals on ATP content in order of Hg, Cd, Pb, and Al. But the overall inhibitory effect was greater in kidneybean than in buckwheat. The affinity of heavy metals, in vitro, toward the enzyme (luciferin-luciferase) is in order of Hg, Al, Cd, and Pb, similar to that toward ATP. The results showed that the inhibitory effect of heavy metals on ATP hydrolysis is mainly due to the coordination of heavy metals with enzyme than ATP.

성민웅(Min Woong Sung),권병규(Byung Kyu Kwon) 한국식물학회 1980 Journal of Plant Biology Vol.23 No.1

Kidneybean (Phaseolus vlgaris L.) and buckwheat (Fagopyrum esculentum Mo¨nch) seedlings cultured with Hoagland solution to the height of 7 to 10㎝ in the earthen pot containing sand were used for experimental plants. One group of the plants was irrigated with Hoagland solution composed of various Al concentrations of 0 to 1,000 ppm containing 50 ppm Ca, and the other group was irrigated with Hoagland solution composed of various Ca concentrations of 0 to 1,000 ppm containing 100 ppm Al for a month during June and July. By Al-surplus over 100 ppm, the margins of buckwheat leaves were curled down and turned into yellow-brown necrosis similar to Ca-deficiency, and the old kidneybean leaves showed marginal and veinal chlorosis in addition to the early shedding of leaves. With Al-surplus of 100 ppm the content of chloropyⅡ a and b in both plants was decreased by 30∼40%. The ratio 3/1 of chlorophyⅡ a/b was not alterad by Al-surplus and Ca-deficiency at an early stage, but it was affected markedly at a final stage of growth. Leaf respiration with 100 ppm Al containing 50 ppm Ca was slightly affected in buckwheat, but decreased by 20% in kidneybean. With Al-surplus of 100 ppm the ATP content was decreased by 32% in the kidneybean leaves and by 80% in buckwheat leaves, whereas with Ca-deficiency it was decreased by 72% in kidneybean and by 90% in buckwheat. the rhythm of ATP level showed self-relience without being affected by light or temperature under the green house condition although by Al-s rplus and Ca-deficiency the ATP level of the rhythm was lower than that of control.

양운진,성민웅 경상대학교 축산진흥연구소 1980 畜産振興硏究所報 Vol.7 No.1

The present study was carried out to estimate the comparative effects of hydroponic heavy metals (Al, Cd, Hg and Pb) on ATP content in plant leaves grown with Hoagland solution under green house condition. The two plants, kidneybean (Phaseolus vulgaris L.) and buckwheat (Fagopyrum esculentum Mo¨nch), showed similar inhibitory effect of heavy metals on ATP content in order of Hg, Cd, Pb and AI. But the overall inhibitory effect was greater in kidneybean than in buckwheat. The affinity of heavy metals, in vitro, toward th.. enzyme(luciferin.luciferase) is in order of Hg, Al, Cd and Pb, similar to that toward ATP. The results showed that the inhibitory effect of heavy metals on ATP hydroysis is mainiy due to the coordination of heavynetals with enzyme than ATP.
