| Kidneybean(Phaseolus vlgaris L.) and buckwheat(Fagopyrum esculentum M$""{O}$nch) seedlings cultured with Hoagland solution to the height of 7 to 10cm in the earthern 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 50ppm Ca, and the other group was irrigated with Hoagland solution composed of various Ca concentrations of 0 to 1,000ppm containing 100ppm Al for a month during June and July. By Al-surplus over 100ppm, the margins of backwheat leaves were curied down and turned into yellow-brown necrosis simialr to Ca-deficiency, and the old kidney bean leaves showed marginal and veinal chlorosis in addition to the early shedding of leaves. With Al-surplus of 100ppm the content of chlorophyll a and b in both plants was decreased by 30~40%. The ratio 3/1 of chlorophyll a/b was not altered by Al-surplus and Ca-deficienty at an early stage, but it was affected markedly at a final stage of growth. Leaf respiration with 100ppm Al containing 50pm Ca was slightly affected in buckwheat, but decreased by 20% in kidneybean. With Al-surplus of 100ppm 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.trol. |
