알루미늄용액 처리가 세 수종의 종자발아와 묘목생장에 미치는 영향 = Effects of Aluminum Solution Treatment on Seed Germination and Seedling Growth of Three Tree Species

다국어 초록 (Multilingual Abstract)

To examine aluminum toxicity on woody plants, aluminum solution and ground water(pH 6.75) were treated on the seeded pot (48$\times$33$\times$9cm) of Pinus thunbergiana, Thuja orientalis and Ligustrum obtusifolium, filled with sand, three times per week, 5mm per time, from April 28, 1993 to June 16. Aluminum solution were prepared 1.0, 2.5 and 5.0mM aluminum potassium sulfate, dilulted with ground water. Growth-related characters(seedling number, seedling height, top, root and total dry weight) were measured and compared among species and treatments. The response of seedling growth-related characters to aluminum solution treatment differed among the species, and the most sensitive species is Ligustrum obtusifolium, and the most tolerant species is Pinus thunbergiana.
