칼륨수준이 수경토마토의 영양생장과 과실수량에 미치는 영향 = Effect of Potassium Level on Vegetative Growth and Fruit Yield of Hydroponically Grown tomato Plants

다국어 초록 (Multilingual Abstract)

Tomato (Lycopersicon esculentum MILL.cv. Ogatazuiko) plants were grown is the nutrient solution at five levels of potassium (1-16me/l) which were adjusted by addition of K₂SO₄. Leaf and stemgrowth at 1me K was largly restricted and K deficiency symptoms was observed. However, there were no significant differences in vegetative growth in the rang 2-16me K.K content of the leaves increased with the increment of K in the nutrient solution but there was no significant differences in N content of the leaves.
The result obtained here demonstrated that 4-16me K is thought to be suitable for stabilized fruit production.
