- Fe deficient chlorosis in the leaves of greenhouse roses induced by excess phosphorus in soil.
説明
Recently chlorosis in leaves is frequently appeared in the greenhouse roses, and it depreciates rose cut flowers.<BR>In this paper, the relationship between the appearance of chlorosis and soil chemical properties, some mineral contents in plant leaves was investigated. The results obtained were as follows.<BR>1. The exchangeable CaO, MgO, K2O and Mn were respectively contained in the ranges of 133-294 mg, 24.8-53.9 mg, 24.3-89.4 mg/100 g soil and 0.8-9.7 ppm in the cultivated soil of the greenhouses.<BR>2. The concentration of extractable Fe was markedly low in a range of 2.3-5.2 ppm. On the contrary, available phosphorus indicated by Truog P was in a range of 144-332 mg/100 g soil and it was extremely abundant.<BR>3. Correlation between the appearance of chlorosis and mineral contents in tested soil was not recognized.<BR>4. The phosphorus content and chlorophyll in rose leaves showed a negative correlation at 1% level of significance.<BR>5. It became clear from this investigation that the appearance of chlorosis was dependent on Fe deficiency induced by excess phosphorus in rose leaves and Fe deficient chlorosis was assumed to appear when phosphorus concentration in leaves was higher than 0.45%.
