Abstract

Muskmelonplants were grown in sand culture and fertilized with a complete nutrient solution containing 0. 5, 30 and 60 ppm Mn, and 1. 33, 4.00 and 12.00 mM Ca ; 30 and 60 ppm Mn, and 1, 30 and 60 ppm Fe, in addition to control, 0.5 ppm Mn and 1 ppm Fe.In the experiment of Mn and Ca : Mn in the plant parts was significantly increased as Mn concentrations were raised from 0.5 to 60 ppm, while inversely decreased as Ca concentrations were raised from 1.33 to 12.00 mM.The fresh weight, soluble solids and scores of external fruit appearance were significantly decreased with increasing Mn levels, and were not improved with increasing Ca levels.No fruits with cracking at the blossom-end were found at 0.5 and 30 ppm Mn regardless of Ca levels, while they were found at 60 ppm Mn with 1.33 and 4.00 mM Ca.In the experiment of Mn and Fe : Mn in the plant was significantly increased with increasing Mn levels, while inversely decreased with increasing Fe levels.The fresh weight, soluble solids and scores of external appearance of the fruits decreased at 60 ppm Mn, and those receiving 30 ppm Mn were significantly decreased with increasing Fe levels.No cracked fruits were found at 30 ppm Mn, while they were found at 60 ppm Mn regardless of Fe levels.
