| Abstract:
Tomato (Lycopersicon esculentum Mill) plants cv. ‘OHGATAFUKUJYU’ and ‘MOMOTARO’ were cultured in nutrient solution of varying sulfate concentration. We found a decrease in crease-stem abnormality with high sulfate nutrient solution in both varieties. The effect of high sulfate solution on the decrease of stem abnormality was more remarkable in ‘OHGATAFUKUJYU’ than in 'MOMOTARO'. There was a tendency of decrease in phosphorous, potassium, calcium and magnesium content in the stem of tomato plants in these conditions. Boron content in the stem of tomato grown in high sulfate solution was higher than that of one grown in low sulfate. It is suggested that boron inhibits the occurrence of the crease-stem abnormality, though the effect of sulfate on inhibition of this disorder is still not clear. | |
