Tomato scions (Lycopersicon esculentum Mill. cv. Hausumomotaro) were grafted on three rootstock tomato cultivars ('Achilles-M', 'Helper-M' and 'LS-89'). They were cultivated in a non-heated greenhouse from August to December under sand culture and their growth and fruit yield were compared. Tomato grafted on 'LS-89' showed the lowest plant height during growth period and days from planting to anthesis of the second and the third flower cluster were the longest among the grafted plants. Total fruit yield of the grafted tomato were almost the same, but the fruit yield of tomato grafted on 'Achilles-M' was the highers in its early growth stage and that of tomato grafted on 'LS-89' was the highest in later stage. Since the symptoms of soil infectious diseases were not observed under sand culture, we can avoid the soil infectious diseases through sand culture in tomato cultivation. It seems that the extension of tomato cultivation period may be possible under sand culture in non-heated greenhouse in central and northern China when the suitable rootstocks are selected.
