抄録

Grafted tomato (scion : Lycoperisicon esculentum Mill. cv. Momotaro ; rootstock : cv. Helper M) plug seedlings were stored at 10°C for 21 d under photosynthetic photon flux density (PPFD) of 2μmol m^-2s^-1 using mixed light from red and blue light LEDs, with different red/ blue PPFD ratios (100/0: R100, 97/3 : R97B3 and 50/50: R50B50) . The stored seedlings were transplanted and cultivated for 14 d at 25/18°C (day/night) and 300μmol m^-2s^-1 PPFD. The seedlings in R100 tended to lose their dry weight (DW) during storage, while those in R97B3 and R50B50 did not. On the last day of the storage, the contents of ribulose-1, 5-bisphosphate carboxylase/oxygenase (Rubisco) and chlorophyll tended to be greater with decreasing the red/ blue PPFD ratio. However, there was no difference in DW of tomato plants at the last day of cultivation among the treatments. These results indicated that the difference in the contents of Rubisco and chlorophyll caused by different red/blue PPFD ratios did not affect the growth during cultivation following the storage. On the last day of the storage, the contents of carbohydrate were extremely small in all stored seedlings irrespective of the red/blue PPFD ratios. They may lead to no difference in the growth of tomato plant during cultivation following the storage. However, blue light mixing both in R97B3 and R50B50 was effective for maintaining DW and the visual quality due to the greater chlorophyll content during the low temperature storage of grafted tomato seedlings.
