EFFECT OF TEMPERATURE ON FLOWER-BUD INDUCTION OF LONGAN IN PHYTOTRON

Q.X. Chen, D.M. Pan, L.X. Lu
The phytotron was used to investigate the effect of temperature on flower-bud induction of longan. The results showed that flower bud differentiation was induced at 6-15°C for 30 d and then 9-18°C for 80 d. However, there were no flower buds at 10-20°C for 30 d and then 15-25°C for 80 d. The suitable content of soil moisture was 14-18%; there were no flower bud under 10%. It was indicated that suitable low temperature (6-15°C, daily average temperature 9.75°C for 30 d) and the amount of accumulated lower temperature (≤6°C for 125 h or ≤10°C for 812 h, or daily average temperature ≤10°C for 21 d) were the key factors of flower bud differentiation in logan.
