- Abstract:
- The temperature and light are key environment factors for the healing of grafted seedlings.The healing period of grafted watermelon seedling can be divided into three stages (0-3 d，4-6 d，7-8 d)，the precise management of temperature and light during healing period is not clear.With‘Zaojia 84-24’as watermelon scion as test materials，two high affinity grafting of calabash and pumpking as stock，the effect of two temperature and three light intensity combination treatments during the healing period on the growth of grafted watermelon seedlings was investigated.The results showed that when the temperature treatment was 28℃/23℃（0-3 d），25℃/20℃（4-6 d），23℃/18℃（7-8 d），and the light intensity treatment was 75 μmol?m-2?s-1（0-3 d），150 μmol?m-2?s-1（4-6 d），225 μmol?m-2?s-1（7-8 d）after grafting，the grafted watermelon seedlings showed the highest survival rate and the best seedling quality，indicating that this kind of temperature and light combination was suitable for healing management of grafted watermelon seedlings.
