- 摘要:
- 以西瓜为试材，采用0.1% 氯吡脲开花当天喷施瓜胎的方法，研究了不同浓度（6、8、10、12、14、16、18 mg?kg-1）氯吡脲处理对西瓜果实发育、品质和产量的影响,以期为氯吡脲更好的应用于生产提供参考依据。结果表明：氯吡脲处理与对照相比，前7 d表现出瓜胎发育缓慢的现象，可促进西瓜坐果，平均坐果率提高6.8%，果皮厚度平均增加11.1%，西瓜可溶性固形物含量平均提高4.7%，增加了果皮硬度和瓜皮韧性，对产量无明显影响，处理浓度较高时，还会发生畸形果和裂果情况。通过综合比较，12 mg?kg-1 0.1%氯吡脲处理表现最好，其膨瓜速度较快，坐果率最高，达到97.4%，中心糖和边糖最高，分别比对照提高了10.3%和10.9%，产量比对照提高5.8%，果皮硬度和韧性均比对照有提高，畸形果和裂果少，可以在西瓜生产中进行推广应用。
- Abstract:
- Watermelon was used as experimental material to study the effects of different concentrations of forchlorfenuron (6，8，10，12，14，16，18 mg?kg-1) on fruit development，quality and yield of watermelon,in order to provide reference for the better application of forchlorferuron in production.The results showed that compared with the control，forchlorferuron treatment showed a slow development of melon embryo in the first 7 days，which could promote watermelon fruit setting，with an average fruit setting rate increased by 6.8%，an average increase of peel thickness of 11.1%，and an average increase of soluble solid content of 4.7%.It increased peel hardness and peel toughness，and had no significant effect on yield.When the treatment concentration was high，it would also cause abnormal fruit and fruit cracking.Through comprehensive comparison，the treatment of 12 mg?kg-1 0.1% forchlorferuron showed the best performance，its expansion speed was faster，the fruit setting rate was the highest，up to 97.4%，the central sugar and edge sugar were the highest，which were 10.3% and 10.9% higher than the control respectively，and the yield was 5.8% higher than the control.The peel hardness and toughness were higher than the control，and there were fewer deformed and cracked fruits.It could be applied in watermelon production.
