摘　　要：以不同熟性的青花菜品种(早熟品种中青10号、中早熟品种中青9号、中熟品种中青8号)为试材,采用不同低温处理对幼苗进行春化诱导,研究不同低温积累强度对青花菜生长发育、产量和品质的影响。结果表明:青花菜春化处理最适温度为15℃。与对照相比,低温处理能显著加快春化进程,且温度越低青花菜生育期越提前,主花球结球节位越低,但花球品质和产量却显著下降;反之,温度越高,青花菜的生育期延后,但花球产量和品质有所提高。Three broccoli(Brassica oleracea L.var.italica Plenck)cultivars,including earlymaturity‘Zhongqing No.10’,mid-early maturity‘Zhongqing No.9’and medium maturity‘ZhongqingNo.8’were taken as experimental material and treated with different low temperature for vernalisation to explorethe effects of different low-temperature accumulation intensity on broccoli growth,development,yield andquality.The results showed that the optimum temperature for broccoli vernalisation is15℃.Compared with thecontrol,low temperature treatment could significantly facilitate the vernalisation process and the lower temperatureis,the shorter growth duration,and the lower the node order of the main ball-flower is,but the yield and qualityof broccoli were reduced significantly.On the contrary,the higher temperature is,the longer growth durationis,while the yield and quality of broccoli were improved.
