| 摘 要： | 对不同苗龄植株短日诱导后花芽分化和开花进程进行观察及切花品质指标测定,研究苗龄对切花菊品种精云花芽分化及切花品质的影响。结果表明:苗龄对切花菊精云花芽分化与品质有显著影响。苗龄越短花芽创始越迟,苗龄为0 d(定植当天短日处理)的植株从成花诱导到花芽创始需18 d,显著长于苗龄为28 d或以上植株成花诱导所需的4 d。苗龄越短,完成花芽分化所需的时间越长、花期越迟、切花品质越差。4 d是精云对成花诱导的最短反应时间,28 d是达到成熟的成花感受态的苗龄,但要获得高品质切花,苗龄要达到35 d以上才能进行成花诱导。

| Abstract: | Effects of cutting age on short day induced flower bud differentiation and flower quality of cut chrysanthemum Seiun (Chrysanthemum morifolium Tzvel.) were studied.Flower bud differentiation,flowering process and flower quality were investigated in short day treated cuttings which were at different ages by modulating cutting and planting date.The results showed that cutting age was vital for flower bud differentiation and flower quality.The younger a cutting age was,the later the flower bud initiated.
