晚香玉切花花期调控

Control the Flowering Period of Tuberose

采用不同温度(低温、高温)、赤霉素处理打破种球休眠,调控晚香玉花期,达到周年生产的目的。结果表明:10月栽植的晚香玉,种球经低温和激素处理可解除休眠的抑制作用,提前花期28～40天,开花率达86%以上。高温和低温处理晚香玉种球可使11月栽植的晚香玉花期提前22天。高温处理可使12月栽植的晚香玉花期提前18天,提高开花率43%。并提出了晚香玉切花淡季生产日历,分析了不同栽植时期晚香玉切花品质的变化。

The seed balls resting were breaked up by differntial temperature(low tempereture or high temperature), gibberellin treatment. Controlling the flowering period of tuberose in order to achieve the goal of anniversary production. And productional time of slack season production was put forward and the qualitative variation of tuberose cut flower was analysed at differential planting season.
