摘 要: | [目的]研究切花菊的光周期和花期调控。[方法]比较了广州地区常见的21个切花菊品种(11个小菊品种和10个大菊品种)光周期反应。[结果]根据短日照至开花的周数(即光周期敏感性),切花小菊品种可分为6~10周菊;大菊品种可分为9~12周菊类。为达到切花菊的标准株高,推算不同品种秋冬季长日照灯控处理的天数在14~66 d不等。[结论]为广州地区切花菊的花期调控和延迟栽培提供了理论依据。

Abstract: | [Objective] The aim was to study the photoperiod and flowering regulation of 21 cut chrysanthemum cultivars.[Method] Photoperiod reactions of 21 cut chrysanthemum cultivars including 11 small-flowered and 10 large-flowered cultivars were observed throughout whole growth cycles in Guangzhou.[Result] According to weeks of short daylengthes(sensitivity of photoperiod),the small-flowered cultivars were divided into 6 to 10-week groups,and the large-flowered cultivars were divided into 9 to 12-week groups.In order to get the harvest standard length of cut flowers,the light-controlled long daylengthes of specific cultivars were respectively speculated from 14 to 16 days in autumn and winter.[Conclusion] The research provides theoretical basis for flowering regulation and delay-cultivation of cut chrysanthemum. |
