摘    要:[目的]探讨光照处理对晚花波斯菊开花及观赏性的影响。[方法]采用随机区组设计。每天光照时间设81、01、2 h 3个水平,光照天数设7、142、1 d 3个水平,自然光照处理为对照,研究光照处理对晚花波斯菊观赏性的影响。[结果]波斯菊的观赏性以株高50 cm左右,分枝适中,株冠均匀丰满,植株开花数较多,花朵大为好。光照处理能显著影响晚花波斯菊的开花时间和观赏性状。光照天数和每天光照时间之间存在互作。光照时间处理中,以10 h光照处理植株开花最早,单株开花数最多。随着光照处理天数的增加,从播种到现蕾、开花的时间逐渐缩短。光照天数处理中,以每天处理10 h,处理21 d最好。[结论]处理14 d,每天10 h光照时,晚花型波斯菊的观赏性最好。

关 键 词:光照处理  晚花波斯菊  观赏性

Abstract:[Objective] The study was to explore the effects of light treatment on flowering and ornamentals of late flowering calliopsis.[Method] In test with the randomized block design,the effect of light treatment on ornamentals of late flowering calliopsis was studied by setting up 3 illumination times(8,10,12 h) per day and 3 illumination days(7,14,21 d) and with the natural illumination treatment as CK.[Result] The ornamentals of calliopsis was nice when its plant height was about 50 cm with moderate branch,was uniform and plump of canopy,more flowers and big flowers per plant.The flowering time and the ornamental character of the late flowering calliopsis could be significantly affected by the treatment of illumination.The interaction existed between the illumination days and the illumination times of per day.,When the treatment of illumination time was 10 h in the illumination time treatments,the plant bloomed earliest and the number of the flowers per plant were the most.The time from sowing to bud and flowering was gradually shortened with the increasing of the light treatment days.It was the best of being treated 21 d and 10 h per day in the treatments of illumination days.[Conclusion] The ornamentals of late flowering calliopsis was the best when the illumination was treated as 14 d,and 10 h per day.
Keywords:Light treatment  Later flowering calliopsis  Ornamentals
