【摘要】 采用了田间和室内相结合,固定植株跟踪观察的方法,对海巴戟(Noni)开花习性与授粉方式进行了观察研究。结果表明:海巴戟在海南周年开花,开花的数量和质量一年四季有所不同,开花盛期为每年的4～7月。每朵花从开放到凋谢的时间平均2d,开花高峰期在每天清晨9～10h,下午也有开花,授粉后花瓣掉落。单花序从初花至尾花开放持续时间平均42d,平均开花数20朵,海巴戟授粉方式为自花授粉。文中就双受精对海巴戟果实膨大的影响,花器结构对授粉方式的影响等展开了讨论。更多还原

【Abstract】 Purpose: Studying the Noni flowering habits and pollination methods.Methods: Adopting the combination of field and indoor use,fixed plant tracking observation to observe the Noni flowering habits and pollination methods.Results: The Noni in Hainan can bloom all year round,but the quantity and quality of flowering vary throughout the year,flower stage in July each year.The average time of a flower from opening to withering are 2 days.The peak flowering period of a day is during the early morning 9 to 10,there are also flowering in the afternoon,and the petals fall after pollination.The average time of the inflorescence from the first flower to the end of flower opening are 40 days,the average number are 20 flowers and the pollination method is the self-pollination.The paper also discussing the double fertilization on the impact of the enlargement of the Noni fruit and the flower structure on the impact of the mode of pollination.更多还原
