| 摘 要： | 将矮牵牛‘幻想粉红’分别培养在长日照和短日照条件下, 观测其始花期及株高、株幅、分枝数和开花数的变化; 将短日照下培养的‘幻想粉红’分别于2、4、6、8、10、12、14、16片真叶时移入长日照下进行培养, 观测从长日照处理至第1朵花开放的时间。结果分析表明: 长日照下, ‘幻想粉红’株型松散, 短日照下生长紧凑; ‘幻想粉红’为量性长日照植物, 短日照下要达到较大的营养生长量才能开花; ‘幻想粉红’的幼龄期约在8片真叶期结束。初步建议在8叶期之前采用短日照处理‘幻想粉红’,以得到紧凑的株型, 而在8叶期以后给予长日照, 以促进开花。

| Abstract: | The first flowering time,changes of plant height,crown diameter,branch number,and flower number of Petunia hybrida'Fantasy Pink'cultivated separately in long days and short days were recorded.Seedlings of petunia'Fantasy Pink'were transferred from short days to long days upon reaching 2,4,6,8,10,12,14,and 16 leaf stages respectively,the time from transfer to first flowering were measured.It is concluded that petunia'Fantasy Pink'tends to have an upright habit under long days and a compact habit under short days;petunia'Fantasy Pink'is a quantitative long day plant;it should be more vegetatively developed before flowering under short days;and the end of the juvenile phase of petunia'Fantasy Pink'is 8-leaf stage.Primary suggestion was presented that petunia'Fantasy Pink'planted under short days before 8-leaf stage to be compacted in morphology,and then under long days to be fast in flowering. |
