摘要: 采用迁光的方法测定‘幻想’矮牵牛的幼龄期和限界性诱导光周期。结果分析表明: ‘幻想’
矮牵牛的幼龄期约在6片真叶期结束, 其限界性诱导光周期为3周。与连续诱导光周期相比, 限界性诱导
光周期能明显抑制‘幻想’矮牵牛株高的生长, 对株幅和分枝数无明显影响。建议在‘幻想’矮牵牛8叶
期时给予长日照处理以促进开花; 3周以后再给予短日照处理以节约能源, 同时可以控制株高。

Abstract: Juvenility and limited inductive photoperiod (LIP) of Petunia hybrida ‘Fantasy’were exam
ined by transferring plants between short days ( SD) and long days (LD). It is concluded that the end of the
juvenile phase of petunia is about 62leaf stage, and the LIP of petunia is 3 weeks. LIP inhibited stem elonga
tion of petunia compared to plants grown in continuous LD, while it did not affect crown diameter and branch
number at first flower. Suggestionswere p resented that petunia Fantasy should be p lanted under long days up
on 8-leaf stage for fast flowering, and planted under short days after 3 weeks for saving energy, and the plant
height can be shortened at the same time.

Key words: Petunia hybrida, Juvenility, Limited inductive photoperiod
