摘要(Abstract)：
以草莓品种丰香、吐德拉、全明星、北辉为试材,研究了移栽时期、生根方式对草莓微繁殖苗移栽后开花结果的影响。草莓微繁殖苗在春季移栽时期对开花结果习性具有重要影响,2月份移栽,4个品种都开花结果,成熟期比露地栽培草莓大约晚20d,全明星、吐德拉和丰香3个品种的产量与普通苗露地栽培的产量相近;3月份移栽,虽然有开花结果,但并无经济学产量;4月份移栽,4个品种均未开花。不同品种的微繁殖苗在开花株率、单株产量等指标上差异显著,其中全明星微繁殖苗的开花结果能力最强,2月份移栽的微繁殖苗的开花株率达89.3%,单株产量达98.2g。在花序数上,培养基中不含植物生长调节剂处理显著高于附加植物生长调节剂的处理。
