摘要/Abstract

摘要： 将3年生‘大富贵’芍药于2003年11月5日用不同浓度的赤霉素(GA₃ ) 和生根粉(ABT)喷淋根部后上盆, 置背阴处直至2004年2月5日移入温室促成栽培, 于4月2～22日先后开花。调查结果表明, GA₃与ABT组合处理, (1) 明显促进花芽集中萌发, 其中GA₃ 150 mg/L的处理萌发期仅2～3 d,而对照为8 d; (2) 明显促进开花, 使开花期比对照提前约10 d, 但开花分散, 群体花期比对照延长约1倍; (3) 提高成花率20%以上, 其中单纯用GA₃150 mg/L处理时成花率最高(93% ) , 但花径、株高、叶幅等却下降, 切花质量均不如其它处理; (4) ABT促进新根形成与生长, 对提高切花质量有一定作用, 其中ABT 100 mg/L + GA₃ 100 mg/L处理效果较好。

Abstract: Three-year-old plants of Paeonia lactiflora ‘Da Fugui’were potted after being sprayed with the different concentration combinations of gibberellin (GA₃ ) and rooting power (ABT) solution on Nov. 5 of 2003, kept in the shade until forced in a greenhouse on Feb. 5, 2004, and flowered during Ap r. 2 - 22. The results showed that the combination of GA₃ and ABT (1) Promoted the sprouting of flower buds uniformly, of which 150 mg/L GA₃ made the plants finishing sprouting in 2 - 3 days thatwasmuch less than 8 days in the control; (2) Significantly promoted flowering thatwas earlier about 10 days than in the control, but inflorescence of the population was prolonged one-fold with dispersed flowering; ( 3) Flowering rate was increased 20% and the highest was 93% in the treatment using 150 mg/L GA₃ alone, but the quality of cut-flower was totally better in 100 mg/L GA₃ ; (4) ABT promoted new-root formation and growth and had a positive effect in improving cut-flower quality. The treatment of combinated 100 mg/L GA₃ and 100 mg/L ABT had better comprehensive result for forcing culture.
