摘  要:
研究了不同浓度易丰收、赤霉素对切花洋桔梗生长发育及开花的影响。结果表明:易丰收使植株高度增加7.34~17.45cm,茎粗增加0.32~0.62mm,花径增大0.18~2.98cm,根量增加2.7~17.8条,花枝高度60cm以上的切花比例达到32.8%~91.9%,而且浓度越高花径越大,并且当易丰收浓度在0.050mL/L时现蕾期提前了8d;25~50mg/L赤霉素使植株高度增加8.1~11cm,茎粗增加0.2~0.4mm,花径增大2.2~2.7cm,花枝高度60cm以上的切花比例达到95.8%~98.0%,明显提高了洋桔梗切花质量。

摘  要:
The effect of EFS and Gibberellin with different concentrations on growth and blossoming of flower Eustoma was studied and analysed.The results showed that EFS increased the plant height 7.34~17.45 cm,stem diameter 0.32~0.62 mm,flower diameter 0.18~2.98 cm,the quantity of root 2.7~17.8 article,the ratio of cut flower height more than 60 cm reached 32.8%~91.9%,and the higher concentration of EFS,the larger of the flower diameter,and the squaring period ahead of 8 days with the EFS concentration at 0.05 mL/L;gibberellin of 25~50 mg/L increased the plant height 8.1~11 cm,stem diameter 0.2~0.4 mm,flower diameter 2.2~2.7 cm.The ratio of cut flower height more than 60 cm reached 95.8%~98.0%,obviously improves the quality of eustoma cut flowers.
