易丰收与赤霉素对切花洋桔梗生长发育的研究

EFS and Gibberellin on Growth and Development of Cut Flower Eustoma

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。

Abstract：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 than60 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/IAgibberellin 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.
