Sucrose (30,40, 50 g· L-1) , 8-hydroxyquinoline (100, 200, 300 mg·L-1), salicylic acid (75, 100, 150 mg · L-1), and CaCl2( 150, 200, 250 mg · L-1) were used as the four factors of blooming promoters. An orthogonal experimental design for four control factors, each at three levels were made to screen the optimal blooming promoter combinations and the main influence factor for ' Shenma' cut chrysanthemum through test about forcing with bottle inserts. The optimal blooming promoters were obtained by the further verification test. The optimal blooming promoters were obtained as sucrose 50 g · L-1, 8-hydroxyquinoline 300 mg · L-1, salicylic acid 75 mg · L-1, and CaCl2 150 mg · L-1. Sucrose is the main influence factor. A highly significant difference was found between the optimal blooming promoters and the control. The optimal blooming promoters could speed up budding in 3 days, which made the cut flowers blossom half a month earlier than those cultured in the open, and made the whole cut chrysanthemum come up to the standard during the process of flower forcing. Moreover, the optimal blooming promoters could promote the water absorption ability of the cut flowers, and obviously improve the contents of soluble protein and soluble sugar in petals. The maximum contents of soluble protein and sugar were 7.125 and 0.042 6 mg · g-1, respectively, which were both higher than the maximum value of other treatments. The activity of POD in petals preferably enhanced and the SOD activity maintained stable.%以蔗糖(质量浓度分别为30、40、50 g·L-1)、8-羟基喹啉(质量浓度分别为100、200、300 mg·L-1)、水扬酸(质量浓度分别为75、100、150 mg·L-1)、氯化钙(质量浓度分别为150、200、250 mg·L-1)为催花液4因素,采用4因素3水平正交试验设计,通过瓶插催花试验筛选出‘神马’切花菊蕾期采后最佳催花液组合及主效因素.通过进一步验证试验,验证最佳催花液.结果表明:正交试验得到‘神马’切花菊蕾期采后最佳催花液为50 g·L-1蔗糖+300 mg·L-18-羟基喹啉+75 mg·L-1水杨酸+150 mg·L-1氯化钙,主效因素为蔗糖.在验证试验中,最佳催花液处理与对照相比差异极显著,能够在3d内催开花蕾,使切花比露地早半个月开花,并使其整体达到催开标准；提高花枝的水分吸收能力及花瓣中可溶性蛋白和可溶性糖的质量分数,其中蛋白质质量分数最高可达到7.125 mg·g-1,可溶性糖质量分数最高可达到0.0426 mg·g-1,均高于对照及其他处理的最高值；花辨中POD酶活性增强,SOD酶活性相对平稳.
