Transplanting date and density are the important factors affecting the appearance quality of chrysanthemum. The study on the greenhouse single-flower cut chrysanthemum (Chrysanthemum morifolium cv. Shenma) showed that within the ranges of test transplanting date and density, the plant height and neck length increased, while the leaf number per plant, stem diameter, plant fresh mass and flower diameter decreased with the delay of transplanting date and the increase of transplanting density. No effect of transplanting density was observed on plant height. For the production of single-flower cut chrysanthemum in non-heated greenhouse in Shanghai, the optimal transplanting date and density to achieve the top rank of quality (rank A) were the middle ten days of August and 64 plants x m(-2), and those to achieve the second rank of quality (rank B) were from mid August to early September and 72-80 plants x m(-2), respectively. The results obtained in this study offered references in establishing the prediction model of greenhouse single-flower cut chrysanthemum appearance quality based on light, temperature, and transplanting date and density.

 

GC-MS analysis of essential oil from Xiaoboju processed by aeration-desiccation and sulfur-burnin fumigation.:Zhongguo Zhong Yao Za Zhi. 2007 May;32(9):808-13. Chinese.Wang YJ, Guo QS, Yang XW, Xu WB.Institute of Chinese Medicinal Materials, Nanjing Agricultural University, Nanjing 210095, China.

 

OBJECTIVE:

Analysis of the constituents of the essential oil extracted from the Xiaoboju, one of commercial breed came from the flowers of the Chrysanthemum morifolium, processed by the aeration-desiccation and desiccation after the sulfur-bumin fumigation, and to provide scientific basis for quality control.

 

METHOD:

The essential oil was extracted by water-steam distillation and separated by GC capillary column chromatography. The components were quantitatively determined with normalization method, and identified by GC-MS.

 

RESULT:

From the aeration dried sample and the dried sample after sulfur-burnin fumigation, 216 and 211 components were detected, among them fifty and six-five components were identified, which were composed of 73.21% and 82.32% of the total essential oil, respectively.

 

CONCLUSION:

The yield of the essential oil extracted from the aeration dried sample was 3.50%, and that from the dried sample after sulfur-bumin fumigation was 4.22%. The latter is 1.2 times higher than the former. The components of the essential oil of both samples are mostly monoterpenoids and secondly sesquiterpenoids compounds, but there are marked differences between the compounds contained in the two samples. Therefore, the processing of flowers of the C. morifolium should be strictly controlled and standardized.
