以香石竹（Ｄｉａｎｔｈｕｓ ｃａｒｙｏｐｙｌｌｕｓ Ｌ．）带病毒组培苗和扦插苗作为对照，研究香石竹脱病毒苗在苗期和花期的生长发育特性。实验结果表明，在苗期，香石竹脱病毒苗在株高、叶片数、分枝数、叶面积和根、茎、叶的干重等大多数营养生长发育指标明显优于对照。在花期，脱病毒苗在花苞和花朵直径，花枝高度和粗度等花质量指标明显优于对照，且脱掉病毒显著提高了花产量，缩短了生长发育期。
Tissue culture seedlings and cutting seedlings of Dianthus caryopyllus L. were used as a control to study the growth and development characteristics of the carnation virus-free seedlings at seedling and anthesis. The results showed that most of the indexes of growth, growth, development of carnation virus-free seedlings in plant height, number of leaves, number of branches, leaf area, dry weight of roots, stems and leaves were obviously better than those of the control. At florescence, the flower quality indicators such as flower bud and flower diameter, flower height and thickness of the virus-free seedling were obviously better than those of the control, and removal of the virus significantly increased the flower yield and shortened the growth and development period.
