Abstract: This paper dealed with the growth and development properties of the de-virus carnation seedlings The tissue culture seedlings and xuttaging seedlings that infected by carnation mottle virus were used as control. The results indicated that the de-virus seedlings were obviously better than those of the control on most of leaf, and the dry matter weight of root, stem and leaf during the seedling period. The quality indexes such as the diameter of bud and flower, the height and width of stem during flowering period were also much better than those of the control. Furthermore, the yield of the virus-free seedlings can be improved and the period of growth and developmert can be shortened greatly.

摘要： 以香石竹(DianthuscaryophyllusL.)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.
