摘要
参照其它花卉分级评定标准,并结合与同行探讨,通过对睡莲品种10个主要观赏性状的观察记录,制定了一套睡莲观赏性状评比标准,进而对31个新引种耐寒睡莲新品种打分、分级,作定量评定。运用统计分析的方法,规定>84.6分为甲级（有6个品种）;70.2～84.6分为乙级（有21个品种）;<70.2分为丙级（有4个品种）。评比结果可为睡莲的引种栽培、杂交育种等提供一定的参考依据。
On the basis of evaluation graded evaluation criterion of other flowers and viewpoints of the same trade experts, an evaluation criterion for hardy water lilies (Nymphaea spp.) was made according to the observational records of ten main ornamental characteristics. Thirty-one varieties were then evaluated by this criterion and classified into 3 grades. Those having a score more than 84.6 were defined as the first grade, between 70.2 and 84.6 the second grade, and less than 70.2 the third grade. So there were 6,21 and 4 varieties in the three grades respectively. The results could provide reference basis for the introduction, cultivation and cross breeding of water lilies.
