Water lilies are important flowers that are widely cultivated in gardens for both ornaments and water purification ( Huang et al., 2009 ). The genus Nymphaea could be classified into six subgenera, i.e., Anecphya , Brachyceras , Confluentes

A synthetic F1 water-lily hybrid has been obtained for the first time using parental species originating from different subgenera of Nymphaea. The cross was accomplished using Nymphaea gigantea Hook. `Andre Leu' (subgenus Anecphya Casp.) as the maternal parent and a white-flowered variant of Nymphaea colorata Peter (subgenus Brachyceras Casp.) as the paternal parent. Morphologically, the hybrid possesses some characteristics of both parents, some intermediate features, and some unique traits. The cross was confirmed using DNA sequencing and molecular cloning techniques to compare biparentally inherited nuclear genetic markers in the parents and hybrid plant. Each parent possessed distinct alleles that were found to combine in the hybrid. Maternally inherited chloroplast DNA sequences confirmed N. gigantea as the maternal parent of the cross.

Effects of two pretreatments, i.e., ultrasonic wave (UW) and ultrasonic wave plus preservative solution (UW+PS), on water conditions of flower stem and membrane stability of petals in Nymphaea tetragona during 6-d cold wet storage. Compared with no pretreatment control, the two pretreatments prolonged the vase life and improved water conditions of the cut flower during cold storage to different degrees. Fresh weight of flower stems and relative water content of petals increased during cold storage. The water utilization efficiency of flower stem and water potential in different parts of flower stem were improved significantly as a result of the pretreatments. Although both pretreatments helped the cut flowers maintain favorable water relations, the effects of UW + PS combined pretreatment were better than UW pretreatment alone. In addition, UW and UW+PS inhibited the increase in the contents of lipid peroxidation product malondialdehyde (MDA) and superoxide anion in petals. UW + PS promoted superoxide dismutase (SOD) and catalase (CAT) activities in petals during cold storage to a greater degree than did UW.
