Embodiment 1
[0027] This embodiment provides a method for overwintering storage of subgenus Nymphaea, realizes the overwintering storage of dormant stems of subgenus Nymphaea, and the obtained dormant stems have strong vitality, providing ideal propagation materials for the propagation of subgenus Nymphaea . The method includes the following steps:
[0028] Step 1. Harvesting and processing of dormant stems
[0029] One week after the first frost, excavate the Nymphaea plants growing in the open air, remove the leaves and roots on the plants, obtain the dormant stems that have formed, and wash the soil and debris on the dormant stems with clean water.
[0030] The wide tropical subgenus of water lilies planted in Xi'an Botanical Garden in Shaanxi Province, including blue crab claw ( N. ‘NangkwaugDeng’ (Blue)), Red Lilac ( N. ‘Red Persian Lilac’), Ruby ( N. 'Ruby'), Blue Star ( N. colorata ), Islamada ( N. ‘Islamorada’), red crab claws ( N. 'Nangkwaug Deng' (Red)) and other 6 ...
Embodiment 2
[0037] The present embodiment provides a method for overwintering Nymphaea subgenus Nymphaea subgenus, that is, using the dormant stems obtained by the method described in Example 1 as propagation materials to form Nymphaea seedlings of Nymphaea subgenus Nymphaea. On March 15, 2016, the stored dormant stems were soaked in water to accelerate germination. The soaking time was 2 months. The germination of the dormant stems was observed, and the survival rate was counted.
[0038] The germination experiment found that most of the dormant stems had germinated, and the underground stems that had not germinated but remained hard were also considered to be alive.
[0039] Table 1 Statistical results of survival rate of different varieties of dormant stems after storage
[0040] water lily species
[0041]From the results in Table 1, it can be seen that the dormant stems of blue crab claw, red clove, Ruby, blue star, Islama, red crab claw and other varieties have a high surv...
