Problems solved by technology

It can be seen that the storage temperature and humidity of various plant pollen and the method of thawing are not the same, but there is no way to maintain the vitality of water lily pollen within a month or so.

Embodiment Construction

[0017] Below in conjunction with the embodiment of the water lily kind called " luxury ", the present invention will be further described.

[0018] This embodiment includes the following steps:

[0019] 1) Collection and drying of water lily pollen

[0020] Collect dozens of mature water lily flowers, collect stamen pollen on sulfuric acid paper with tweezers, dry it naturally for 30 minutes, put it into an aluminum foil paper bag, and then pack the aluminum foil paper into a centrifuge tube to seal.

[0021] 2) Low temperature storage

[0022] Put the centrifuge tube containing the water lily pollen into the freezer of the refrigerator at -20°C for frozen storage;

[0023] 3) Relief transition before water lily pollen is thawed and used

[0024] Transfer the centrifuge tube containing water lily pollen from the refrigerator freezer at -20°C to the refrigerator freezer at 4°C for 4 hours;

[0025] 4) Water lily pollen restores vitality

[0026] Take out the centrif...

Abstract

The invention discloses a method for keeping water lily pollen viability, which comprises the following steps: 1) drying the water lily pollen naturally for 39 min and packaging and sealing thereafter; 2) storing in a refrigerator at a temperature of -20 DEG C; 3) transferring water lily pollen to a refrigerator refrigerating chamber at a temperature of 4 DEG C for 4 hours for transition; 4) taking out the water lily pollen and then putting it into a container with filter paper saturated with water for 30 min in order to have the water lily pollen reabsorb air moisture to resume viability. In this way, the viability of the water lily pollen can be maintained over a month, and water lily pollination isn't influenced, which solves the problems of blossoming of flowers at different times and pollination in different places in the process of water lily cross breeding.

Description

technical field [0001] The invention relates to a method for hybrid breeding of water lilies, in particular to a method for maintaining the vitality of water lily pollen within a not too long period of about one month, and belongs to the technical field of hybrid breeding of ornamental plants. Background technique [0002] Nymphaea is a genus of Nymphaeaceae ( Nymphaea ) A general term for plants, water lilies are deeply loved by people for their rich colors, holy implication, and strong adsorption capacity of stems and leaves to nutrient and harmful substances in water, and are widely used in garden waterscapes. May to October is the natural flowering period of various cold-resistant water lily varieties. In the process of cross-breeding, it often occurs that the flowering period cannot be reproduced, which further forms reproductive isolation. Preserving the collected water lily pollen for a period of time is one of the important ways to solve the problem of flowering. ...
