Embodiment Construction

[0010] The embodiments of the present invention will be further described in detail below.

[0011] Cattleya pollen storage method of the present invention, its preferred embodiment is:

[0012] Store Cattleya pollen dry at or below 4°C, or store Cattleya pollen wet at -20°C.

[0013] Cattleya pollen can be stored dry at 4°C to -20°C.

[0014] Cattleya pollen is preferably stored dry at -20°C.

[0015] The pollen block preservation method of this patent can preserve the pollen vigor for more than 2 years without affecting the pollination effect, which provides technical support for effective research on Cattleya hybrid breeding.

[0016] Specific experimental example:

[0017] Two methods of wet storage and dry storage were used, refrigerated at 4°C and frozen at -20°C, respectively. A total of 4 methods were used to store Cattleya pollen cubes. The experimental results are shown in Table 1.

[0018] The results showed that the germination rate of pollen decreased rapidly ...

Abstract

The invention discloses a Cattleya pollen storage method, which includes dry storage of Cattleya pollen at 4 DEG C and below or humid storage at -20 DEG C, preferably, dry storage at -20 DEG C. By the method, vitality of the Cattleya pollen can be maintained for more than 2 years, pollination effect is unaffected, and breeding is available all year round.

Description

technical field [0001] The invention relates to a pollen storage method, in particular to a cattleya pollen storage method. Background technique [0002] Cattleya belongs to family Orchideceae, subfamily Epidendroideae, tribe Epidendreae, subtribe Laeliinae, also known as Cattleya orchid, epiphytic compound stem orchid kind. It has colorful flowers, large and colorful flowers, fragrant and pleasant smell, and rich and colorful colors. It has the reputation of "king of foreign orchids" in the world. It is native to tropical and subtropical America, among which Colombia and Brazil are the most wild, and countries such as Colombia, Brazil, and Costa Rica even use Cattleya as their national flower. Cattelan is produced on a large scale in Thailand, Singapore, Indonesia, Malaysia, the Philippines and Taiwan, and these areas have become the main producing areas of Cattelan in the world. [0003] At present, there are about 110 native species of Cattleya (http: / / apps.kew.org / wcs...
