Embodiment Construction

[0030] The key factor for interspecific hybridization to obtain hybrids is not only the degree of compatibility between species, but also the vitality of male and female gametophytes. In the process of hybrid seed production of Magnolia magnolia × Purple Magnolia, maintaining pollen viability and capturing the best fertilization period are the main implementation measures in the seed production process.

[0031] (1) Optimization of the best storage conditions for magnolia pollen

[0032]1. Changes in the relative water content of magnolia pollen at different drying times

[0033] Taking non-dried fresh pollen as a control, the changes of relative water content of pollen under different drying time treatments are shown in Table 1. With the extension of drying time, the relative water content of pollen decreased gradually. The water loss rate of pollen dried for 2 hours was the fastest, and the relative water content decreased by 8.50%. Compared with 2h, the relative water co...

Abstract

The invention discloses a method for breeding a Magnolia grandiflora-magnolia liliiflora hybrid. According to the method, at first, magnolia liliiflora pollen as a male parent obtained in the magnolia liliiflora flowering phase earlier two months than the Magnolia grandiflora flowering phase is preserved and maintains pollen activity by collecting initially open magnolia liliiflora flowers, taking out stamens, uniformly spreading the stamens on a vegetable parchment, naturally drying at a room temperature, after anthers of the stamens crack and pollen is spilled out, collecting the pollen by an iron screen of 80 meshes, drying it in a dry silicon dish by a filter paper bag, closely wrapping the dried pollen by a silver paper, preserving the wrapped pollen under the freezer condition of a temperature of -70 DEG C, and before use, taking out the pollen and carrying out stepwise heating thawing. The method also comprises determination of the best pollination period of Magnolia grandiflora as a female parent, cross pollination reproductive biology basic research, hybrid fruit and hybrid development situation observation and breeding and preservation methods. The method for hybridization can be operated easily and can effectively produce Magnolia grandiflora-magnolia liliiflora hybrid seeds.

Description

1. Technical field [0001] The invention relates to the field of hybrid advantage utilization in forestry, in particular to a method for hybrid seed production of American magnolia (female parent) and purple magnolia (male parent). 2. Background technology [0002] With the rapid development of my country's economy and the continuous improvement of people's lives, people's demand for the types and quality of environmental greening plants is getting higher and higher. Therefore, the breeding of garden plants has become one of the preferred industries for agricultural and forestry economic development. However, compared with developed countries, there are very few types of garden plant resources in my country, and the number of fine ornamental varieties of garden plants can no longer meet the needs of my country's rapid economic development. Therefore, it is necessary to vigorously strengthen the cultivation of new strains of garden plants, which can not only efficiently, high-...
