Problems solved by technology

The development and utilization of the semi-mangrove plant P. japonicus is an urgent need in production. Due to production needs and the limitations of existing seedling raising techniques, the current P. japonicus seedlings have a low germination rate and long germination time, and the existing P. japonicus uses The method of seedling breeding has high cost and low reproduction efficiency, so there is an urgent need for an efficient and large-scale breeding method for P.

Embodiment 1

[0023] Such as figure 1 Shown, a kind of water yellow skin seedling rapid and high-efficiency breeding method comprises the following concrete steps:

[0024] S1 collects ripe Pumgia fruit.

[0025] Specifically, by collecting the ripe fruit of Phonggum chinensis, and then putting it in the laboratory for future use.

[0026] S2. Put the fruit of P. chinensis in the room to air-dry naturally, and then remove the exocarp of the fruit of P. chinensis to obtain seeds of P. chinensis.

[0027] Specifically, put the Pumgia fruit that was put in the laboratory for natural air-drying, and then randomly and evenly divide the Pumgia fruit into test group 1, test group 2, test group 3, test group 4, test group 5, and test group 6 and test group 7, 60 capsules per serving. Described test group 1 is the intact fruit that does not remove exocarp, and test group 2, test group 3, test group 4, test group 5, test group 6 and test group 7 are all the Pseudomonas seeds with exocarp removed. ...

Embodiment 2

[0041] It is used to determine the effect of different concentrations of gibberellin aqueous solution soaking treatment on seed germination.

[0042] A kind of quick and high-efficiency propagation method of Pseudomonas seedlings comprises the following specific steps:

[0043] S1 collects ripe Pumgia fruit.

[0044] Specifically, by collecting the ripe fruit of Phonggum chinensis, and then putting it in the laboratory for future use.

[0045] S2. Put the fruit of P. chinensis in the room to air-dry naturally, and then remove the exocarp of the fruit of P. chinensis to obtain seeds of P. chinensis.

[0046] Specifically, the exocarp was removed from the fruits of P. japonica, and they were randomly divided into 4 equal parts, each with 60 grains, which were respectively marked as test groups 8-11.

[0047] S3 selects an aqueous solution of gibberellin, and then soaks the seeds of Pseudomonas in the aqueous solution of gibberellin.

[0048] Specifically, it can be seen from ...

Abstract

The invention provides a rapid and efficient breeding method for a pongamia pinnata seedling, comprising the following specific steps of collecting a mature pongamia pinnata fruit, placing the pongamia pinnata fruit in the room, naturally air-drying, and then removing the peel of the pongamia pinnata fruit to obtain a pongamia pinnata seed; selecting an gibberellin aqueous solution, then immersingthe pongamia pinnata seed in the gibberellin aqueous solution, preparing a sand bed, sowing the pongamia pinnata seed after soaking in the sand bed, and finally enabling the pongamia pinnata seed togerminate, and then grow into a pongamia pinnata seedling; by using the pongamia pinnata seed as a material for rapid and efficient seedling raising, the germination time of the pongamia pinnata seedis advanced by 20 days or more, the seed germination rate is 95% or above, the seedling transplanting survival rate reaches 90%, and uniform high-quality pongamia pinnata seedlings are produced; a rapid and efficient breeding system of pongamia pinnata seedlings is established, and an effective solution is provided for meeting the urgent needs of the pongamia pinnata seedlings and recovery protection and resource development and utilization.

Description

technical field [0001] The invention relates to the field of plant planting methods, in particular to a method for rapid and efficient breeding of japonica seedlings. Background technique [0002] Pongamia pinnata belongs to the genus Pongamia of the family Leguminosae. Trees, 8-15m tall. Young branches are usually glabrous, sometimes slightly puberulent, and old branches are densely gray-white with small lenticels. The pods are 4-5 cm long and 1.5-2.5 cm wide, with inconspicuous small warts on the surface, a slightly curved short beak at the top, no cracks, no raised edges or wings along the suture, and 1 seed; Seeds reniform. The flowering period is from May to June, and the fruiting period is from August to October. Produced in Fujian, Guangdong (southeast coastal areas), Hainan. Born in places where streams, ponds and seaside tides can reach. It is also distributed in India, Sri Lanka, Malaysia, Australia, and Polynesia. The wood texture of pongamia is dense and b...
