Embodiment 1

[0018] The method for promoting the germination of the very small population species Fumin trifoliate trifoliate seed in this embodiment comprises the following steps:

[0019] Step 1: Picking mature Fumin trifoliate fruit: On October 25, I went to Longma Village, Fumin County, Yunnan Province, the original place of Fumin trifoliate fruit, and harvested three Fumin trifoliate fruits that were planted relocated. On October 27, I went to Kunming World Expo Park to pick Harvest the 4 introduced and planted Fumin trifoliate fruits, and bring the harvested fruits back to the laboratory;

[0020] Step 2: Pre-treatment of seeds: Peel the fruit picked in step 1 indoors, take out the seeds, wash them in clean water, soak them for 12 hours, remove the unfulfilled seeds floating on the water surface, and spread the full seeds on the ventilated indoor ground Dry in the shade for 7 days;

[0021] Step 3: Accelerating germination: soak and disinfect the seeds after drying in the shade with...

Abstract

The invention discloses a method for promoting the seed germination of the extremely-small-population species Poncirus polyandra. The method for promoting seed germination of Poncirus polyandra comprises the following steps: stripping off ripe Poncirus polyandra fruits to obtain Poncirus polyandra seeds, drying the Poncirus polyandra seeds in a room in the shade for 7 d, soaking dried Poncirus polyandra seeds in a potassium permanganate solution with a concentration of 1% for disinfection for 15 minutes, then soaking disinfected Poncirus polyandra seeds with a rooting powder ABT No. 1 solutionwith a concentration of 2 kg / L for 24 h, and sowing treated Poncirus polyandra seeds onto a seedbed in a greenhouse, wherein seed germination and seedling emergence are realized in 25 to 30 d after completion of sowing. The method provided by the invention solves the problems of long germination time, low germination rate and untidy seedling emergence of the Poncirus polyandra seeds. The method provided by the invention enables the germination rate of the Poncirus polyandra seeds to reach 85% or above, shortens the time of germination, has the advantages of rapid propagation speed, short propagation period, high seedling emergence rate and tidy seedling emergence, and is of important significance to rescuing conservation, population genetic diversity increase and wild population reconstruction of the extremely-small-population species Poncirus polyandra.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a method for promoting the germination of the seeds of Fumin trifoliate trifoliate fruit in very small populations. Background technique [0002] Poncirus polyandra, also known as Poncirus polyandra, belongs to the Rutaceae Hovenia genus. It is a new species of Poncirus trifoliate discovered by Ding Suqin et al. in Donggualing, east of Laoqing Mountain, Fumin County, Yunnan Province. It has the characteristics of evergreen, strong cold resistance, and excellent dwarfing citrus rootstock species. Due to the narrowness of the original distribution area, and the serious disturbance and destruction of the original habitat, the wild resources of Fumin Trifoliate Fructus have been extremely reduced in the past 20 years, and its wild resources are on the verge of extinction. The "Emergency Action Plan for the Rescue and Protection of Extremely Small Population Spe...
