The invention provides a method for high-pressure propagation and rapid seedling culture of acanthopanax giraldii harms, and belongs to the technical field of rapid propagation of acanthopanax giraldii harms. The method comprises the following steps: 1-3 days before high-pressure propagation in April to August, shading seed trees of acanthopanax giraldii harms; the method comprises the following steps: selecting branches which grow for more than or equal to 1 year on an acanthopanax giraldii harms seed tree, girdling, and scraping away phloem of the girdled part; carbendazim, a rooting solution 1 and a rooting substrate are mixed and filled into a breeding box, the breeding box is pressed at the branch girdling position, a girdling notch is kept in the dead center of the breeding box, and the breeding box is fixed; the relative humidity of the rooting substrate in the breeding box is kept to be 70%-80%, and a rooting promoting nutrient solution is supplemented regularly. According to the method, the problems of microbial contamination and browning in traditional tissue culture are solved, only 4-6 months are needed, the seedling culture time of the acanthopanax giraldii harms is greatly shortened, and the reproduction rate and the branch utilization rate are remarkably increased; the rooting rate and the survival rate both reach 90% or above, and the material cost and the time cost are saved.

The utility model belongs to the technical field of forestry, and particularly relates to an endangered plant seed ground touching natural germination auxiliary device which comprises a box body with two open ends, a box cover is installed on the box body, a plurality of through holes are formed in the box cover, fruit receiving devices are installed in the through holes, an inserting groove is formed in one end of the box body, the box body is provided with a protruding strip, and the protruding strip is connected with the inserting groove. The space between the box cover and the net plate is used for being filled with matrix soil, the fruit receiving device comprises a hopper and an insertion pipe, the insertion pipe is arranged in the through hole in a penetrating mode, a filter hole is formed in the hopper, a cross rod is arranged on the hopper in a penetrating mode, a suspended conical cover is installed on the cross rod, the outer diameter of the conical cover is larger than that of the insertion pipe, and the outer diameter of the conical cover is larger than that of the insertion pipe. The method is used for solving the problems of low seed germination rate and inconvenience in protection of endangered plants due to difficulty in ground germination of seed tree species and easiness in ingestion of the seeds by animals after the seeds fall to the ground at present.

The invention relates to the technical field of plant tissue culture and endangered tree seed breeding, in particular to an efficient embryo germination culture method for breaking through the deep dormancy characteristic of tilia amurensis, and aims at solving the problems that existing tilia amurensis seed breeding is low in germination rate, long in period, high in pollution rate and poor in embryo seedling quality. The method comprises the following steps: selecting robust tilia amurensis seed trees in specific areas such as 129 degrees, 19 '+ / -0.5 degrees and the like of the east longitude, and harvesting seeds with the water content of 45.25%-59.06% from August 29 to September 20; stratification is conducted at the low temperature of 4 DEG C for 20 days, 50 mg / L GA3 is added, soaking is conducted for 12 h, and pretreatment Precisely disinfecting with 75% alcohol and 2% sodium hypochlorite; cutting a 1-2mm notch on the seed coat, and then carrying out antioxidant treatment by using a vitamin C-humic acid solution; inoculating to an optimized MS culture medium containing hormones such as 0.1 mg / L 6-BA, carrying out dark culture at 22 DEG C for 5 days, and then carrying out 2000lx illumination culture at 24 DEG C; according to the method, deep dormancy is efficiently broken, the pollution rate is low, embryo seedlings are robust, and large-scale breeding and population recovery of tilia amurensis can be supported.

A new and distinct cultivar of orange plant named ‘Orange 14’, an allotetraploid rootstock with improved disease resistance for use in HLB-endemic areas. This cultivar produces adequate nucellar seed making it amenable to standard nursery propagation practices for uniform liner production. Ungrafted seed trees are especially tolerant of HLB.
