Problems solved by technology

The self-fertilization of Iris germanica is not fruitful. Therefore, most of the seeds of Iris germanica are hybrid seeds. The extremely low seed germination rate greatly limits the renewal speed of varieties and the construction of offspring hybrid populations, which in turn directly affects the inheritance of related traits. Analysis and Improvement
[0005] At present, there are no related reports on the germination of Iris germanica seeds, so a method that is relatively low in cost, simple to operate and can effectively improve the germination rate of Iris germanica seeds is provided. For improving the breeding efficiency of Iris germanica, related The genetic analysis and improvement of traits and large-scale production of seedlings are of great significance

Embodiment 1

[0028] (1) At the beginning of May, after the German iris fully bloomed, the hybridization work between different varieties was carried out. In late July, the fruits matured one after another, and the pods cracked. Dry in the shade for 20-30 days, then put it into a paper bag or plastic bag or bottle, and store it in a refrigerator at 4°C for later use.

[0029] (2) At the end of October, soak all the collected seeds. First, use gauze, suture three sides, and keep an opening, put the seeds of each hybrid combination into gauze bags of different specifications according to the quantity, seal them, and mark them; then put the seeds in the fresh-keeping box, pour distilled water, top Cover the bowl or other heavy objects to fix the seed bag and press it into the water. Change the water once a day for 10 days, and keep the temperature at 25°C±1°C.

[0030] (3) After soaking the seeds, pour out the water, pour in an aqueous solution of sodium hypochlorite with 3% available chlorin...

Embodiment 2

[0036] (1) At the beginning of May, after the German iris fully bloomed, the hybridization work between different varieties was carried out. In late July, the fruits matured one after another, and the pods cracked. Dry it in the shade for 20-30 days, then put it in an envelope, and store it in a refrigerator at 4°C for later use.

[0037] (2) At the end of October, soak all the collected seeds. First, use gauze, suture three sides, keep an opening, make gauze bags of different sizes according to needs, put the seeds of each hybrid combination into gauze bags of different specifications according to the quantity, seal them, and make a mark; then put the seeds Put it in a fresh-keeping box, pour it into the distilled aqueous solution containing 100ppm gibberellin and auxin (the mixing volume ratio of gibberellin and auxin is 1:1), cover the top with a bowl or other heavy objects to fix the seed bag and Press it below the liquid level, soak for 3 hours, and keep the temperature ...

Abstract

The invention discloses a method for promoting seed germination of iris germanica, and relates to the technical field of ornamental horticulture breeding. The method comprises the following steps: removing capsules from hybrid fruits, threshing, removing foreign matters, naturally drying in the shade, bagging and putting into a refrigerator of 4 DEG C for storing; and soaking into a soaking liquid for disinfecting, putting disinfected seeds into an environment at the temperature of 3-8 DEG for laminating for 42-63 days, performing sprouting culture and sowing. By adopting the method, the seed germination rate is increased to over 70 percent, the seedling quality is high, the cost is low, the treatment process and treated seeds are free from toxic and side effects, the risk to seed contact people is eliminated, and environmental pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of ornamental horticultural breeding, in particular to a technology for promoting germination of german iris seeds. Background technique [0002] German iris ( Iris germanica ) Department of Iridaceae, Iris genus, perennial herb. The leaves of Iris germanica are long and narrow, basal, arranged in 2 rows, the lower part of the leaves is often folded along the midrib, so that the bases of the alternate leaves overlap and clasp the stems, forming a folded sheath; 6 perianths, divided into two inner and outer rounds, outer perianth pieces, inner bases Beards of various colors are one of the signs of different varieties; the rhizome is thick and fat, which is an important nutrient storage organ and reproductive organ. German iris is a natural hybrid native to Europe, and it is also an important parent of modern bearded iris hybrid breeding. Nowadays, most of the bearded iris planted in courtyards and garde...
