Abstract

The invention relates to a tissue culture method for German iris tectorum. The method comprises the following steps: (1) preparation of culture media: including the following ingredients and contents in each tissue culture stage: 1) bud inducing culture media: MS, and 1.0-5.0 mg / L of 6-BA and 0.1-0.5 mg / L of NAA; 2) adventitious bud proliferation culture media: MS, and 1.0-3.0 mg / L of 6-BA and 0.1-0.3 mg / L of NAA; 3) strong seedling culture media: MS, and 0.5-2.0 mg / L of 6-BA and 0.1-0.2 mg / L of NAA; 4), rooting culture media: MS and 0.05-0.2 mg / L of NAA; controlling the ph of the culture media under each condition to 5.8, adding 30 g / L of glucose and 6g / L of agar, and culturing at a temperature of 26 DEG C or 24 DEG C under the solar irradiation of about 80 micromol / ms. Compared with the prior art, the tissue culture method has the advantages that the reproduction speed and the tidiness of seedlings are greatly improved, and original female parent properties are better kept.

Description

technical field [0001] The invention relates to plant cultivation, in particular to a tissue culture method of German iris. Background technique [0002] German iris is a perennial herb of the family Iridaceae, native to central and southern Europe. It is now widely planted all over the world. Plant height 50CM. It has thick and fat rhizomes, clusters of sword-shaped leaves, slightly grayish green, purple and white flowers, and the flowering period is May-June. German irises have large, elegantly colored flowers. Hi warm, slightly humid and sunny environment. Cold-resistant, dry and semi-shady, afraid of stagnant water. It should be loose, fertile and well-drained calcareous soil. Iris plants have strong cold resistance, strong growth, beautiful leaves, large and colorful flowers, and are excellent flower viewing ground covers. This variety is widely used in gardens, suitable for potted plants, flower beds, and flower borders. It is also an important cut flower Materi...
