Narcissus breeding method

[ Agricultural Products Network] Narcissus, also known as Chinese Narcissus , is a variant of the multi-flowered daffodil. Narcissus is warm, moist and well drained. It has a history of more than a thousand years of cultivation in China. It is a traditional ornamental flower and is one of the top ten famous flowers in China. Let's look at how the narcissus is reproduced:

Lateral ball breeding

This is a common breeding method commonly used by ZUI. The storage ball is placed on both sides of the bulb ball. Only the base is connected to the cue ball. It is easy to separate from the mother body. In the autumn, it is separated from the cue ball and planted separately. The new ball is produced the following year.

Lateral bud reproduction

Lateral buds are buds that are enclosed inside the bulbous ball. Only when the bulbectomy is carried out, the broken scales are separated from the mother body, the white buds are picked out, and the autumn is spread on the seedbed, and a new ball is produced in the following year.

Double scale reproduction

A bulbous bulb contains many lateral buds that are clearly visible and hidden. But the basic rule is to have two buds and one bud. The use of a bulb with two scales as a propagation material is called double scale propagation. The method is to place the bulbs at a low temperature of 4-10 ° C for 4-8 weeks, then cut the bulbs at room temperature, so that each piece has two scales, and the upper end of the scales is cut to leave 2 cm as a propagation material. Then, use a plastic bag to hold 50% water containing vermiculite or 6% water containing sand, put the propagation material into the bag, close the bag mouth, and place the dark place at a temperature of 20-28 °C. Small bulbs can be grown in 2-3 months, and the ball formation rate is 80-90%. This is a new method that has been developed in recent years. It can be carried out in all seasons, but it is better from April to September. The survival rate of the generated small bulbs after transplanting is high, up to 80-100%.

Tissue culture

The MS media, 30 g per liter of sucrose and an additional 5 g activated carbon, with the shoot tips explants, or a disc having a double stem scales 5 × 10 mm explants, PH value 5-7; means Into a 20x100 mm glass tube, 10 ml of medium per tube, after disinfection, implant one explant per tube, then culture at 25 ° C, produce small protrusions after 10 days of inoculation, and become small balls after 20 days, January After transfer to a medium containing NAA0.1/mg 1/2 MS, leaves and roots after 6-8 weeks, transplanted in the field, can survive 100%. The use of shoot tips for explants also has the effect of removing viruses.
