Bunch-flowered daffodil is elegant and generous, and relatively easy to feed, suitable for families to plant. Bunch-flowered daffodil has many propagation methods, and the common ones are side bulb propagation, side bud propagation, double scale propagation. The following is a detailed introduction to the Bunch-flowered daffodil propagation method.
Side bulb propagation is the first method of how to propagate bunch-flowered daffodils. It is also the most common method of propagation of Bunch-flowered daffodil. The ball is grown on both sides of the bulb, and only the base is connected to the cue ball, which is easy to detach from the mother. It should be separated from the cue ball in the autumn, and planted separately, so that new balls will be produced in the following year.
The side buds of the bunch-flowered daffodil are wrapped inside the bulb bulb. The Bunch-flowered daffodil can be used to propagate the bunch-flowered daffodil. It can be used to propagate the bunch-flowered daffodil. This method of propagation of Bunch-flowered Daffodil is performed only when the bulb is castrated, and the white buds are picked out along with the broken scales, and spread on the seedbed in the fall, so that new bulbs will be produced the following year.
Double scale propagation method of bunch-flowered daffodil uses a bulb disc with two scales as the propagation material. Specific operation method: first of all, the bulb is placed in a low temperature of 4-10℃ for 4-8 weeks. After removing, cut the bulbs into small discs at room temperature, so that each bulb disc has two scales, and the upper ends of the scales should be removed, leaving 2 cm for breeding material.
Then put the vermiculite with 50% water or sand with 6% water in a plastic bag. When it is ready, put the propagation material into a bag, close the mouth of the bag, and put it in a place of 20-28℃, and in a dark place. In this way, after 2-3 months, small bulbs can grow, and the pellet rate is 80-90%. Double scale propagation method of Bunch-flowered daffodil is new, but it can be done in all seasons, with April to September being the best time. The resulting bulbs have a high survival rate of 80-100% after transplanting.
The specific tissue culture propagation method of Bunch-flowered daffodil is: use MS medium, add 30 grams of sucrose and 5 grams of activated carbon per liter, use bud tip as explant, or use double scale stem plate 5×10 mm as explant can be, pH value is 5-7 is the best.
They were then placed in 20x100 mm glass tubes with 10 ml of medium per tube. After disinfection, one explant was implanted in each tube and cultured at a temperature of 25 ° C. After 10 days of inoculation, the explants produced small projections and formed into pellets after 20 days.
The survival rate of Tissue culture propagation method of Bunch-flowered daffodil is very high, after 6-8 weeks there will be leaves, roots, transplanting in the field, there is a 100% survival rate. And this use of stem tips as explants, and to the role of the virus, is a very good method of propagation.
