A brief introduction to the breeding methods of New Guinea Impatiens

New Guinea Impatiens belongs to the family Impatiens, which is native to the tropical mountains of Africa, but has recently been developed into a dwarf variety in Japan and has become more popular. The editor will give you a brief introduction to the main breeding methods of New Guinea impatiens.

New Guinea Impatiens

Sowing, tissue culture and cutting are the main propagation methods of New Guinea impatiens. The time of sowing and propagation is generally from March to April, which is harvested in time and sowed with picking. The optimum temperature for germination is 22 degrees. The method of tissue culture propagation has been successful and large-scale production has been started. Because the self-pollination ability of New Guinea impatiens is poor and the cost of tissue culture is high, cutting method is often used to propagate. The cutting season is suitable for spring, summer and early autumn, and can be propagated year-round in the greenhouse. The cuttings can be collected directly from the buds in the axils of the leaves for microcutting, and the propagation speed is quite fast; the branches of the current year can also be cut into several segments, each with 2-3 nodes. The cutting substrate can be made of plain sand or vermiculite. In order to improve the rooting rate of cuttings, the cuttings were quickly dipped with ABT rooting powder, and the new roots were produced in 5-6 days. After 2 weeks, when the roots were 2~3cm, they could be put on the pot.

New Guinea Impatiens is another name for the Impatiens family, and the four Seasons Impatiens is a perennial herbaceous ornamental flower of the genus Impatiens. Next, we will share with you the breeding methods and breeding methods of New Guinea Impatiens.

Culture methods of New Guinea Impatiens

Soil: new Guinea Impatiens has strong adaptability to soil, and the pH value should be controlled between 5.5 and 6.5. Rotten leaf soil, vegetable garden soil and sand should be mixed with 5 ∶ 3 ∶ 2 to form loose, fertile and breathable sandy soil.

Temperature: new Guinea impatiens prefer a warm environment, the suitable temperature for growth is 20-25 ℃, the flowers will become smaller if the temperature is more than 25 ℃, and the relative humidity must be increased if the temperature is over 30 ℃ to keep the plant growing. When the temperature is relatively low, the growth of New Guinea impatiens stops, and when the temperature drops below 7 ℃, it will suffer frost damage.

Illumination: new Guinea impatiens like plenty of sunshine, avoid scorching sun exposure, and should be properly shaded in summer. In winter, New Guinea Impatiens will be placed in an indoor light place to fully receive light.

Humidity: new Guinea impatiens like to be wet and afraid of drought, avoid waterlogging, and it is easy to cause fallen flowers and leaves when the moisture is insufficient. The basin soil should be dry and wet, and it should be watered until the bottom of the basin comes out of the water. waterlogging will rot the roots and branches and leaves will wither if it is too dry. The most important part of family maintenance is to maintain a certain air humidity, it is appropriate to often spray water to the plant.

Fertilization: new Guinea impatiens has a long flowering period and usually needs a lot of nutrients, so you can apply some nitrogen fertilizer appropriately at the seedling stage. During the growing period and flowering period, nitrogen, phosphorus and potassium compound fertilizer should be applied once from 10 to 15 days. Avoid single application of nitrogen fertilizer, otherwise there will be more leaves and less flowers. If you accidentally stick the fertilizer on the leaves during fertilization, you should spray water and wash it off in time.

Breeding methods of New Guinea Impatiens

The common propagation methods of New Guinea impatiens are sowing, tissue culture and cutting. The best time for sowing and reproduction is from March to April of each year. Because of the high cost of tissue culture propagation, cutting method is often used for propagation.

The cuttings of New Guinea impatiens can be carried out in spring, summer and autumn, and can be propagated throughout the year in the greenhouse. The cuttings can be directly collected from the buds in the axils of leaves for microcutting, and the propagation speed is quite fast.

New Guinea Impatiens can also cut the branches of the year into several segments, each with 2-3 nodes. The cutting substrate can be made of plain sand or vermiculite. In order to improve the rooting rate of cuttings, the cuttings were quickly dipped with ABT rooting powder, and the new roots were produced in 5-6 days. After 2 weeks, when the root length was 2-3cm, the cuttings could be put on the pot.

New Guinea Impatiens is rich and delicate in color and is often used to decorate desks, windowsills and other places. Friends who like New Guinea impatiens all want to breed in large numbers, so how do New Guinea impatiens breed? What kind of fancy words do you have? Let's learn about it next.

I. breeding methods of New Guinea Impatiens

The propagation of New Guinea impatiens can be divided into three methods: sowing, cutting and tissue culture, which are rarely used because of the high cost of tissue culture.

1. Sowing and propagation: the sowing time is generally from March to April, timely harvesting and sowing with picking. The optimum temperature for germination is 22 degrees. The method of tissue culture propagation has been successful and large-scale production has been started. Because the self-pollination ability of New Guinea impatiens is poor and the cost of tissue culture is high, cutting method is often used to propagate.

2. Cutting propagation: spring, summer and early autumn are suitable for cutting season, and annual propagation can be carried out in greenhouse. The cuttings can be collected directly from the buds in the axils of the leaves for micro-cutting, and the propagation speed is quite fast; the current year's branches can also be cut into several segments, each with 2-3 nodes. The cutting substrate can be made of plain sand or vermiculite. In order to improve the rooting rate of cuttings, the cuttings were quickly dipped with ABT rooting powder, and the new roots were produced in 5-6 days. After 2 weeks, when the root length was 2-3cm, the cuttings could be put on the pot.
