Five common propagation methods of Phalaenopsis

Phalaenopsis is an epiphytic orchid. When Phalaenopsis blossoms, it looks like a butterfly. It is very beautiful, so it has the reputation of "Queen of Phalaenopsis". However, Phalaenopsis planting requirements are relatively strict, so artificial cultivation of Phalaenopsis need to pay attention to cultivation methods, if you are interested in breeding Phalaenopsis yourself, you can refer to the five common breeding methods of Phalaenopsis arranged for you.

Phalaenopsis

I. method of sowing and breeding

There is a natural sowing method, which is to sow the seeds from the cracked capsule in the flowerpot of the parent plant. This method is simple and easy, does not need complicated aseptic procedures and operating tools, and is suitable for ordinary family Phalaenopsis growers. However, the chance of success of this method is slim, and it is rarely used. Another method is aseptic sowing, in which the uncracked mature capsule is washed, then soaked in 75% 90% ethanol or chloroform for 2 seconds, and then soaked in 5% 10% bleach solution or 3% hydrogen peroxide for 5 minutes for 20 minutes. Take out the seeds and soak them in the same disinfectant for 5 minutes, then remove the solution by filtration, take out the seeds, and spread the seeds evenly on the surface of the culture medium in the prepared bottle with fine needles. The culture conditions were as follows: light intensity 2000-3000 lux, 10-18 hours a day, and the temperature was kept at 20-26 ℃. After 9-10 months, the seedlings can grow 2-3 leaves and then be planted in pots.

2. Pedicel budding and reproduction

The method is to first cut off the flowering part of the pedicel, and then carefully remove the bracts of the first to third internodes in the upper part of the pedicel with a blade or sharp blade to expose the bud points in the internodes; apply hormones such as budding agents or indolebutyric acid evenly on the exposed Internode nodes with cotton swabs After treatment, the orchid plant was placed in a semi-shade place, and the temperature was kept at 25: 28 ℃. After 2 weeks, the buds grew into leaves, and after 3 months, they grew into Phalaenopsis seedlings with 3 leaves and aerial roots. cut off the seedlings and put them on the pot, they can become a new orchid plant.

Third, the method of broken heart and accelerating germination and reproduction.

After the growth point of the orchid plant is destroyed due to some factors, 1 or 2 new buds will grow from the stem node near the base of the orchid plant after a period of time. This feature can be used to breed Phalaenopsis.

IV. Stem cutting and breeding

The principle of stem cutting and reproduction is to destroy the growth point of stem tip to induce latent bud growth. Although there are 1-3 latent buds in the axils of Phalaenopsis plants, most of them can not sprout into plants. After the plant continues to grow upward and the stem node is longer, the upper part of the plant with roots is cut off with sterilized knives or scissors, implanted into a new basin to make it continue to grow, the lower part of the rhizome is given proper water management, and new buds can sprout soon.

5. Tissue culture method

The excellent genetic characteristics of Phalaenopsis can be obtained by using tissue culture to propagate Phalaenopsis. The butterfly orchid seedlings produced by this method are called meristem or tissue seedlings. The plant tissues (explants) used for meristematic culture can be terminal buds (stem tips), stem segments (dormant buds), young leaves or root tips, but at present the most common is the pedicel of Phalaenopsis.

Detailed introduction of five common breeding methods of Phalaenopsis

Phalaenopsis is a common orchid plant, which has high ornamental value and certain decorative function. It is often used to decorate gardens, courtyards and studies. So, do you know the breeding methods and precautions of Phalaenopsis? Today, the editor will introduce it to you in detail. Let's study with the editor.

I. method of sowing and breeding

This method can breed a large number of excellent seedlings, and is not easy to transmit viruses and other diseases, but also can use the means of hybridization to cultivate new varieties with better, more novel and more colorful patterns.

1. Natural sowing method

The seeds from the dehiscent capsule are sown in the flowerpot of the parent plant, because there may be symbiotic bacteria necessary for Phalaenopsis seed germination in the plant material of the parent plant. The natural sowing method is simple and easy, does not need complex aseptic procedures and operating tools, and is suitable for ordinary family Phalaenopsis growers, but this method has little chance of success and is rarely used.

2. Aseptic sowing method

The method is to rinse the uncracked mature capsule, then soak it in 75% 90% ethanol or chloroform for 2 seconds, and then soak it in 5% 10% bleach solution or 3% hydrogen peroxide for 5 minutes for 20 minutes. Take out the seeds and soak them in the same disinfectant for 5 minutes, then remove the solution by filtration, take out the seeds, and spread the seeds evenly on the surface of the culture medium in the prepared bottle with fine needles. The culture conditions were as follows: light intensity 2000-3000 lux, 10-18 hours a day, and the temperature was kept at 20-26 ℃. After 9-10 months, the seedlings can grow 2-3 leaves and then be planted in pots. This method is a scientific work, which is generally carried out in a tissue culture laboratory or in a large-scale and strictly managed tissue culture factory.

2. Pedicel budding and reproduction

After the flowers of many varieties of Phalaenopsis wither, young seedlings with roots can often grow on the internodes of their pedicels, which can be cut off and planted separately to grow into a new Phalaenopsis. The method of artificial budding can be used to ensure that the pedicels of Phalaenopsis grow into pedicel seedlings for reproduction. The method is to first cut off the flowering part of the pedicel, and then carefully remove the bracts of the first to third internodes in the upper part of the pedicel with a blade or sharp blade to expose the bud points in the internodes; apply hormones such as budding agents or indolebutyric acid evenly on the exposed Internode nodes with cotton swabs After treatment, the orchid plant was placed in a semi-shade place, and the temperature was kept at 25: 28 ℃. After 2 weeks, the buds grew into leaves, and after 3 months, they grew into Phalaenopsis seedlings with 3 leaves and aerial roots. cut off the seedlings and put them on the pot, they can become a new orchid plant.

Third, the method of broken heart and accelerating germination and reproduction.

After the growth point of the orchid plant was destroyed due to freezing injury, insect pests, diseases and man-made factors, 1 or 2 new buds will grow from the stem nodes near the base of the orchid plant after a period of time. This feature can be used to breed Phalaenopsis. The specific method of operation is to remove the highest heart leaf from the top of the stem, and pay attention to destroying the growth point of the stem tip so that it cannot grow upward; the wound is dried or sterilized with fungicides, after a period of time, 2 or 3 new buds can grow on the stem nodes near the base; when the new buds grow and the roots grow out of the base, they can be cut off and planted as a new plant.

IV. Stem cutting and breeding

The principle of stem cutting and reproduction is to destroy the growth point of stem tip to induce latent bud growth. Although there are 1-3 latent buds in the axils of Phalaenopsis plants, most of them can not sprout into plants. After the plant continues to grow upward and the stem node is longer, the upper part of the plant with root is cut off with a sterilized knife or scissors, implanted into a new basin to make it continue to grow, and the lower part of the rhizome is given proper water management. three new buds can be sprouted soon (depending on the characteristics and management methods of the plant). If the stem of the plant is longer, it can also be considered to cut into multiple segments, as long as each segment has 2-3 internodes or more than 2-3 cm long and more than one root, it is possible to grow into a new plant, but if the rhizome of the plant has dried up and died, then this method is ineffective.

5. Tissue culture method

The excellent genetic characteristics of Phalaenopsis can be obtained by using tissue culture to propagate Phalaenopsis. The butterfly orchid seedlings produced by this method are called meristem or tissue seedlings. The plant tissues (explants) used for meristematic culture can be terminal buds (stem tips), stem segments (dormant buds), young leaves or root tips, but at present the most common is the pedicel of Phalaenopsis. Because the selection of pedicel as explant, not only will not damage the plant, but also easy to induce. Older pedicels or flowering pedicels mainly take peduncle node buds, while young pedicels can also be used as culture materials in addition to pedicel node buds.

That's all I know about Phalaenopsis today. I hope it will be helpful for you to read this article. If you want to know more about Phalaenopsis, please continue to pay attention to the succulent flower bed, we will provide you with more related knowledge!

There are five main propagation methods of Phalaenopsis: sowing propagation, pedicel budding propagation, heart-breaking propagation, stem-cutting propagation and tissue culture. First, the method of sowing and propagation can produce a large number of excellent seedlings, and it is not easy to transmit viruses and other diseases, and it can also be used to cultivate new varieties with better, more novel and more colorful patterns by means of hybridization. The main results are as follows: 1. In the natural sowing method, the seeds from the cracked capsule are sown in the flowerpot of the parent plant, because there may be symbiotic bacteria necessary for the germination of Phalaenopsis seeds in the plant material of the parent plant. The natural sowing method is simple and easy, does not need complex aseptic procedures and operating tools, and is suitable for ordinary family Phalaenopsis growers, but this method has little chance of success and is rarely used. 2. The aseptic sowing method is to wash the uncracked mature capsule, then soak it in 75% 90% ethanol or chloroform for 2 seconds, and then soak it in 5% 10% bleach solution or 3% hydrogen peroxide for 5 minutes for 20 minutes. Take out the seeds and soak them in the same disinfectant for 5 minutes, then remove the solution by filtration, take out the seeds, and spread the seeds evenly on the surface of the culture medium in the prepared bottle with fine needles. The culture conditions were as follows: light intensity 2000-3000 lux, 10-18 hours a day, and the temperature was kept at 20-26 ℃. After 9-10 months, the seedlings can grow 2-3 leaves and then be planted in pots. This method is a scientific work, which is generally carried out in a tissue culture laboratory or in a large-scale and strictly managed tissue culture factory. Pedicel bud propagation method after the flowers of many varieties of Phalaenopsis wither, young seedlings with roots can often grow on the internodes of the pedicels, which can be cut off and planted separately to grow into a new Phalaenopsis. The method of artificial budding can be used to ensure that the pedicels of Phalaenopsis grow into pedicel seedlings for reproduction. The method is to first cut off the flowering part of the pedicel, and then carefully remove the bracts of the first to third internodes in the upper part of the pedicel with a blade or sharp blade to expose the bud points in the internodes; apply hormones such as budding agents or indolebutyric acid evenly on the exposed Internode nodes with cotton swabs After treatment, the orchid plant was placed in a semi-shade place, and the temperature was kept at 25: 28 ℃. After 2 weeks, the buds grew into leaves, and after 3 months, they grew into Phalaenopsis seedlings with 3 leaves and aerial roots. cut off the seedlings and put them on the pot, they can become a new orchid plant. 3. After the growth point of the flange plant was destroyed due to freezing injury, insect pest, disease and man-made factors, 1 or 2 new buds will grow from the stem node near the base of the orchid plant after a period of time. This feature can be used to breed Phalaenopsis. The specific method of operation is to remove the highest heart leaf from the top of the stem, and pay attention to destroying the growth point of the stem tip so that it cannot grow upward; the wound is dried or sterilized with fungicides, after a period of time, 2 or 3 new buds can grow on the stem nodes near the base; when the new buds grow and the roots grow out of the base, they can be cut off and planted as a new plant. 4. The principle of stem-cutting propagation is to destroy the growth point of stem tip to induce latent bud growth. Although there are 1-3 latent buds in the axils of Phalaenopsis plants, most of them can not sprout into plants. After the plant continues to grow upward and the stem node is longer, the upper part of the plant with root is cut off with a sterilized knife or scissors, implanted into a new basin to make it continue to grow, and the lower part of the rhizome is given proper water management. three new buds can be sprouted soon (depending on the characteristics and management methods of the plant). If the stem of the plant is longer, it can also be considered to cut into multiple segments, as long as each segment has 2-3 internodes or more than 2-3 cm long and more than one root, it is possible to grow into a new plant, but if the rhizome of the plant has dried up and died, then this method is ineffective. 5. tissue culture method Phalaenopsis can be propagated by tissue culture method, which can obtain the same excellent genetic characteristics as the mother plant. The butterfly orchid seedlings produced by this method are called meristem or tissue seedlings. The plant tissues (explants) used for meristematic culture can be terminal buds (stem tips), stem segments (dormant buds), young leaves or root tips, but at present the most common is the pedicel of Phalaenopsis. Because the selection of pedicel as explant, not only will not damage the plant, but also easy to induce. Older pedicels or flowering pedicels mainly take peduncle node buds, while young pedicels can also be used as culture materials in addition to pedicel node buds.
