Propagation is the increase in the number of plants for flowering plants to propagate by seeding and cutting various parts. of Lam Tan
Seed propagation It's easy to do, but growers need to know that if they keep seeds for planting without knowing how to pick them, they'll be able to pick them up. The resulting new plant usually does not retain the outstanding characteristics of the parent plant, as the seeds are obtained by mixing male and pistils. They all have a lot of trait control genes. When paired again, it results in a different appearance. We call it a mutation, and it often turns worse than the mother plant. Seeds produced commercially and classified as of good quality must meet the varieties. It has a high percentage of germination. When germinated, give healthy seedlings and no diseases attached to the seeds. Examples of species matches are: If, according to the catalog, Zinnia varieties Polar Bear have very large flowers. Diameter 6 inches Pure white color, the petals are tightly stacked, making the flowers up to 4 inches thick. From the color, flower size, and thickness of the flower, any company that produces seeds that the buyer uses and is disappointed. Because the quality is not as good as advertised, they will stop buying from that company. Therefore, seed production is a competing undertaking both domestically and internationally. Because buyers have the opportunity to choose what they like.
In general, seed production requires plant breeders to select and control pollination. Between the father tree and the mother tree to give the desired appearance. Especially if it is the seed of the 1st evil hybrid (F1 hybrid, F is from FIRIAL. It has the distinctive feature is that the plant of uniform height blooms at the same time. It gives good color, and some species may give flowers faster than ordinary varieties, but seeds collected from F1, namely F2, are inferior in appearance to F1. Until it is not recommended to keep it for the next generation. For example, the F1 hybrid seeds of the Climax marigold variety produce large yellow flowers. Size 5 inch The petals stack so much that they look round like balls. As far as F1 seeds were collected and seeded in 800 F2 trees, only 1 was the same. That one still has marigolds with double petals, round flowers like the mother's generation. Other than that, the flowers are reduced to only 3 and a half inches. There are much fewer petals. This makes the flowers flat, not beautiful at all. Waste of labor, waste of time. Since the season to plant flowers is very beautiful in a year, there is only one time.
Incidentally, if it is not a hybrid seed (there is no word hybrid preceding or after the flower name on the seed envelope). Will collect sensitive seeds available. To produce seeds, the planting site must not contain similar plant varieties. If so, it must be at least 200 meters away to prevent crossing. The characteristics of your generation may be somewhat different from your mother's generation, but not so much. Some species do not change at all. Seed collection is done by storing the aged seeds in the sun for 1-2 suns and then drying them indoors. Because the flower seeds are usually dark and mostly small. Sunny-outdoor in Thai weather It can cause the seeds to die or lose germination. A simple test of how dried the seeds is done is to put them in a plastic bag and close them tightly. If there is no fog, steam occurs in the bag, it is fine. Storing seeds in tightly closed containers in a cool and dry place will be stored for up to a year. In trade, producers reduce the moisture content of the seeds to 5-10%, and then pack them in containers that protect them from temperature changes. and the transfer of moisture from outside air into the seeds, such as tin cans or pouches made of aluminum foil. If the buyer has opened it and used it all, it should be sealed tightly and stored in a cool place. If there is a refrigerator, it should be placed in the vegetable compartment (the temperature is about 4 ° C). Old or new, poorly stored seeds lose a lot of germination or germinate, and then acquire unhealthy seedlings. When choosing to buy seeds, it is better to choose new seeds. If the seed pouch is made of aluminum foil, even better.
There are two ways to plant seeds: directly in the plot and in greenhouses.
Direct sowing in the planting plot is usually used for large grains, which, when the seedlings germinate, grow quickly. It can fight outdoor environments. This method has the advantage of not stalling seedlings due to transplanting. This makes flowering faster. Growing seedlings in greenhouses Use with very small or expensive seeds. Growers do not want to risk sowing directly on the plot, where the seeds may be subjected to heavy rainfall. The hot sun prevents the seeds from germinating. Seedlings obtained from this type of seeding may have a period of stagnation when transplanting out of the plot. But growers help by transplanting seedlings when they are not very mature and scooping up a lot of soil covering the roots. Keep the plant affected to a minimum. The soil used for planting small seeds should retain moisture well. Good water drain and airy There is some organic matter. Examples of planters used are 1 part soil, 1 part sand, 1 part old manure, rice husk ash. 1 Mix well.
Propagated by cuttings
Propagated by cuttings of different parts. of the stem is achieved because the plant has the ability to create that deficiency to get a new one. One plant consists of a plant and a root. We can cut the cuttings and get new roots. If the root is cut to cuttings. The buds at the root can be born as new plants, or when the leaves are cut for cutting, they can be both new plants and roots. However, plants have different abilities to create replacement parts. Not all plants can be propagated by cuttings, for example, flourishing old cuttings get new ones in no time. But the sky-wide can't cut leaves. While many flowering plants can be reborn by cutting leaves, such as African violet. Glock Zenia Knowing the types of plants and specific ways to propagate them can be very useful.
1. Cuttings
Cut the branches into pieces and cut the branches that can be divided according to the age of the wood. as follows Cuttings old branches are branches that are 1 year old or older. The wood is brown and has no sticking leaves. If broken, you can feel the hardness of the wood. Cut the old branches into pieces, about 1 creep long, and then take the cuttings. Remove the embroidered cones into the cuttings material. An example of a plant that can grow old cuttings is Bodhi Daeng. Candle drops, bamboo, roses used to make rootstocks. bougainvillea Cuttings of semi-old, semi-young branches, i.e. branches that have been growing for 1 season, have a greenish-brown color with stuck leaves. For example, hibiscus. Fuengfah jasmine rabbit ears Snakehead ears, Garuda nails Some varieties of pine spruce Young cuttings include newly broken apical branches. It has a light green color. The wood is still soft with many attached leaves, such as roses. Song of Jamaica (leafy plant) Cuttings of young shrub shoots are cutting shoots about 3-5 inches long to cuttings, removing some of the lower leaves. Examples of softwood shrubs are chrysanthemums, hydrangeas, carnations, geraniums, mixed hermits, dahlias, and rattle.
2. Leaf cuttings There are several varieties.
Leaf plate cuttings by cutting the leaf plates into pieces or pieces and then cuttings such as aloe vera. Begonia
Take both the leaf and the stem and pin the base of the petiole into the cuttings material, such as African violet. Peperomia Glokxenia Apasia
Leaf cuttings stick to the petiole and slash the bud at the base of the petiole attached. This method is used on plants that can take root. But they can't be born new trees, so they take their eyes with them to make them grow, etc., such as Indian rubber. chrysanthemum
Cuttings by cutting the leaf veins. Use a knife to cut the middle line of the leaf at regular intervals. Then place the leaf plates tightly against the cuttings to always get moisture, or use a small stick to fix the leaves to attach to the planter. This method obtains several plants from one leaf. New plants are formed at the cut of the mid-leaf line, such as begonia.3. Root cuttings are a viable but unpopular method.
Because plants that can be propagated in this way can also be used cuttings, cuttings or cuttings. And it's more convenient to get a new plant sooner. Root cuttings need to dig out the roots and cut them into pieces. Place the root pieces horizontally with the planter for about 2 months. For example, a rainbow. needle Flox Statis The material from which the cuttings are used should be airy, but retain moisture well, such as sand and ash of old rice husks. Mix well and keep the moisture evenly until the roots are removed.
