The flower of Dendrobium primulinum is full of charm, the petal color is lavender, the lip is white, the peduncle and the ovary are yellow-green. In spite of its beauty, it mainly blooms from March to April. That is to say, only in spring can we appreciate its charm. It is mainly propagated by tissue culture. Here's the steps of the tissue culture propagation method of Dendrobium primulinum.
This is mainly about the way of tissue culture. Normally, seeds are hard to come by, and artificial pollination does not preserve the mother's benefits. Therefore, tissue culture is an effective method.
A dendrobium dendrobium with normal growth and development was selected, and its tender stem segments with five or six segments were selected. Rinse them under running water for about an hour, then remove all the leaves and cut them in half. Once cut, soak in 70 percent alcohol for about half a minute, and then sterilize in raw mercury for six minutes. Next, after rinsing the stem several times with sterile water, the leaf sheath is removed and the stem is disinfected with raw mercury for three minutes. Then rinse with water, and then dry with paper. It is best to choose a special absorbent paper, and the water mentioned above is aseptic. Finally, cut off the knobbly stem segments and tips, about a centimeter or so.
Place the above stem segments and tips on the medium and wait for their lateral buds to begin to germinate (approximately 18 days should be observed). When the terminal and lateral buds are about one centimeter long, the young buds are cut off and transferred to another medium. After about three weeks, the buds will be about two centimeters long and the leaves will have two or three pieces.
This step is to first choose the best development, the most robust bud bud proliferation. After that, if the bud reaches about three centimeters in length, it can be induced. After a period of culture (about twenty days), about two or three roots will grow, and you will have a complete plant. And then you let it continue to grow, and when you get to two or three meters, and the root system is almost strong, you take it out of the culture medium, you put it in a greenhouse, and you're done.
