Propagation and Seedling of Longevity Flower

Longevity flowers mostly use the method of asexual reproduction, in addition to cutting, but also use tissue culture to propagate. There are two ways of cutting: leaf cutting and terminal bud cutting. Leaf cutting and tissue culture are mostly used for the production of female parent seedlings, and terminal bud cuttings are mostly used for potted flower production.

Potted flower production-the rootless cuttings are cut directly in the flowerpot where they will eventually be planted, so the cultivation medium and cutting substrate are the same, mixed with peat and perlite in the ratio of 7 ∶ 3, and the ph value of the substrate is adjusted to 5.5 to 6.0. Producers can adjust the proportion according to water quality, production variety and production season, or add soilless substrates such as vermiculite and sand to become a matrix with good drainage and moderate nutrients.

L, leaf cuttage. Take off the whole leaf (the bigger the leaf, the better) and leave it in a cool place to dry the injured □. After a few hours, the petiole is completely inserted into the moist substrate. If the petiole is too short, the part of the leaf can also be inserted into the matrix to replace the short petiole. Don't get too wet at this stage, lest the leaves get sick and rot.

After cutting, put it in a slightly weaker part of the sun and keep the temperature between 20 degrees Celsius and 25 degrees Celsius. The root system begins to be established after 4 weeks, when it can be put under full-day sunshine and low concentration of fertilizer can be applied. After 7~l0 weeks, the seedlings differentiated from callus can be seen. When the seedlings grow to 15-20 cm, they can be raised separately from the leaves, and the leaves can continue to produce seedlings. Separate seedlings can be used as female parent seedlings to produce rootless cuttings.

2. Terminal bud cuttage. The top bud of the prepared branch is directly inserted into the flowerpot equipped with the substrate to keep the substrate moist, the light intensity should not be too strong, and the temperature should be kept between 20 degrees Celsius and 25 degrees Celsius, which can take root in about 2 to 3 weeks. then you can enter the production period for management. Terminal bud cuttings are often used in potted flower production (note: longevity flowers are typical plants that bloom in long days, during cutting propagation-make sure the sunshine time is longer than 12.5 hours, and replenish light when cutting propagation in winter).

The method of asexual propagation is often used in the propagation of longevity flowers, and tissue culture is often used in addition to cuttings. There are two ways of cutting: leaf cutting and terminal bud cutting. Generally, leaf cutting and tissue culture are mostly used for the production of female parent seedlings, and terminal bud cuttings are mostly used for potted flower production. In potted flower production, rootless cuttings are usually cut directly in the flowerpot where they will eventually be planted, so the cultivation medium is the same as the cutting substrate, which is mixed with peat and perlite in the ratio of 7 ∶ 3, and the pH value of the substrate is adjusted to 5.5 to 6.0. Producers can adjust the proportion according to water quality, production variety and production season, or add soilless substrates such as vermiculite and sand to become a matrix with good drainage and moderate nutrients. 1. Leaf cuttage. Take off the whole leaf (the bigger the leaf, the better) and dry the wound in a cool place. after a few hours, the petiole is completely inserted into the moist matrix. If the petiole is too short, a part of the leaf can be inserted into the matrix instead of the short petiole. Don't get too wet at this stage, lest the leaves get sick and rot. After cutting, put it in a place with less sunlight and the temperature was kept between 20 ℃ ~ 25 ℃. The root system begins to be established after 4 weeks, when it can be put under full-day sunshine and low concentration of fertilizer can be applied. The seedlings differentiated from callus can be seen after 7 weeks and 10 weeks. When the seedlings reach 15~20cm, they can be cultivated separately from the leaves, and the leaves can continue to produce seedlings. Separate seedlings can be used as female parent seedlings to produce rootless cuttings. 2. Terminal bud cuttage. The apical buds of the prepared branches were directly inserted into the flowerpot with the substrate installed, keeping the substrate moist, the light intensity should not be too strong, and the temperature should be kept between 20 ℃ and 25 ℃, and it could take root in about 2-3 weeks, and then it could be managed during the production period. Terminal bud cuttings are generally used for potted flower production (note: longevity flowers are typical plants that bloom in long days, sunshine time must be longer than 12.5 hours during cutting propagation, and light must be replenished when cutting propagation in winter). Asexual culture of longevity flowers mostly adopt the method of asexual culture, and tissue culture is more often used in addition to cutting. There are two ways of cutting: leaf cutting and terminal bud cutting. Generally, leaf cutting and tissue culture are mostly used for the production of female parent seedlings, and terminal bud cuttings are mostly used for potted flower production. In potted flower production, rootless cuttings are usually cut directly in the flowerpot where they will eventually be planted, so the cultivation medium is the same as the cutting substrate, which is mixed with peat and perlite in the ratio of 7 ∶ 3, and the pH value of the substrate is adjusted to 5.5 to 6.0. Producers can adjust the proportion according to water quality, production variety and production season, or add soilless substrates such as vermiculite and sand to become a matrix with good drainage and moderate nutrients.

(1) Leaf cutting. Take off the whole leaf (the bigger the leaf, the better) and dry the wound in a cool place. after a few hours, the petiole is completely inserted into the moist matrix. If the petiole is too short, a part of the leaf can be inserted into the matrix instead of the short petiole. Don't get too wet at this stage, lest the leaves get sick and rot. After cutting, put it in a place with less sunlight and the temperature was kept between 20 ℃ ~ 25 ℃. The root system begins to be established after 4 weeks, when it can be put under full-day sunshine and low concentration of fertilizer can be applied. The seedlings differentiated from callus can be seen after 7 weeks and 10 weeks. When the seedlings reach 15~20cm, they can be cultivated separately from the leaves, and the leaves can continue to produce seedlings. Separate seedlings can be used as female parent seedlings to produce rootless cuttings. (2) terminal bud cuttage. The apical buds of the prepared branches were directly inserted into the flowerpot with the substrate installed, keeping the substrate moist, the light intensity should not be too strong, and the temperature should be kept between 20 ℃ and 25 ℃, and it could take root in about 2-3 weeks, and then it could be managed during the production period. Terminal bud cuttings are generally used for potted flower production (note: longevity flowers are typical plants that bloom in long days, the sunshine time must be longer than 12.5 hours during cutting culture, and light must be replenished when cutting culture in winter).
