Embodiment 1

[0016] Embodiment 1 The present invention improves a method for the seedling rate of pitaya tissue culture seedlings, and its steps are as follows:

[0017] (1) Adventitious bud induction

[0018] ① Selection and treatment of explants: select semi-lignified dragon fruit stems that are free from diseases and insect pests, wash them with washing powder water first, and rinse them with tap water, then cut the stems longitudinally, remove the pith, and then cut into Stem slices with a width of 2cm to 3cm and a length of 3cm to 4cm. The outer skin of each stem slice has a complete thorn seat, and the fluff and small thorns on the thorn seat are retained.

[0019] ② Adventitious bud induction: Disinfect the treated stem slices in 75% alcohol for 30 seconds, wash once in sterile water, transfer to 2% sodium hypochlorite solution for disinfection for 10 minutes, and then sterilize them in sterile water. Wash 3 to 5 times, after the disinfection is completed, cut off the surface of th...

Embodiment 2

[0026] Embodiment 2 is the same as Embodiment 1 except that the following measures are different, and will not be repeated here.

[0027] The adventitious bud induction medium of step (1) ② is: MS+TDZ0.4mg / L+NAA0.1mg / L+sucrose 3%+agar 0.6%, pH value is 5.8; The seedling growth medium of step (2) is: MS+6-BA4mg / L+NAA0.1mg / L+activated carbon 1g / L+sucrose 3%+agar 0.6%, pH value is 5.8.

[0028] The test effect of above each embodiment:

[0029] Pitaya tissue culture seedlings become seedlings: refer to the main stem with basal roots and / or the side shoots with aerial roots of the adventitious buds that are inserted into the above-mentioned seedling medium to proliferate (promptly grow out).

[0030] These main stems with basal roots and side branches with aerial roots have roots, stems, and leaves (the small thorns of dragon fruit are its leaves, which are metamorphic leaves), and they become complete regenerated plants after being cut off respectively. .

[0031] The seedling...

Abstract

The invention provides a method for improving the seedling rate of tissue culture seedlings of hylocereus undulatus britt. The method comprises the following steps: carrying out adventitious bud induction, synchronous multiplication and rooting seedling culture, wherein hylocereus undulatus britt barbed seats and lignification shoots with small barbs and fluff on the barbed seats are used as explants; when lateral branches of adventitious buds grow, base roots of adventitious bud base parts grow and aerial roots of the lateral branches grow, carrying out hardening seedling; after the hardening seedling, taking out seedlings from a bottle; cutting off the lateral branches with the aerial roots and main stems with the base roots and planting in a culture medium; after the lateral branches and the main stems are survived, growing new roots; and putting the lateral branches and the main stems into pots. According to the method, the production period of the tissue culture seedlings of the hylocereus undulatus britt is short, the adventitious bud induction rate is high, the multiplication and the rooting are synchronous, the multiplication coefficient is more than 5.45 and the rooting rate is 100%; the growth vigor of multiplied seedlings is strong and the transplanting survival rate is more than 95%; one inoculated adventitious bud can grow 3-4 lateral branches with the aerial roots, namely one inoculated adventitious bud can grow 4-5 grown-up seedlings with the roots; the seedling rate of the tissue culture seedlings of the hylocereus undulatus britt is increased by 3-4 times.

Description

technical field [0001] The invention belongs to the technical field of plant propagation, and in particular relates to a method for improving the seedling rate of dragon fruit tissue culture seedlings. Background technique [0002] Pitaya scientific name (Hylocereus undatus (Haw.) Britt. & Rose.), also known as red dragon fruit, green dragon fruit, fairy honey fruit, etc., is a plant of the genus Hylocereus (Cactaceae) in the family Cactaceae. The fruit of dragon fruit is not only beautiful in appearance, but also has a health care effect. It has the effects of clearing blood, reducing fire and lowering cholesterol. Regular consumption can promote human metabolism and improve immune function. In addition, its cultivation is relatively easy, with few pests and diseases, early fruit and high yield, and can adapt to drought Climate is a new type of fruit with great potential for market development. In recent years, Yunnan, Guizhou, Guangxi, Guangdong and other provinces are vi...
