The invention provides an in-vitro quick propagation method for acanthopanax gracilistylus. The large-scale production and propagation are executed to meet a market requirement. Acanthopanax gracilistylus tissue culture steps comprise: A, disinfecting an explant; B, obtaining germfree seedlings; C, growing and culturing axillary buds; D, inducing cluster buds; E, performing rooting culture; and F, performing seedling hardening and transplanting. According to a plant tissue culture method for propagating the acanthopanax gracilistylus, the influence caused by the external conditions is avoided, and the method can be performed in four seasons; the land occupied by seedlings is saved, and the production cost is lowered; furthermore, all good characters of a parent can be stored, and the inheritable character is stable. The method can be used for forming a large number of high-quality test tube seedlings within short time; the large-scale and industrial production is realized, and a large quantity of raw materials can be supplied to the industries such as ornamental horticulture and pharmacy.

The present application belongs to the technical field of plant genetic engineering, and specifically relates to the cloning, functional identification and an application of a key dominant gene WhiteKale Locus 1 (WKL1) which controls the low-temperature albino of white kale. A nucleotide sequence of the gene is shown in SEQ ID NO: 1. The invention also relates to a promoter of the WKL1 gene and the cloning of its recessive allele promoter. Through the agrobacterium-mediated transformation of Solanaceae tobacco and green cabbage, the functional verification shows that the gene has the significant function to control the albino of white kale at low temperature. The discovery of the KWL1 gene provides new genetic resources for the production of new white ornamental varieties in cruciferous vegetables, and provides new genetic resources for ornamental horticulture. The utilization of the resource is conducive to the cultivation of new ornamental plant varieties.

The invention belongs to the technical field of plant genetic engineering, and specifically relates to a gene related to dormancy relief of bulbous flowers and its application. The gene is DRR1 Gene, DRR1 The nucleotide sequence of the gene is shown in SEQ ID NO:1. The present invention also relates to DRR1 Cloning of the promoter of the gene. Through the phenotypic analysis of Agrobacterium-mediated stable transformation of Arabidopsis plants, the results showed that the gene has significant functions of replacing low temperature to break plant dormancy, regulating seed germination and flower bud growth. DRR1 The discovery of the gene provides new genetic resources for the cultivation of new varieties of lily bulbs that do not require low temperature treatment or low temperature requirements; at the same time, it provides new genetic resources for ornamental horticulture. The use of this gene greatly shortens the growth cycle of bulbous flowers , which reduces the economic cost of bulb post-harvest treatment and promotion of cultivation.

The invention discloses a simplified pest control method used for facility potted flower production, and belongs to the technical field of ornamental horticulture pest prevention and control. A simplified pest control mode including the first step of facility condition strengthening, the second step of healthy cultivation, the third step of dispelling, the fourth step of induction and control, the fifth step of biocontrol object release and the sixth step of pesticide application is established for piercing-sucking and rasping-sucking pests such as thrips, kanazawa spider mites, aphid, whiteflies and stem and leaf diseases such as black spot, anthracnose, damping-off, southern blight and stalk rot in the whole process of facility potted flower production, the operation is easy, standard, safe and efficient, use of chemical fertilizers and pesticides is remarkably reduced while diseases and pests in the whole process of facility potted flower production can be effectively controlled, and application reduction and effect improvement of the chemical fertilizers and the pesticides are achieved.

The invention relates to a clivia pseudo-bulb cuttage propagation method and belongs to the fields of plant cultivation technology, landscape plant and ornamental horticulture. The method comprises mixing turfy soil, perlite and leaf mould at a certain proportion into the culture medium for cuttage propagation of clivia pseudo-bulb; putting the culture medium into a seedling raising plate through appropriate pH value adjustment; cutting clivia pseudo-bulb slices into the culture medium after sterilization and rooting, and providing an appropriate temperature and humidity environment for the clivia pseudo-bulb slices; after the cut clivia pseudo-bulb slices sprout roots, transplanting and culturing the clivia pseudo-bulb slices under greenhouse conditions through regular management methods into normal clivia plants. According to the clivia pseudo-bulb cuttage propagation method, by means of cuttage propagation, the sliced clivia pseudo-bulb can be in an excellent growth environment, thereby effectively improving the growth by differentiation and the propagation rate.

The invention provides a simplified disease and pest control method for sansevieria trifasciata facility planting and relates to the technical field of disease and pest prevention and control in ornamental horticulture. For two stages of a facility planting process of sansevieria trifasciata, the method establishes a whole set of simplified disease and pest control modes including disinfection, improvement and change, timely management and prevention for field cultivation raising and simplified disease and pest control modes including adjustment, disinfection and control for pot culture raising. The operation is simplified, standardized, safe, efficient, labor-saving, effort-saving, and time-saving; the method can effectively control the occurrence and damage of diseases and pests in the facility planting process of sansevieria trifasciata, remarkably reduce the use of chemical fertilizer and pesticides, and realize application reduction and effect increase of chemical fertilizer and pesticides, and is of great importance for the green production of sansevieria trifasciata and environmental protection.

The invention belongs to ornamental horticultural seedling raising technology, in particular to a method for quickly releasing dormancy of sweet-scented osmanthus seeds. The steps include: from late April to late May, when the sweet-scented osmanthus fruit turns blue-purple, harvest, remove the pulp, clean and dry the seeds; pick out a large, plump, pest-free seed, and use permanganate Soak in potassium solution for 30 minutes, pour off the solution and suffocate for 10 minutes, wash the seeds and dry them; rub the two ends and four sides of the osmanthus seeds with sandpaper; soak the mechanically treated seeds with a mixed solution of gibberellin and lanthanum nitrate; Mix the soaked seeds with wet sand, put them into a container, cover the surface with plastic wrap, punch holes, and carry out low-temperature stratification. The operation method of the invention is simple and easy, has low cost and high germination rate, and is suitable for both test and production needs.

The invention provides a method for mass propagation of lycoris aurea through somatic embryogenesis. The lycoris aurea tissue culture method for scale production and propagation so as to meet the market demand comprises the steps of A, explant disinfection, B, adventitious bud induction, C, callus induction, D, callus propagation, E callus redifferentiation, F, rooting culture, and H, seedling exercising and transplanting. According to the method, herbicide picloram is applied to tissue culture of lycoris aurea for the first time, stable lycoris aurea tissues capable of being propagated on a large scale are obtained, the callus induction rate reaches 95% or above, and the propagation coefficient of the lycoris aurea is at least increased by 8-10 times. The production cost is reduced, furthermore, the whole fine properties of a parent body can be preserved, and the inheritable character is stable. Through the method, a large number of excellent test-tube seedlings can be formed within a short period of time, large-scale industrialized production is conducted, and a lot of raw materials are provided for ornamental horticulture, pharmacy and other industries as well as the follow-up study of the lycoris aurea.
