Description

Efficient propagation method of ilex verticillata
Technical Field
The invention belongs to the vegetative propagation technology of woody plants, and particularly relates to a high-efficiency propagation method of ilex verticillata.
Background
Ilex verticillata (L.) a.gray) is Ilex deciduous shrub of genus Ilex (Ilex) of family Aquifoliaceae (Aquifoliaceae). Native northeastern America is loving yin and dampness, resistant to drought, strong in resistance and wide in adaptability. After leaves of ilex verticillata fall in winter, bright red and dense fruits are full of branches and are commonly used as branch-cut fruits, pot culture, hedgerow, block planting, water bank greening and the like in countries such as Europe and America, the ornamental characteristics of the hot festival are in accordance with the traditional festival culture of China, and a large number of branches need to be imported from abroad every year to meet the market of China.
More than 10 varieties such as Ilex verticillata 'Oosterwijk' and the like are introduced from the United states and the Netherlands in 2006 in China, wherein the varieties such as 'Oosterwijk', 'Maryland Beauty', 'Winter Red' and 'Winter Gold' have good growth performance, but the propagation rate is low, and the growth is slow, so that the popularization and the application of the North American holly are restricted.
Through literature and research, the propagation method of the ilex verticillata is only limited to cuttage and tissue culture, the cutting result of 'Oosterwijk' hard branches is reported by Chenhuiying (2015), and the rooting rate is 82% when the base of the branches are subjected to cuttage in autumn; the Oosteerwijk' twig cutting technology is researched by a residual auspicious test (2015), the highest survival rate of the non-lignified twigs can reach 88.4%, and the rooting rate of the lignified twigs is only 55.56%; duckweed (2015) was also studied in North America ilex cutting propagation and tissue culture. The above experimental studies show that: the tissue culture technology of the ilex verticillata is high in cost and is immature; the conventional cutting propagation method of the ilex verticillata is difficult to root, the rooting rate is low, the time required for rooting is long, meanwhile, the cutting seedlings need to grow for more than 3 years, blossom and bear fruits, and the popularization and the application of the ilex verticillata are greatly influenced.
China is a main distribution area of ilex plants, wherein ilex latifolia (I. macrocarpa Oliv.) and ilex verticillata are deciduous tree species, the relativity is close, and the grafting and breeding survival rate is high. In recent years, the applicant develops the grafting propagation test of the improved variety of the ilex verticillata by utilizing the advantages of abundant ilex resources in China and taking the ilex macrocarpa as a stock, and obtains good effect. The method breaks through the difficulty of rapid seedling formation of the improved variety breeding of the ilex verticillata, realizes grafting and outplanting for sale in the current year, can bloom and bear fruits in the next year, and promotes the market popularization and garden application of the improved variety of the ilex verticillata.

(6) And (4) management after connection: after grafting, the nursery land is kept moist, the scion buds germinate within 10-15 days, the buds on the rootstock are removed in time, the growth and development of the scion are promoted, and when the young shoot of the scion grows to about 30cm, the scion needs to be inserted and protected to prevent wind break. And the water and fertilizer management is enhanced, and the plant diseases and insect pests are prevented and treated in time.
2. The method for efficiently propagating ilex verticillata according to claim 1, wherein the method comprises the following steps: step (4)) The plant growth regulator is GGR 100-150 mg.L-1An aqueous solution of (a).
Advantageous effects
The ilex verticillata and the ilex macrocarpa are both ilex varieties, the genetic relationship is very close, the scion of the ilex verticillata is treated by exogenous hormone by utilizing the characteristic of high affinity between the same species and the same species of plants, the callus at the grafting part is further promoted to be rapidly generated, the ilex macrocarpa transfers nutrients to the scion of the ilex verticillata for rapid growth by relying on root transmission power, the propagation cycle of seedling culture such as cutting of the ilex verticillata is shortened, and the purpose of grafting and outplanting in the same year can be realized; the grafting propagation method can keep the ornamental characteristic of the North America holly, has low propagation cost and simple and convenient operation, and has higher popularization value in the rapid propagation of the ornamental seedlings of the North America holly.
