Abstract
A tissue culturing method for quercus virginiana belongs to plant tissue culturing methods and is characterized by comprising the following steps: 1 selecting of explants; 2 disinfection of the explants; 3 primary culture; 4 multiplication culturing of adventitious buds; 5 culturing of strong seedlings; 6 culturing of strike roots; and 7 seedling acclimatization and transplanting. The tissue culturing method for the quercus virginiana can keep stress resistance and enjoyment of a female parent and can effectively increase propagation coefficient of the quercus virginiana. Compared with seminal propagation, tissue culturing reduces dependency on imported seeds, can effectively reduce nursery stock cost, and saves expenditures. Compared with cutting propagation, the tissue culturing is short in seedling culturing period, can obtain the nursery stock with strike roots within 4 months, and saves cost.
Description
Technical field
The invention belongs to method for plant tissue culture, be specially a kind of tissue culturing method for quercus virginiana.
Background technology
Virginia oak (
Quercus virginiana)Belong to Fagaceae (Fagaceae) oak and belong to (Quercus) seeds, originate in the U.S., be the high megaphanerophyte of evergreen broad-leaved.Single leaf, alternate, the Lao Ye keratin, leaf surface bottle green tool gloss, the green whiting in the back side, the proterties such as leaf color, shape, size, quality have very strong plasticity with impacts such as developmental stage, environment, the large and meat of young leaves, the color pale green, the leaf margin tooth lacks greatly; Little and the keratin of Lao Ye, the leaf margin tooth is little and many.Bloom early spring, brightly yellowish look, and ripening fruits is brown, is commonly called as acorn, for birds and animal provide abundant food source, namely falls after ripe, and seed vitality is lower.The well-drained sandy soil of Virginia oak happiness can salt spray resistance and higher soil salt, and is responsive to soil moisture, can stand moderate arid, and clay also can be grown, and can tolerate the low temperature of minimum-13 ℃.Virginia oak juvenile growth speed, seedling can grow to 4 feet (1.2m) at First Year, and along with growing up of nursery stock, growth rate can reduce.On average can reach 15m the oak that grows up not of hard-core Growth In Space high, the diameter of a cross-section of a tree trunk 1.3 meters above the ground can reach 91-122cm, and more than the tree crown scope can reach 46m, the life-span reached centuries.Virginia oak mainly is distributed in U.S.'s southeastern coast and Gulf of Mexico seashore, namely from Virginia downstate, the Georgia State, Florida State, Louisiana State, until the middle and south, Texas one line; Breathing out the Ma Zhou west and south and Mexico's Northeast Mountain Areas also has fragmentary distribution at the Russia carat, is the important composition seeds in the coastal hard wealthy woods of the U.S. and shrubbery forest land, is widely used as city shade tree and ornamental trees and shrubs in U.S.'s southeastern coast.
The Virginia oak seed that Inst. of Subtropical Forestry, Chinese Academy of Forestry Sciences introduces from Missouri, USA, after seedling, about 5% plant trunk is obvious, and high growth is outstanding, and branch is sparse, and is crown narrow and small; Most nursery stocks do not have obvious trunk, and branches and leaves are intensive, crown the first transaction of a day's business, or be the how dried state of growing thickly.After live oak introduction, all can grow in subtropics, torrid areas such as China Zhejiang, Shanghai, Jiangsu, Fujian, simultaneously because Virginia oak has very strong Salt And Alkali Tolerance ability, well developed root system in addition, germinating property is strong, branch tool toughness, has the ability of resisting hurricane, therefore be widely used in the coast protection forest construction in China's Yangtze River Delta area, having made up the defective that lacks evergreen broad-leaved wind resistance salt tolerant seeds in present China coast protection forest system, is the evergreen tall and big arbor species of unique a kind of salt tolerant in present southeastern coast protection forest system.Simultaneously, acorn has attracted large quantities of birds and animal to collect, and has enriched the bio-diversity of coast protection forest system.Virginia oak also can be used for the public leisure place greening such as garden, park, farm, and its tree crown is wide, and the leaf look vivid, for people good shade, the habitat of Condom and animal.
Every annual meeting produces a large amount of rubbers fruits to Virginia oak in the original producton location, therefore mostly adopts seminal propagation, only has the clone that minority nursery stock company relies on vegetative propagation to obtain various trait to be used for different breeding objectives.The most dependence on import seminal propagation of present domestic Virginia oak nursery stock, but because the Virginia oak seed does not have resting stage, can sprout as long as temperature is suitable, therefore in import kind subprocess, due to reasons such as mechanical damages, make greatly seed can not get sowing in time after sprouting and devitalization causes emergence rate low, seedling cost is higher.Inst. of Subtropical Forestry, Chinese Academy of Forestry Sciences introduces first at home Virginia oak and carries out relevant research, and carried out Virginia oak vegetative propagation technique research, obtained very big breakthrough (ZL200910097684.0) aspect cuttage propagation method of Virginia oak, survival rate can be up to 80-85%.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the invention is to design provides a kind of technical scheme that significantly improves the tissue culturing method for quercus virginiana of its reproduction coefficient, and greatly shortened the Virginia oak growing-seedling period, solve the mode that the dependence on import seed is grown seedlings, saved cost.
