Abstract
The method for rapid propagation of potamogeton crispus seedlings includes the following steps: firstly, collecting potamogeton crispus plant from natural water body or greenhouse, making pretreatment and cleaning its surface, removing plant leaf and root, using the stem portion closed to top, sterilizing completely, cutting stem segment, placing the stem segment on the solid culure medium containing hormone to induce budding, transferring the bud with a certain length to propagation culture medium to make amplification culture, then making rooting culture and seedling naturalization, then planting the seedling in natural water body.
Description
Technical field
The present invention relates to the quick propagating technology of water caltrop seed and seedling, also relate to the method for water caltrop stipes tissue culture.Be applicable to that aquatic vegetation recovers a large amount of seedling demands of engineering, also can be aquatic garden landscape, ornamental waterweed is cultivated that seedling is provided, and provide aseptic seedling for water caltrop research.
Background technology
In recent years, along with the implementation of national sustainable development strategy, and the raising of social development level and people's quality of life, the improvement of water pollution control and quality of water environment has caused the strong interest of the whole society.Country has all worked out relevant plan with local, or has carried out relevant scientific research and engineering project.As Tenth Five-Year Plan Period, the Ministry of Science and Technology as one of 12 major scientific and technological projects of country, has carried out Water Ecological Recovery engineering on Taihu Lake, Wuxi, Kunming Dianchi lake, Shenzhen, Shanghai, Zhenjiang and other places with " water pollution control technology and improvement engineering "; State Environmental Protection Administration has worked out " three rivers " " three lakes " water prevention and cure of pollution the Tenth Five-Year Plan (2001-2005) together with department such as national development and the reform committee and government of relevant provinces, autonomous regions and municipalities, and State Council's reply is implemented." plan " determined 1590 projects altogether, 1,234 hundred million yuan of gross investments.
Water pollute and the measure of the improvement of quality of water environment in, cutting under the dirty prerequisite, rebuild water ecosystem, the self-purification capacity of the aquatic ecosystem of getting well is considered to solve steadily in the long term the essential measure of water pollution.As the key members of aquatic ecosystem, submerged plant not only plays an important role aspect perching water body food web, the supply of water body dissolved oxygen, nutrition circulation, aquatic animal, and has proved that submerged vegetation is a key factor of keeping the clean waters state.Yet the eutrophication of water body and the excessive herbivorous fishes of culturing have caused the extensive degeneration of submerged vegetation, so the recovery of submerged vegetation is the committed step during water pollution is administered.At Dian Chi water pollution control environment-friendly engineering, in the engineering projects such as country's major scientific and technological project " area, Hanyang, Wuhan City quality of water environment improves technology and comprehensive demonstration ", " Taihu Lake water pollution control and water body recovery technique and engineering demonstration ", the recovery of submerged vegetation all is a key content wherein.
The recovery engineering of aquatic vegetation must be brought the wilderness demand to the water plants seedling.Usually every square metre of water surface needs 5-10 strain (root and stem of certain plants) water plants seedling, and every square kilometre of water surface then needs the up to ten million strains of seedling (root and stem of certain plants), even every strain seedling is pressed 0.2 yuan of calculating, the expense of every square kilometre of required seedling of the water surface also reaches 2,000,000 yuan.The seedling that uses in the recovery engineering of aquatic vegetation at present is to fish for from natural water fully, the way that this method comes down to rob Peter to pay Paul, not only the water plants resource to source of seedling ground damages, in fact also often run into the shortage of seedling resource, promptly can't obtain enough seedling amounts of certain plants.In addition, the acquisition of water plants seedling also usually is subjected to the influence in season.Therefore, in order to satisfy the active demand of water plants seedling, be badly in need of the new source mode of the aquatic plant seedling of development.The approach of breeding water plants fast by the mode of Plant Tissue Breeding is a kind of production method of feasible fully water plants seedling.Plant Tissue Breeding is by the part of sterile working separating plant body, is inoculated into medium, develops into the process of whole plant under the manual control condition.This class mode has been widely used in the fast seedling growing of crop, medicinal plant, economy forest and famous-brand and high-quality flowers.This method can go out a large amount of seedlings from number strain plant production at short notice, and not only floor space is little, and is not subjected to seasonal effect, and the seedling of producing has been removed plant virus, and proterties is more good.Aspect the seedling of economy plant, the home and abroad all has a large amount of companies to be engaged in commercial production, and it is numerous soon to carry out orchid as the many areas in the U.S., Europe and Southeast Asia with tissue culture method, has become famous " orchid industry ".Aspect ecological recovery, existing three the commercial laboratories of the U.S. utilize this mode to produce the recovery engineering that hygrophyte is used for wetlands ecosystems.
Water caltrop is the common submerged plant of China's shallow lake, and durability against pollution is preferably arranged, the pionner of Chang Zuowei aquatic vegetation reconstruction engineering first-selection.Because the epidermis of submerged plant is strong to the permeability of bactericide, be that the tissue culture of explant is more more difficult than terrestrial plant therefore with root, stem, leaf.External at present report submerged plant watermifoil and the training of Potamogeton pectinatus L group are set up.Yet there are no report with the water caltrop stem as the tissue-culturing rapid propagation of explant.
Summary of the invention
The object of the present invention is to provide a kind of method of fast breeding water caltrop seed and seedling, effectively solve a large amount of supply and demand problems of water caltrop seed and seedling, material is easy to obtain, process fast, is not subjected to seasonal effect, with low cost.
In order to achieve the above object, the present invention has adopted following technical scheme:
1, gather in the natural water or the water caltrop seedling of the robust growth of cultivating in the greenhouse;
2, with running water flushing 1-2 hour, defoliation and root were got the sturdy stem on top, use distilled water flushing 2-3 time, clean the water caltrop stem;
3, inducing of sterilization and bud: adopt bactericidal agent PPM (Plant preserve Mixture), ethanol, clorox and hydrogen peroxide etc. to the degerming of stem explant.Its degerming mode is for 50% ethanol sterilization 1 minute, then with sterile distilled water flushing three times, again with 1/100 milliliters sterilizations of 1.05%NaClO+ Tween-20 10-20 minute, at last with sterile distilled water flushing three times; Or 5%H
