Description

Quick and high-efficiency cephalotaxus hainanensis seed seedling breeding method
Technical field
The present invention relates to the seed seedling quick efficient breeding method of a plant species, particularly quick and high-efficiency cephalotaxus hainanensis seed seedling breeding method.
Background technology
Cephalotaxus mannii (Cephalotaxus hainanensis Li) is the Cephalotaxaceae plant, and another name cephalotaxus hainanensis, slender lobule bamboo comb China fir are perennial tall and big aiphyllium.Be the distinctive rare tree species of China, its distribution is very narrow, is detected in some areas such as Hainan and Guangdong, Yunnan.Studies show that the not only effective alkaloid of Cephalotaxus mannii is the highest in the Cephalotaxaceae, and curative effect is the most remarkable, is one of best anticancer seeds of generally acknowledging at present.These seeds are cut down repeatly because of material is good in addition, and population quantity is few in addition, are one of most important rare or endangered species of China.But this seeds natural resources is very limited, is difficult to satisfy growing demand.Because that these seeds are dioecism, seed production and germination rate is very low (the only tens of grain of annual every female plant, seed germination rate open-air about 10% (is that Hainan is difficult to satisfy because the Cephalotaxus mannii seed germination needs the low temperature breaking dormancy on the one hand; On the other hand the Cephalotaxus mannii seed very easy in the open air by animal gnaw, tradition is artificial sprouts about 20%); and the open-air and traditional germination method needs of Cephalotaxus mannii seed are about, and the time could Cheng Miao more than 1 year; be subjected to factor such as its ecological and artificial destruction in addition and cause the endangered (Wang Xianpu of Cephalotaxus mannii; Wang Yousheng. reason that Cephalotaxus mannii is in imminent danger and safeguard measure. GUIHAIA; 1994,14 (4): 369-372).Though also the someone studies the employing cottage propagation, but under the endangered situation of germ plasm resource, provide the difficulty of a large amount of nursery stocks very big by cuttage, do not satisfy the demand of pharmaceutical industry far away, and can cause bigger destruction the limited resources of Cephalotaxus mannii to Cephalotaxus mannii; And data shows that cuttage tender stem segments source directly has influence on cuttage growth of seedlings situation, and only deriving from the seedling that the young shoot cuttage on stem top produces can normal upright well grow; And stem top tender stem segments is drawn materials and can directly be destroyed the normal growth of this strain plant.So, cottage propagation can not promote substantially (Fu Wenying, Pan Xuefeng, Chen Xiuhui, Liu its people, Li Renzhu. the Cephalotaxus mannii cuttage and the experimental study of taking root. University Of Hainan's journal (natural science edition), 1997,15 (3): 239-244; Pan Xuefeng, Fu Wenying, Chen Xiuhui, Liu its people, Li Renzhu. the research of Cephalotaxus mannii cottage propagation. tropical agriculture science, 1996, (3): 25-30; Du Daolin, Fu Wenying. rare or endangered species Cephalotaxus mannii population protection bioecology. Hunan science and technology publishing house, 2003.11).Also the someone studies and adopts traditional method for tissue culture that Cephalotaxus mannii is carried out the seedling breeding in addition, but can not emerge substantially, perhaps emergence rate is very low, can not carry out application (Fu Wenying, Du Daolin, tally is equal. the inducing and cultivating of Cephalotaxus mannii callus. and Plant Physiology Communications, 2004,40 (1): 34-36; Li Zhiying, Wang Zhunian, Xu Li. the breeding fast of exsomatizing of Cephalotaxus mannii. Plant Physiology Communications, 2005,41 (5): 786).
Given this, the species conservation of Cephalotaxus mannii causes the great attention of botany research institution.So; the invention provides a kind of systems approach of directly rapidly and efficiently growing seedlings with the Cephalotaxus mannii seed; can realize improving seed germination bud ratio to 90% above (having improved about 70%); seedling survives and surpasses 90% (having improved about 60%); become seedling time ratio conventional method to shorten more than 2/3; and the high-quality Cephalotaxus mannii seedling of production neat and consistent; also utilized extremely limited Cephalotaxus mannii seed resource to greatest extent; the rare or endangered species Cephalotaxus mannii is fast numerous to provide technical guarantee with recovery and protection and resources development and utilization in order to solve, to satisfy this rare or endangered species seedling active demand of Cephalotaxus mannii.
Summary of the invention
The key technical problem that the present invention solves is directly rapidly and efficiently to grow seedlings with the Cephalotaxus mannii seed; improve more than the seed germination bud ratio to 90%; seedling survives and surpasses 90%; become seedling time ratio conventional method to shorten more than 2/3; and the high-quality Cephalotaxus mannii seedling of production neat and consistent, the rare or endangered species Cephalotaxus mannii is fast numerous to provide technical guarantee with recovery and protection and resources development and utilization in order to solve.
The technical problem to be solved in the present invention is to be brood body with the Cephalotaxus mannii seed, and a whole set of Cephalotaxus mannii seedling method for quickly breeding is provided.The technical scheme that addresses the above problem comprises the steps:
(1) seed collection: collect and grow near ripe or ripe Cephalotaxus mannii seed;
(2) cleaning and sterilization of seed: with Cephalotaxus mannii seed bath 1-3h., and clean up with distilled water, put into about 0.5-2.0% liquor natrii hypochloritis vacuum filtration about 3-8min that sterilizes after filter paper blots, sterile water washes 3-6 time repeatedly then;
(3) seed low temperature breaking dormancy: the good Cephalotaxus mannii seed of will sterilizing places 1-6 ℃ low-temperature preservation 1-3 week, removes Seed Dormancy;
(4) seed asepsis sprouting: the seed of breaking dormancy is put into the about 3-8min of about 0.5-2.0% liquor natrii hypochloritis vacuum filtration sterilization again, and sterile water washes 2-5 time repeatedly then; Then seed is inoculated on the following medium and cultivates: 0.5-1MS (Murashige and Skoog Stock medium)+0.01-0.1mgL -16-BA (6-benzyl purine)+0-100mgL -1Inositol+0.2-0.6% agar+1-5% sucrose+1-5% coconut milk, pH value 5.0-6.0; Place periodicity of illumination 16hd again behind the dark cultivation 2d -1, intensity of illumination 2000-3000Lux cold light lamp under, continue in 25 ± 2 ℃ of the environmental temperatures to cultivate 15-25d, just obtain the seedling that root is arranged of new green, emergence rate surpasses 90%;
(5) domestication is transplanted: the good seedling that will take root moves to domestication chamber, intensity of illumination 10000-30000Lux, domestication 1-2 week, seedling is taken out from test tube, with warm water washing shoot root portion medium, use cold water flush again, transplant to volume ratio be coconut palm chaff: river sand=1-3: in 1 or vermiculite: perlite: peat=1-3: 1-3: the 1 basin dress artificial substratum that mixes, every basin seedling puts transparent plastic bag, every 3 days sack is cut an osculum, and 9-12d goes basin seedling transparent plastic bag to move to hot-house culture; 1-2 moves into flowerpot respectively after week or a bag seedling is made in pack, and the matrix main component is cultivated 1-2 week again by fetched earth from open-air Cephalotaxus mannii group earth and humus, can change outdoor booth incubation growth over to; Seedling percent reaches more than 90%.
The invention has the beneficial effects as follows: directly rapidly and efficiently grow seedlings with the Cephalotaxus mannii seed; improve seed germination bud ratio to 90% above (having improved about 70%); seedling survives and surpasses 90% (having improved about 60%); become seedling time ratio conventional method to shorten more than 2/3; and the high-quality Cephalotaxus mannii seedling of production neat and consistent, the rare or endangered species Cephalotaxus mannii is fast numerous to provide technical guarantee with recovery and protection and resources development and utilization in order to solve.
