Description
Technical field
The present invention relates in plant sexual reproduction process, particularly manually help a kind of pollen isolating device using in sexual reproduction process.
Background technology
Hybridization refers to the mating between the different parent of two genetic constitution, and the offspring who produces is called hybrid.For forest species, hybridization typically refers to different tree species or same seeds different cultivars or dissimilar 's mating.Trees hybridization is a kind of method that effectively integrates excellent genes, is in traditional breeding method, to cultivate the important of new varieties and means fast.The hybrid that hybridization produces may have the distinctive good characteristic of parents, may be stronger than parent aspect growth potential, productivity or resistance, and this just makes breeding research personnel have the space of selecting, for the cultivation of new varieties provides basic seed selection material.
On tree, crossover process comprises: 1) hybrid strain is selected; 2) the blooming of trees, pollination and Fruiting Characters investigation; 3) pollen collection; 4) pollen transportation and storage; 5) Pollen Activity is identified; 6) emasculation; 7) bagging; 8) pollination; 9) remove bag.Wherein bagging is an important step in trees crossover process.Bagging is in order to prevent the pollution of non-object pollen, before stamen loose powder and after artificial pollination, gynoecium is played the effect of insulation blocking.For unisexual seeds, before stamen loose powder, or female flower gets final product bagging while breaking through perula; For androgyny seeds, be before stamen loose powder artificial removal's stamen or use some chemical reagent to kill stamen, then bagging.Wait gynoecium, to awarding the phase, can be pollinated during secretion stigma mucus.Entomophilous flower can be extractd bagging between pollination period, after having pollinated, puts again; Anemophilous flower will be accomplished pollination in bag as far as possible.After pollination finishes, will wait until that amphigamy completes, column cap just can remove bag after having crossed and can having awarded the phase.So can protect gynoecium activity during bagging, keep good awarding property of column cap, after pollination, can pollen be sprouted and can pollen tube arrive smoothly ovule to complete amphigamy most important smoothly.
In crop hybrid process becomes, researcher possesses some special knowledge to material and the shape of institute's bagging.In conventional hybridization process, the making material of bagging generally be take template or ox (sheep) mulberry paper as main, entomophilous flower can be made sack with crocus cloth or fly net, be shaped as envelope shape, both ends open or minor face opening, the downward convolution in top during use, with paper clip, pin, lower port serves as a contrast with cotton, with line, is strapped on old branch.There is now people to make the corresponding changes on its basis, the utility model patent that for example patent No. is CN201422309Y " a kind of wheat hybridizing bag ", this patent comprises a sheet bag, long 15～20cm, wide 12～15cm, in the Yi Tiao of sheet bag edge, be stained with two-sided tape, during use, tear adhesive tape, the wheat head is wrapped in to the inside and sticks into bag, compare with traditional ox (sheep) mulberry paper bag, changed assembling mode, more convenient than ox (sheep) sack made by leather in use.This kind of bag shape flat, is applicable to wheat and uses, and when locust tree inflorescence is isolated, because locust tree inflorescence is large, bag wall can form extruding to locust tree little Hua, makes the Pagoda Flower can not normal growth.Bag wall produces friction because of undue contact of the little Hua with on locust tree inflorescence, easily causes the damage of stylet head, affects Pollination Effect, and then reduces ripening rate.The utility model patent " pollination isolating hood " that and for example patent No. is CN201839678U, this patent comprises a quadra, framework upper end is provided with screen cloth, all gussets are provided with plastic film, concrete using method is: the support bar lower end of cage is inserted in soil, from ground, up build one higher than 100 centimetres, be wider than 70 centimetres, length is the cage of 120 centimetres, the material that not only needs is many, nearly 10 kilograms of weight, and be difficult for moving, being difficult to recycle, the cost of each cage is in 60-70 unit, only have 2-3 service life, cost is higher.This patent is only applicable to isolate whole strain or the short crop plants of a few strain, is unsuitable for tall and big trees.For another example the patent of invention that the patent No. is CN1709039A " pollen isolating device of cross pollinated plant ", this patent is comprised of cuboid framework and outer cover, cuboid framework comprises two long bend pipes of N-shaped and two short bend pipes of N-shaped, between long bend pipe and short bend pipe, by sleeve pipe, is connected.Be covered with a side and adopt plastic foil to make, its lap is made by dense cloth, but this invention is also a spacer assembly of building on the ground, can only to it, carry out whole strain isolation for short crop, is not suitable for equally the isolation to pollen on tall and big trees.The first, it is large that trees itself liken object height to, and it is carried out to overall isolation wastes time and energy, and has improved cost; Second, the colored property of trees, pollination mode are different with mating pattern, what have is dioecism, what have is the different flower of monoecism, what have is monoecism color, have what have for insect pollination is wind pollination, some selfings are not affine, some self-compatible, so also will see concrete condition when trees are carried out to overall isolation.Locust tree is monoecism color, self-compatible seeds, when being hybridized, it wants first emasculation, and flower growth and development on every tree is inconsistent, flower amount is large, can not carry out emasculation to all Huadus on whole strain tree, if all emasculation is not only large to isolation tree injury, and time-consuming, operation is also inconvenient; Even if only selection portion divides spray to carry out the processing of emasculation bagging, be also enough to meet its crossbreeding work, therefore, there is no need whole tree to isolate.In view of this above-mentioned patent is not suitable for for the isolation of trees, is necessary that exploitation is for the device of the isolation pollen of forest tree species own characteristic.
The research of trees crossbreeding is later than crop hybrid breeding, has followed the hybridization bag principle in traditional crop hybrid process in the use of hybridization bag, the envelope shape sack that uses template, ox (sheep) mulberry paper, crocus cloth, fly net to make.Yet with respect to crop hybrid, it is large that trees have tree height, florescence is long, inconsistent feature of florescence with one tree diverse location, and it is unrealistic that whole tree or several trees are taken to net isolation, especially androgyny self-compatible seeds again, also have the problem of an emasculation, so can only carry out bagging isolation to local (training, inflorescence) in trees crossover process.It should be noted that this has just occurred that the hybridization bag of mentioning is to the influential problem of gynoecium vigor above.
Locust tree is Papilionaceae, raceme, androgyny, close colored loose powder, part selfing, so stamen will be removed before loose powder, need to destroy colored keel during emasculation---originally wrap up the petal of gynoecium, thereby there will be following problem: first, after emasculation, the column cap of gynoecium is easy to be exposed to outside, during bagging, bag self does not have supporting role, and bag wall can directly contact with gynoecium, and during bagging, bag body can wave with the wind, bag wall and especially phase mutual friction between column cap of gynoecium, very easily damage column cap, make column cap lose awarding property, thereby cause hybridizing unsuccessfully; Secondly, locust tree inflorescence is large and be distributed on sprig, and between spray, form T font, hybridization bag is not easy to be fixed on sprig, when being fixed on raceme end, be easy to again down sliding, under wind action, little Hua strip from rhachis falls the most at last, and crossing work is caused to very big loss, strengthen the machine error of data statistics, affected final experimental result; Again, bagging time isolation period is long, at least takes 7 days, rainproof and ventilative problem can not solve simultaneously, the airtight normal development that can affect flower, the not rainproof pollen envelop being exposed on outer column cap that can make again washes out, and existing hybridization bag can not be applicable to the crossbreeding of locust tree.
