Description
Technical field
The present invention relates in plant sexual reproduction process, particularly manually help a kind of pollen isolating device used in sexual reproduction process.
Background technology
Hybridization refers to the mating between the parent that two genetic constitution is different, and the offspring produced is called hybrid.For forest species, hybridization typically refers to the mating of different tree species or same seeds different cultivars or dissimilar.Trees hybridization is a kind of method effectively integrating excellent genes, is cultivate the important of new varieties in traditional breeding method and means fast.Hybridization produce hybrid may have the distinctive good characteristic of parents, may be stronger than parent in growth potential, productivity or resistance, this just made breeding research personnel have select space, the cultivation for new varieties provides basic seed selection material.
On tree, crossover process comprises: 1) hybrid strain is selected; 2) the blooming of trees, pollinate and Fruiting Characters investigation; 3) pollen collection; 4) pollen transport and storage; 5) Pollen Activity qualification; 6) emasculation; 7) bagging; 8) pollinate; 9) bag is removed.Wherein bagging is an important step in trees crossover process.Bagging is the pollution in order to prevent non-object pollen, before stamen loose powder and after artificial pollination, gynoecium is played to the effect of insulation blocking.For unisexual seeds, before stamen loose powder, or get final product bagging when female flower breaks through perula; For androgyny seeds, before stamen loose powder artificial removal's stamen or use some chemical reagent to kill stamen, then bagging.Wait for that gynoecium is to awarding the phase, can pollinate during secretion stigma mucus.Entomophilous flower can extract bagging between pollination period, puts after having pollinated again; Anemophilous flower will accomplish pollination in bag as far as possible.Will wait until that amphigamy completes after pollination terminates, column cap just can remove bag after having crossed and can having awarded the phase.So protect gynoecium activity during bagging, can keep good Pistil recipient phase, after pollination, can pollen be sprouted and can pollen tube arrive ovule smoothly to complete amphigamy most important smoothly.
In crop hybrid process becomes, researcher possesses some special knowledge to the material of institute's bagging and shape.In conventional hybridization process, the making material of bagging is generally based on template or ox (sheep) mulberry paper, entomophilous flower can make sack with crocus cloth or fly net, shape is envelope shape, both ends open or minor face opening, the downward convolution in top during use, pin with paper clip, lower port lining, with cotton, is strapped on old branch with line.People is had now to make the corresponding changes on its basis, the such as patent No. is the utility model patent " a kind of wheat hybridizing bag " of CN201422309Y, this patent comprises a sheet bag, long 15 ~ 20cm, wide 12 ~ 15cm, two-sided tape is stained with in an edge of sheet bag, tear adhesive tape during use, the wheat head is wrapped in the inside and sticks into bag, compared with traditional ox (sheep) mulberry paper bag, change 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 isolating locust tree inflorescence, because locust tree inflorescence is large, bag wall can form extruding to locust tree little Hua, makes Pagoda Flower can not normal growth.Bag wall because with undue contact of the little Hua on locust tree inflorescence and produce friction, easily cause the damage of stylet head, affect Pollination Effect, and then reduction ripening rate.And for example the patent No. is the utility model patent " pollination isolating hood " of 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: inserted the support bar lower end of cage in soil, up build from ground one higher than 100 centimetres, be wider than 70 centimetres, length is the cage of 120 centimetres, the material not only needed is many, nearly 10 kilograms of weight, and not easily move, be difficult to recycle, the cost of each cage is in 60-70 unit, service life only has 2-3, and 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 No. is the patent of invention " pollen isolating device of cross pollinated plant " of CN1709039A, this patent is made up of cuboid framework and outer cover, cuboid framework comprises two long bend pipes of N-shaped and two short bend pipes of N-shaped, is connected between long bend pipe with short bend pipe by sleeve pipe.Being covered with a side adopts plastic foil to make, and its lap is made up of dense cloth, but this invention is also the spacer assembly built on the ground, can only carry out whole strain isolation, be not suitable for the isolation to pollen on tall and big trees equally for short crop to it.The first, it is large that trees itself are compared to object height, and carrying out overall isolation to it wastes time and energy, and improves cost; Second, the colored property of trees, pollination pattern are different with mating pattern, what have is dioecism, what have is the different flower of monoecism, have be monoecism color, have for insect pollination have be wind pollination, some Self-Incompatibility, some self-compatible, so also will see concrete condition when carrying out overall isolation to trees.Locust tree is monoecism color, self-compatible seeds, first emasculation is wanted when it is hybridized, and every flower growth and development set is inconsistent, flower amount is large, emasculation can not be carried out to all Huadus on whole strain tree, if all emasculation is not only large to isolating tree injury, and time-consuming, operation also inconvenience; Even if only selection portion divides spray to carry out the process of emasculation bagging, be also enough to meet its crossbreeding work, therefore, there is no need to isolate whole tree.In view of this above-mentioned patent is not suitable for for the isolation of trees, is necessary to develop the device for the isolation pollen of forest tree species own characteristic.
The research of trees crossbreeding is later than crop hybrid breeding, and the use of hybridization bag has followed the hybridization bag principle in traditional crop crossover process, namely uses the envelope shape sack that template, ox (sheep) mulberry paper, crocus cloth, fly net are made.But relative to crop hybrid, it is large that trees have tree height, florescence is long, with the feature that the florescence of one tree diverse location is inconsistent, and taking net to whole tree or several trees isolates unrealistic, 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 just occurred above the hybridization bag mentioned to the influential problem of gynoecium vigor.
Locust tree is Papilionaceae, raceme, androgyny, close colored loose powder, part selfing, so stamen will be removed before loose powder, during emasculation, need the keel destroying flower---the petal of parcel gynoecium originally, thus 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 directly can contact with gynoecium, and during bagging, bag body can wave with the wind, bag wall and gynoecium especially phase mutual friction between column cap, very easily damage column cap, make column cap lose Enumerable infinite set, thus cause hybridizing unsuccessfully; Secondly, locust tree inflorescence is large and be distributed on sprig, and form T font between spray, hybridization bag is not easy to be fixed on sprig, be easy to slide downward again when being fixed on raceme end, under wind action, little Hua falls from strip rhachis the most at last, causes extreme loss to crossing work, increase the machine error of data statistics, affect final experimental result; Again, bagging time isolation period is long, at least takes 7 days, rainproofly can not to solve with ventilatory problem simultaneously, airtightly can affect colored normal development, the not rainproof pollen envelop be 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.
