Abstract
The invention relates to a plant seed treatment method and in particular relates to a method for breaking the dormancy of iris barbata hybrid seeds. The method comprises the following steps: peeling off pericarps and naturally drying; soaking the seeds at a room temperature with clean water for 48 hours; soaking the seeds with a 300mmp-1000ppm 6-BA solution for 12-36 hours; and taking out the seeds and sowing. After the seeds treated by the method are sowed, the seeds can germinate after 46-60 days, and the germination rate can reach 75%; the dormancy of the iris barbata hybrid seeds is effectively relieved, and the time that the seeds germinate in March to April in the next year after being sowed in sand under conventional conditions is brought forward to October of the current year and is brought forward for about 6 months; and the germination rate reaches 75%. The breeding progress of iris barbata is accelerated.
Description
Technical field
The present invention relates to a kind of method for treating plant seed, be specially and break the method having whisker Rhizoma Iridis Tectori hybrid seed dormancy.
Background technology
Whisker Rhizoma Iridis Tectori is had to refer to the general designation having beard appurtenance Rhizoma Iridis Tectori on vertical lobe. It is that ornamental flower in modern age is developed the class Rhizoma Iridis Tectori the rapidest, flower change is the most surprising, kind increase is also maximum.
People are by there being the intermolecular hybrid of whisker Rhizoma Iridis Tectori kind to carry out the kind that acquired character is various, but have the seed of whisker Rhizoma Iridis Tectori to there is the characteristic of dormancy. Conventional seed planting emerge late, emergence rate is low, hampers the process of breeding.
Randolph [RandolphLF, CoxLG.FactorsinlfuencingthegerminationofIrisseedAndthere lationofinhibitingsubstancestoembryodormancy [J] .Proc.Amer.Soc.hort.Sci., 1943, 43:284-300.] think, the Germination suppression material in whisker Rhizoma Iridis Tectori seed endosperm is had to hinder the growth of seed germination and seedling, excise endosperm tissue completely or by its inhibiting substances leaching to water, the dormancy of seed is released from [ArdittiJ.andPrayTR.DormancyfactorsinIris (Iridaceae) seeds [J] .AmericanJournalofBotany, 1969, 56 (3): 254-259.]. the special construction of seed coat suppresses the sprouting of seed by the following aspects, and the impermeability of seed coat makes the moisture of q.s can not arrive embryo, the Repiration of seed coat restriction seed, so that seed can not carry out gas exchange with the external world, impacts the breathability of seed, the mechanical inhibition restriction embryo of seed coat breaks through the [Zhou Xia such as seed coat, Zhang Yao. seed dormancy Advance of Physiology summary [J]. Anhui agronomy circular (lower half monthly magazine), 2012,16 (14): 51-53., Fan Lu, Li Shujuan, Zhang Ruilian. illumination and the seed coat impact [J] on there being whisker Rhizoma Iridis Tectori seed germination. Chinese agriculture is circulated a notice of, 2012,26 (12): 200-202.] causing the principal element of iris hybrid seed dormancy is the effect of seed coat and endosperm, and the effect of seed coat and endosperm includes mechanical resistance and containing inhibiting substances.
Hormone is inside plants trace signal molecule, and the whole developmental process of plant is had impact. Plant hormone treatment method is to break one of seed dormant method of Rhizoma Iridis Tectori. Diao Xiaohua have studied gibberellins to the seed dormant impact of Jris Four Plants, find, yellow flag seed germination is had facilitation by gibberellin treatment, and swallow flower, the seed of Radix Iridis ensatae and small stream sweet-smelling grass is insensitive to gibberellins reaction, germination rate do not promote [Diao Xiaohua, Gao Yike. four kinds of iris seed germination and dormancies research [J]. seed, 2006,25 (4): 41-44.].It is blank that the research having whisker Rhizoma Iridis Tectori hybrid seed breaking dormancy aspect is still belonged to.
Summary of the invention
For above-mentioned technical problem, it is an object of the invention to provide a kind of method broken and have whisker Rhizoma Iridis Tectori hybrid seed dormancy so that it is the germinating time of seed in advance, and improves germination percentage. Concrete technical scheme is:
Break the method having whisker Rhizoma Iridis Tectori hybrid seed dormancy, comprise the following steps:
Gather the ripe whisker Rhizoma Iridis Tectori that has and hybridize fruit, peel off peel, choose full seed, through natural drying, be placed in kraft paper bag room temperature storage;
When sowing, the seed of storage is taken out and is placed in room temperature clear water immersion 48h;
Soaked for clear water seed is taken out, is placed in 300ppm-1000ppm6-BA solution soaking 12h-36h, take out sowing.
6-BA is 6-benzyl aminoadenine.
Provided by the invention breaking the method having whisker Rhizoma Iridis Tectori hybrid seed dormancy, about 46-60d after the planting seed processed, germination percentage is up to 75%; Efficient solution is except there being whisker Rhizoma Iridis Tectori hybrid seed dormancy, and being hidden by sand under normal condition after planting germinates in next year 3-4 month advances to October then, and about about 6 months in advance, germination percentage reached 75%. Accelerate Rhizoma Iridis Tectori breeding process.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described, embodiment scheme described here, it is not intended to the present invention, those skilled in the art is according to the spirit of the present invention, can make improvements and change, described these improve and change is regarded as in the scope of the invention, and the requirement of all having the right of the scope of the present invention and essence limits.
